Debug system of circuit diagram of programmable logic controller (PLC) in e.g. steel plant, has PLC which debugs circuit diagram during execution of object control program based on variation order
Debug system of circuit diagram of programmable logic controller (PLC) in e.g. steel plant, has PLC which debugs circuit diagram during execution of object control program based on variation order
The debug system transmits the variation order which changes the connection state and connecting point of input and output sides to the PLC (2) from a programming apparatus (1). The PLC debugs the circuit diagram during execution of object control program based on the variation order.
