Replacing a Old version of Cp 341 to a newer version

[rj061991]

Yes the Original card is faulty and defective.. so we only transfer the dongle to the new one.. Probably next week we will try the MOdbus scanner to verify if theres a signal in the basler.. As of now,Only transmit signal Blinks...


I have attached the diagnostic buffer ..

Did you check the Modbus address of the Basler to make sure it is correct?

There is a discussion on this topic here:

PS: if your CPU 312 is of the older type that has a battery, check that your parameters for the Modbus send / receive blocks in your program are still correct (Modbus address, etc.)

in the Basler the address is 246.. whyl in the hardware configuration of simatic is 256 input 271 output

The CP 341 address in the hardware configuration is the hardware I/O address. It has nothing to do with the Basler Modbus address.
