How does mcgs control plc

You said to control the I input point of Siemens PLC, and then start the Q point, there are two ways to realize this, one is to input only the I point to the PLC, and then write the program in the PLC to let the I point and the Q point to be associated to start; the other way is to write the I point in the MCGS software to write down to the PLC, and at the same time to write to the Q point in the MCGS to be associated to the PLC as well, about the control of this. Suggest you use the script inside the software to realize it just fine
