hi fernando13, for two redundant inputs you don´t have to use both in PLC programm. Redundancy means that you have two HW-modules, one is active and the other is for backup. when the active one fails, the backup-HW is continuing the work on the point, where the other one dropped out. Both modules are connected to sychronize. There is one programm running one both PLCs that uses one address for a redundant HW. I recommend you to have a look into the S7400H manual. hope this helps, regards, |
