Re: Auto off on slave when comm. is lost.

Subject:

Comments:: Example: Set up a clock pulse to get the master to periodically (says, every second) write to the timerPV[1] of the slave with a value of 50. Once this value is written to the timerPV[1] the timer #1 of the slave will start to count down. : If the RS485 is active, then the value for timerPV[1] will be reset to 50 everytime the master write to the slave via RS485 and will have no chance of timing out. : If within 5 seconds the slave did not receive any input from the master, the timer will time-out, so the slave can use the timer contact for timer #1 to shut off all the outputs. : : : Hello, : : I am using two T100MX 1616 PLC's. They are configured in a Master/Slave situation. My question is what is the simplest code to put on the slave that would make all outputs turn off if the RS 485 Communication is lost? : : Thank You, : : Ken Talley
