When connecting multiple PLC with one COM port, many objects need to be created to communicate with different station numbers. Now there's an easy and fast way to reduce the number of objects used and shorten the time spent to design the Project.

Preset [Default station no. use station no. variable] to configure different station numbers with only a few objects using this preset station variable.

The setting is shown below:
In EasyBuilder Pro select Edit >> System Parameters >> Device >> Settings >> Tick [Default station no. use station no. variable] and select station variable in [PLC default station no.].


After setting, create the objects needed on editing screen, and simply input different values in LW-10000
to control different station no. PLC.

EX: Input "1" in LW-10000, this object will represent the address of station number 1. Values can be directly input on HMI. If input "10" in LW-10000, this object will represent the address of station number 10. Users are free to change and control the corresponding addresses.
