Hardware Configuration:
1. Link 2 LRD20RD024P1 as illustration show below.
2. Set left LRD in the illustration to master.
3. Set another LRD to Slave.

The communication parameter setting takes effect after power up again.
REMOTE IO FUNCTION
Up to 2 LRD units can be configured as Remote I/O nodes.
The Master can run its programming, but the Slave can’t. The Master writes its state of expansion output coil
Y to Slaver’s output coil Q. The Slaver writes its state of input I to Master’s expansion input X.
