PLC-499 Error code 0x0002 returned form PLC, this is the message that we receive when try to write a register to PLC Modicon 984, the read is correct for all register and bits work good for read and write. We tried several options by changing the parameters of the communication protocol and still the same. regards.

You are trying to write or read from an address that does not exist in the PLC. This happens when the Registers per message is set too high so that non-existing registers are accessed from a block read or write.
Reduce the number of Registers per message to 1 and see if this fixes the problem. If so, increase it as high as you can without getting the error on any screens.
