![]() ![]() (A CJ1W-SCU41-V1 is already implemented in the field) on the slave'side i only have to make sure the variables are allocated on the right place, according to the master's commands and modbus' addresses, right? The only way to define my slave address is done by writing a code to put the value of the address on the corresponding bits of DM area? or can i define the address using some feature of CX-Programmer? I already read the "CS/CJ Serial Communication Unit Operation Manual" but i still have some doubts: I only have to work on the PLC' side and i only know the name of the variables and their corresponding address. At this moment I was asked to change one CJ2M's program (in Ladder, and the PLC is the slave) in order to make a list of desired variables "readable" by the master (an host computer/ SCADA) wich is using the protocol MODBUS-RTU.
