Hello,
I’m trying to communicate with the gateway AB9007 but i have errors in my project.
I don’t know where I do a mistake.
I get the MS light and the MTCP light flashing.
Can you help me ?
Thanks in advance.
It looks like you are using the wrong function code (2). Try using 3 or 4.
Also, can you translate the error code to English for me?
Thank you,
Kyle
I can’t use the function code 3 or 4 :
Oh sorry, I don’t seen the text is not translate.
Module unavailable.
Error.
Further informations for the module :
Differences have been detected between the configuration loaded and the project offline.

I’m not sure I understand. When you use function code 3 or 4 you get the error about exceeding the data size? You shouldn’t be getting that because you are only reading 7 registers. Are you changing the data type from bits to integers and the addresses to correspond to the registers and not bits? You also may need to try starting at address 0 instead of 1.
Sorry to disturb you, I find why my module had an error, like it’s said in the diag, the device name is not the same online and offline. I deconnect to my PLC and change the name of the Gateway in TIA Portal, and assign again the name.
Translation :
Module available.
Ok

This difference is accepted by the system, because the module plugged is not compatible with the loaded module."
After I try with only one world input and one world ouput. I noticed that the word input or output module must be in the same order as the mapping overview.
Thanks you !
Great! Let me know if you have any other questions.
