R/W items: RO: read only function; RW: read and write function
Special
M
Operates monitor NO contact (contact a). NO while RUN, contact a. This contact
M1000
is On while in the RUN state.
Operates monitor NC contact (contact b). NC while RUN, contact b. This contact is
M1001
Off while in the RUN state.
Initiates a forward (the instant RUN is On) pulse. Initial pulse, contact a. Produces
M1002
a forward pulse the moment RUN begins; its width = scan cycle
Initiates a reverse (the instant RUN is Off) pulse. Initial pulse, contact a. Produces
M1003
a reverse pulse the moment RUN ends; the pulse width = scan cycle
