„ DIP Switch (SW3)
SW3 sets the operation modes such as transmission speed and the self-diagnosis system. The
pins are all set to OFF (right) before shipment.
„ INIT Switch
Normally, leave the INIT switch turned OFF. The 215IF Module will perform link communications or
the message communications with the settings in the MPE720 Module configuration definition.
At this time, the settings of SW1, SW2, SW3 (BRS0 and BRS1), and SW4 will be ignored.
Turn the INIT switch ON to operate the MP900-series Controller with the MPE720 using 215IF
Module communications, when the Module definition is not set or CPU memory is cleared.
At this time, message communications will be performed according to the SW1 and SW2 station
address, SW3 transmission speed setting (BRS0 and BRS1), and SW4 network address.
When the INIT switch is ON, link communications will not be performed, and data will not be relayed.
