Modbus%2C Despatch oven and Protocol 3

I have a Despatch oven that is using Protocol 3 which communicates using Modbus over RS485. I am using the Modbus library that I found though the forum and am still having troubles communicating with the controller. I am using a USB RS485 converter and my converter is set to half duplex 2 wire without echo. I am able to transmit but not receive a message back from the oven. Does anyone have any experience or any insight on how to work LabVIEW with this equipment?

Hi ncm,
NI officially supports the modbus libraries that ship with both the DSC Module and the Real-Time Module. The free download is unsupported, but there is a forum that might assist you. Please post your question to the Industrial Communications forum page.
Thanks!

Hi ncm
Could you please share a diagram of the wiring that you used for the half duplex connection?
Do you have further information about the oven (a manual for example? If you could post screenshots of the code that you use would be useful as well. I wonder if there is any configuration that needs to be done to allow reading values from the oven.

Sending email to 10,000 addresses without knowing Host and Protocols!!

Context:
I am building an "eMail Marketing Campaign" application which takes a list of email addresses (unlimited) and sends an eMail to all of them.
My servlet creates an instance of "MyMailHandler.java/class" and passes a list of addresses.
Problem:
If I want to send email to different user, do I need to know about everyOne's HOST and PROTOCOL. My application recieves list of addresses from a remote server of a data-selling-company so they don't have that info.
Following is the code (hardCode!) of MyMailHandler.
properties.put("mail.smtp.host", "MAIL.DMCDATABASE.COM");
properties.put("mail.transport.protocol", "IMAP");
Question:
How do I send emails to receivers without knowing everyOne's host and Protocol?????? (new to JavaMail)

No, you only need to know the name of your own mail host. It will send the e-mails to those 10,000 addresses for you. And the protocol for sending mail is SMTP, that's all you need to know to send mail. IMAP and POP are protocols for storing received mail messages and so are not relevant to your task.

Exchange 2010 Required Communication (Firewall Ports and Protocols)

Forgive me if this question has been asked before, but a search did not give me much on my scenario.
We currently have one Forest with multiple Domains and Child Domains. We have two departments that have Exchange 2010 running and control their own individual users and mailboxes inside their Domains. These two Exchange servers communicate with each other
just fine.
We now have a department (another domain) that needs control of their own Exchange 2010 server, but here is the catch. They are behind a Firewall. My question is, what Ports and Protocols do I need opened for the Exchange server behind the Firewall to properly
communicate to the two other Exchange servers knowing that the Exchange Environment is a Forest wide activity.
At this point in time, we cannot get Exchange installed as the prereq check fails with an error that we need to prep the AD schema for Exchange, but we know this has been done since we have to other servers in the Forest.
Perhaps we need ports not only opened to the two other exchange servers, but also the Forest Root controller?
Any help is appreciated.

Exchange needs to be able to fully access all other Exchange servers, Active Directory Domain Controllers, and Active Directory Global Catalogs. Additionally, if I remember correctly, there was a blog from the Exchange team a couple of years ago that said
Exchange wasn't supported with firewalls between the various Exchange servers in the environment.
I will ask one question - why aren't you centralizing your Exchange management and servers, and granting rights to these groups for their mailbox management (based on an Organizational Unit that their accounts are in, and granted at the Active Directory
level)? You would no longer have this issue each time another group decides they want to host their own Exchange system.

P2P chat client and protocol

Hi everybody, I am a newbie with P2P, so bear with me if I ask dumb. I have been doing some research but P2P part is still not clear to me. I want to implement a chat client that works as P2P (text chat) in Java and my own protocol. As I understand Jxta defines a set of protocols that developers can use to build p2p application , but I have to create and use my own protocol for exchanging chat messages. Am I required to implement all six of Jxta protocols? Is there any open source P2P chat client and protocol? Any pointers on how to do this would be very helpful.

