Master Reset of Slave PLC

[montyk]

I am using an MD2424 as a master controller and using it to set  and read varibles in eight MD888, using the hostlink commands with a RS485 loop and then they control the processes. But I have run in to a porblem were on of the slave MD888 will get bad data loaded into a varible which causes it's program to pause because of a data out of range alarm, if I reset the unit it starts to run again. Is there a command that the Master controller can send to the slave to cause a Master Reset in the slave unit when it can not communicate with the slave unit.

You can send the "CL" command to the slave to reset it.

Alternatively, in the slave PLC, add a circuit as follow:
      RLY1
|-----||---------------[MaRST]

This way you can turn on RLY1 in the slave to cause it to reset itself.
