Hi
I need to set up a comm loss heartbeat between a Siemens s7-200 226 plc (Slave) and a Siemens s7-300 314c-2dp PLC (Master).
They are communicating via wireless and i need to be able to have an alarm light come on at the s7-200 if the signal is lost.
I am still new to plc programming and would like some help on this.
Thanks