JXTA is mainly for discovery and session setup as well as mapping.
As you want to create your own communications protocol, it would b best for you to start from scratch, and not use another API.
You can create a client application that contains a server and a socket.
The socket allows you to connect to the remote user, while the server allows you to accept connections from other users. Anytime the two clients are running and attempt to connect to either one, they can setup a session.
How your client will send/receieve messages is up to you - that would be your protocol.

B-channel oos and protocol error 510

Dear all,
I have some some issue couple of days ago. The telephony system of my client worked well and suddenly the cannot make external calls via E1. I checked the config and for me it seems to be ok. When I checked the SDL file, I can see the B channel out of service error message following by the
"MGCP PROTOCOL ERROR: <S1/SU1/DS1-0/[email protected]> CRCX error code: 510". They have A CUCM 6.0 and Cisco 2821 as gateway with 12.4 (25f) advance IP service IOS.
I perform the following actions without success:
-From the CUCM in the advance service I forced the Bchannel to bring it in service,
- no mgcp/mgcp, -reboot the CUCM and the Gateway,
-reset the controller throug CUCM,... in vain.
They contacted telco and has confirm that everything seems to be ok. Find below the information that can help you to undestand better

Thanks for your help

The explanation for your syslog message is " The B-channel indicated by this alarm has gone out of service. Some of the more common reasons for a B-channel to go out of service include: Taking the channel out of service intentionally to perform maintenance on either the near- or far-end; MGCP gateway returns an error code 501 or 510 for a MGCP command sent from Cisco Unified Communications Manager (Unified CM); MGCP gateway doesn't respond to an MGCP command sent by Unified CM three times; a speed and duplex mismatch exists on the Ethernet port between Unified CM and the MGCP gateway"
Recommended action:
Check the Unified CM advanced service parameter, Change B-channel Maintenance Status to determine if the B-channel has been taken out of service intentionally; Check the Q.931 trace for PRI SERVICE message to determine whether a PSTN provider has taken the B-channel out of service; Reset the MGCP gateway; Check the speed and duplex settings on the Ethernet port.

Process Failure when communicating over MODBUS using LabVIEW 2011 and DSC

I'm currently trying to read from a PLC's holding registers using MODBUS/TCP. I've confirmed that the PLC is updating the values and responding to MODBUS communication correctly using a third party program called Modbus Poll. However, when I try to poll the PLC using LabVIEW's shared variable engine, I am unable to read any values from the same addresses that I'm viewing with Modbus Poll.
My setup simply consists of a PC connected directly to the PLC over Ethernet, with no router in between. I am using LabVIEW 2011 SP1 with the DSC module.
I opened the NI Distributed Systems Manager to view the status of all shared variables in the Modbus library that I created and I've noticed that the CommFail bit is permanently set to "true". All other variables with a "read" access mode report "Process Failure". I've tried restarting the process as well as stopping and starting the local variable engine with no success. I've also restarted my computer several times to see if any services were failing, but this does not seem to have fixed the problem.
I finally resorted to monitoring communications over the network card that I have the PLC plugged into via Ethernet using Wireshark and I've found that while Modbus Poll is communicating with the PLC, many MODBUS and TCP packets are sent and received. However, when solely using LabVIEW or the NI DSM to communicate with the PLC, there does not appear to be any communication over the network card.
Something that may be worth noting is that I was able to communicate with the PLC and read values from it with the DSM on just one occasion, when I first figured out which addresses I should be reading from. It all stopped working shortly thereafter. Prior to this, "CommFail" was not usually set to "true" with my current configuration. Thinking that it was my firewall, I have since turned my firewall off, but this seems to have had no effect on the problem either.
Any help on this matter would be appreciated.
Solved!

