IO monitor for melsecnet

[sttchui 1]

HI Anyone can explain how the melsecnet can monitor the other station IO, & trigger an out output eg. Network work 1 Station 1 CPU02H QJ71BR11 QX41 QY41P Station 2 CPU02H QJ71BR11 QX41 QY41P Station 3 CPU02H QJ71BR11 QX41 QY41P Station 4 CPU02H QJ71BR11 QX41 QY41P Station 5 CPU02H QJ71BR11 QX41 QY41P How to configure the melsecnet if i wanted to monitor the IO from station 5 & trigger an output in station 4???

Typically devices on the MELSECNET network are mapped to B (bit) and W (word) addresses by the master. They are circulated around the network, and each station is assigned a range in the master. So for example, the master can write B0-B1FF, then the first remote can use B200-B3FF, and so on. Those addresses will be the same in all PLCs by default, so just look at the appropriate bits.
