2 Functions of Devices in DVP-PLC 2.11 Functions of Special Auxiliary Relays and Special Registers Function Group PLC Operation Flag Number M1000 ~ M1003 M1000: M1000 (A contact) is constantly “On” during operation and detection. When PLC is in RUN status, M1000 remains “On”. M1000 Y0 PLC is running Keeps being On Normally On contact in PLC RUN M1001: M1001 (B contact) is constantly “On” during operation and detection. When PLC is in RUN status, M1001 remains “On”. M1002: M1002 is “On” during the first scan when PLC starts to RUN and remains “Off” afterward. The pulse width = 1 scan time. Use this contact for all kinds of initial settings. M1003:
M1003 is “Off” during the first scan when PLC starts to RUN and remains “On” afterward. M1003 enables negative-direction (“Off” immediately when RUN) pulses.