Just a thought but I think the register addresses used by LabVIEW are one off of the actual register #. I was using a CRIO as a modbus IO Server and had to shift the register addresses by 1 to get things to work correctly (can;t recall if it was +1 or -1). This is documented somewhere on ni.com but can;t seem to find it now. But here is another link that may help:

Advantages and protocol on listing a page of links to other sites

Hi, Once again, I have questions about my site www.freemodelguild.com. the question is more a general question for experienced web designers not about Muse specifically.
Most of the art groups in our area have a page that lists all the other art groups in the area, and so this organization is suggesting we do the same thing. I know having other links on a site can help with our search engine optimization, and we are trying to drive traffic to our site, so I think it's a good idea. However, should I just copy a list of all the other arts organizations? Should I write to their webmasters and ask them to link to us? Should I write and ask for permission to link to them? I just don't know what the protocol is.
Again this is such a non-web savvy group, they know they want a website, but have no idea what should and could be done so I've had wing this thing. I'm a print designer and, of course, things are done a little differently with print.
I appreciate all the feedback I get from this forum.

Generally you would have no problem adding links to other sites without asking. No website owner will tell you you can't as the more links they have coming to their site the better. I have always had mixed feelings on that type of thing. One thing to remember is the more external links you have the more work it is to make sure they all work. Dead links make your site look bad as well as bad for search engines so you would have to constantly be checking that the sites are still operational or the link hasn't changed.
So over the years I personally have found it better to just supply a small handful of links (maybe no more than 5) that I think will benifit my site visitors directly. Almost always it is a very well established long standing site so I know it is worthwhile/relevant and most likely not to dissapear.
Remember that when you do link to an external site to set the target to open in a new browser window. Also keep in mind that the more external links you have the more you are pushing your visitor to somewhere else.

SOAP Adapter And Protocol issue

Why and when we use SOAP adapter ? Does Xi uses processed XML messages using SOAP protocol ? I am new to Xi and confused over the issue. Can anyone please explain this to me. Thanks for your time.

HI KM
When you want to Send Data to XI from a Webservice and vice versa, your SOAP adapter is used.
Check these links for reference...

A SOAP adapter is used in order to post messages to a webservice or provide a web service for receiving messages.

SOAP adapters are used for communicating with the WEB SERVICE. Web service is a software system designed to support interoperable Machine-to-Machine interaction over a network. Web services are frequently just Web APIs that can be accessed over a network, such as the Internet, and executed on a remote system hosting the requested services. In common usage Web Service refers to clients and servers that communicate using XML messages that follow the SOAP standard. So we communicate the WEB SERVICE using the SOAP adapters.
This is an example WEB SERVICE which follows the SOAP standards

Messages,commands and protocols

I need to make the attached protocol ... The idea is that this is considered as a conversation between the interrogator and the tag and I've already made the commands "select / Query / Ack / QueryRep" with boolean array output ...The problem is that I need something in Labview like msg and In case of getting a response action I will take a specific action BUT after waiting sometime "T4 / T1 /T2 " as timeout I need to take another action ..... what blocks I must use "putting in consediration that I have the commands (select / Query / Ack / QueryRep) with boolean array output" .... thanks In advance

OK, what have you tried? This is a great homework problem that you can use to develop some good LabVIEW skills (so we shouldn't "do it for you", as you won't learn anything other than how to take credit for other people's work).
Something that I've heard over and over, but never really did, myself, until a few years ago, is "Write the documentation first". Open Microsoft Word (or a LaTeX editor, or whatever else you like to use) and spend an hour writing yourself a detailed document of the problem. This usually forces you to see relationships between the pieces, as well as how to organize a complex problem into a series of simple steps.
One thing that few beginners seem to recognize is the power of the sub-VI. Usually the problem can be broken down into a few "big pieces" -- write each piece as its own sub-VI, with inputs and outputs as connectors. A common LabVIEW (if not Best, then at least Pretty Good) Practice is to use the 4-2-2-4 Connector Pane (four inputs on the left, four on the right, two on top, two on the bottom, with Error In and Error Out on the lower corners), even if you have only a single input and output. Note that if you have, say, 7 inputs, this is a sign that maybe you should combine related wires into a Cluster.
Oh, yes, also make an Icon for your sub-VI -- doesn't need to be complicated ...
Here's an example -- note the connector pane, the Error Terminals, the icon. "What Happens in the Sub-VI Stays in the Sub-VI" -- your top level VI, where the overall logic of the program should be evident, doesn't have to deal with the "messy details" of how you "Combine Inputs", but can just reflect that you did combine them.
Once you've written the document, start laying out your VI and sub-VIs. When you have something that doesn't quite work, post it and we will try to help/teach you.

