Abstract

PURPOSE:To perform on-line/off-line switching operation with respect to a sequence controller SCT, by providing a switching means for a bus between the 1st microprocessor muPC and the 2nd muPC of the sequence controller SCT side. CONSTITUTION:In the on-line operation by an SCT21, an address bus switch ABSW7 and a data bus switch DBSW8 are turned on and an ABSW3 and a DBSW4 for a muPC1 and a memory 2 are turned off, putting the muPC22 of the SCT21 and terminal equipments 11-13 in operation. For the independent operation of the peripheral equipments in off-line mode, the ABSW7 and DBSW8 are turned off, and the ABSW3 and DBSW4 are turned on, putting the muPC1 and terminal equipments 11-13 in operation. Thus, the on-line/off-line switching operation as to the SCR21 is performed and more than one terminal equipment is connected.
