error CIP communication connectionless

3 posts in this topic

hi all,

i have two NX1P2 writing data to each other, using CIPUCMMWrite instruction. Both of these instructions fail with error code 1C00 and extended 2000 8022, that tells me:

"The data type that is specified in the
request service data does not agree with
the tag information. The AddInfo Length
in the request service data is not 0."

I had done all checks on both programs (data type, setup as global variable, Publish only) and all is a expected in both plcs. Reading the manual  (W506) shows the data structure and objects involved in the communication, but is not clear to me how to check and modify the condition that made this particular error, besides CIPUCMMWrite seems an instruction that does not require any further handling of data. Others have met this particular error and how they solved it?

Many thanks

Can you post screen shots of your global variables and the CIPUCMMWrite instructions?

if you use the data type struct.
do the underlying data types match correctly?

Post screen of the instruction write the datatype formats and the global variable for better problem definition.
