For communication between the PLC and your charger, I want to use RS232 communication. My system should work from midnight to 8 hours in the morning at full power. From 8 o'clock in the morning I want to disable the output of the load and after, for example, half an hour that it would automatically turn on the output of the load again. I need this to check the data of all systems that are connected to the PLC: a weather station, sensors ...and it will save energy because there is no need for work in this period of time.
I have 12 Siemens PLC systems. The proposed device is SmartSolar MPPT 75/15.
Is possible to set the timer on delay for the charger to turn off load output?
