Hi Amritpal, To use the counter operations within GRAPH, you would have to use the parameter type COUNTER. To use an IEC counter, as you tried to do and as I would recommend, you can follow the example from "CTU: Count up". Kind regards |

Hi Amritpal, You can either use counter operations together with the parameter type COUNTER, or you can program a call an IEC timer with CTU (or similar). You can't use counter operations with an IEC timer. Kind regards |

Hi Amritpal, To use the COUNTER parameter type, you must address a counter. This can be done by using it's absolute address, which is the letter 'C' followed by the counter number, e.g. C1 as in my example, or by using a PLC tag of type COUNTER. Kind regards |
