Communication AB9007


#1

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’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

Further information for the module :
Differences have been detected between the configuration loaded and the project offline.

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 !
