saeedplc Posts: 288 Rating: (4)	thanks you for the reply dear umencho. as i told the network 1 work without any problem and whenever i need a toggle bit i use only this network. my main question is that why when i use m10.0 in s and r pins of flip flop it doesn't work but in network 1 i use q0.0 and it works! best regards.

If code is splitted in two separate networks, it can even be represented in FDB. A M 10.0 //Toggle command AN Q 0.0 //Set output S Q 0.0 R M 10.0 //Reset command bit A M 10.0 //Toggle command A Q 0.0 //Reset output R Q 0.0 R M 10.0 //Reset command bit Kind regards, BV
