-251723760 CIP Error when trying to read and array of sgl from and AB ControlLogix PLC

Question

I have the NI Ethernet/IP module to communicate with an Allen-Bradley ControlLogix PLC. I am doing both reading (only 13 values) and writing (over 200 values). I am using the basic ethernetip tag write.vi to  do the writing. These program are in an executable running on a 'run-time' machine. I have the list of tagnames I am reading and writing to and have confirmed with the person who created the AB load that the array I am writing to on the AB side has more than enough addresses (it is an array of length 300). However I am only able to write 118 values to it. When trying to write 119 or more I get the error:
-251723760 CIP error - extended status may be available
I have confirmed with NI OPC Servers with an OPC quick client (running on my development PC) connected to the AB ControlLogix that the values I am writing to up to element 118 are getting through correctly, i.e. if I write 123.456 to sample_array[13] then I in fact see this same value at that location in the OPC quick client.
To be honest I am a little disappointed that the error message is so cryptic and gives no hints as to what troubleshooting paths are possible. I have tried various combinations of group/tag names with and w/o offsets, e.g. [3], but nothing has led me any further.

Answer 1

Thanks for the quick response - here are screenshots of before (write OK - writing 118 values - all except last are 0) and after (error - when trying to write an array of length 119) as well as the simple test program I as using.