Modbus error code 6101 and framing error

Using the Vi's MB INIT and MB WR to monitor the registers of a Micro-Motion sensor but keep getting either Framing error 1073807253 or timeout 6101. The communication is RS232, 1 stop bit, RTU (8 data bits), 9600 Baud and the program reads 50 consecutive registers (Floating), timeout is set to 2000 ms. Usually the errors occur after about 5 minutes or so.

Hello Romain
Please find attached my Vi. I have reduced the amount of registers taht were originally read from 50 down to 20 and increased time delays which seems to have removed the error code problem.
However I still miss data, for example the temperature reading will be fine for a few minutes but then go to zero or a large number. The same thing occurs with other registers that are being read.
Thanks

RV220W DMZ not working and protocol 41 packets not forwarded

After fighting a brand new RV220W for hours I am just about giving up on it.
It does not forward anything the to the DMZ server including the IP protocol 41 packets needed for our IPv6 6in4 tunnel.
Nor does it send protocol 41 packets to the WAN.
TCP and UDP packets are only forwarded to the DMZ server if specifically done by a firewall rule.
CISCO support was not able to solve the problem after half an hour on the phone.
Factory resets and absolutely minimal configuration changes have been tried to no avail.
Firmware is 1.0.1.0.
The hairpinning problem as well as the weird time problem cause by ticking the daylight savings box has been observed as well.
Should I return this thing having learned that CISCO quality is a thing of the past ?
The Netgear WNDR3700 it was supposed to replace, due to the SNMP support found in this router, happily forwards packets at half the price.

Manually creating a firewall rule with protocol 41 in the backup config file and restoring it makes no difference.
(A new checksum for the configuration file may be generated by md5sum when the checksum line has been deleted)
Default should be to route all IP packets regardless of protocol number to the DMZ server, when DMZ is enabled. Now the router returns a ICMP port unreachable message to the WAN sender.
Update:
The problem is only present when the dual stack IPv4/IPv6 feature is enabled, so after all it may be a bug and not a design decision. Waiting for Cisco support to verify/advice on this.
BTW it is unbelievable, that the configuration file (plain text) saved by the backup function in the router cannot be read / used by Cisco suppport. They can only handle something which can be displayed in a browser (sic!)
Update 2:
Further testing has shown, that the option of forwarding of protocol 41 packets for 6in4 tunnels in any mode (IPv4 only or IPv4/IPv6) is randomly enabled. Sometimes suddenly working after 30 minutes. At other times not at all even after a reboot. Occasionally it has been working in both modes.
I have provided information about this to CISCO.
Cisco support has recognized this to be a problem of the current software 1.0.1.0 and is issuing a refund of the router.

Modbus Ethernet Slave coils and discrete inputs

Hi,
I'm having serious problems in the comunication of more than 16 bits for coils or discrete inputs.
In this forum i've read some few post about this matter, tried the possible solution but got nothing working.
Guess that there is some kind of limitation or error in the ModBus modules available at the NI Labview webpages.
The idea is very simple:
I want to be able to sent 32 bits of coils from the ModBus Ethernet Master to the slave and sent 64 bits of discret inputs from the ModBus Ethernet Slave to the Master.
Can someone please give me a push? Im' kind of newbie with the Labview and would apreciate if someone that had this problem resolved could guit me a hint.
My best regards, Jorge
Solved!

Hi Jorgelopes,
thank's for posting on National Instruments forum.
Can you tell me if you want to communicate with an automate or a computer.
If you do not tried between two computer I suggestion to make the test.
Can you send the VI with which you encounter this trouble?
Best regards,
Flo
