So the function you are looking for is the "stopwatch" function. It has an "enable" input which starts the counting. When enable is removed, the counting pauses. And with the reset input you can reset the value to zero again. So connect the signal that goes to your outputs to the en-signal of the stopwatch. Set the "Time Base" option to what you need (probably minutes, as seconds will overflow after about 8 hrs). You have to decide, when you want to reset the counter and if you need to store the runtime somewhere on the PLC (I normally use the "mathematics instruction" to store numeric results, just set the output to "last value" and set the en-input of that function high to read the input and to low again to store the value). than you need to decide what you want to do with the output. Put it in VM-Memory so it can be read with ModbusTCP, make it visible in the web interface and/or a display. It's all up to you. Attached you can find a simple solution.. best regards, Marco Attachmentlamp_counter.zip (362 Downloads) |
