These coils are then moved into word 40100 using the simple instruction [...]

38 Contents Addressing Pay careful attention to the dip switch address configuration. EACH 1560-MBP on the network must ha ve it o wn unique address. This MUST also be diff erent from the PLC address. ALL drives should in general have their Host address set to the PLC ís address. Hints Note that the Stop bit is set to 1 to stop drive.
