PURPOSE:To facilitate confirming program execution conditions and setting and changing various data by executing modules in the execution order according with a command which individually executes modules and displaying the condition of execution of each module and freely changing execution contents of the module. CONSTITUTION:A control unit (BCT) 11 and plural input/output units (IOU) 21-2n are connected by a buas 1a1, and plural BCTs 12-1m are connected by a transmission line 31 and are connected to slightly long-distance BCT 1n and following BCTs through a data transmission line 32 and a repeating unit (REP) 4. Meanwhile, the data transmission line 31 is connected to a main data transmission line 6 from a main controller (MCT) 5 to each part through a gateway (GW) 7 having repeating and schedule control functions, and a portable operation display device (HMMI) 8 is freely connected and set to BCTs 11-1n, the GW 7, etc. Thus, commands and data to BCTs 11-1n and the GW 7 are very easily set and changed by data transmission and reception to and from an optional unit. |
