Bits Name Function
n SR 230
00 RUN/STOP
Command
This bit is used to start and stop Customizable Counter Unit
operation from the CPU Unit. (Valid only when 00 Hex is
stored in bits 00 to 07 in word m allocated in the DM Area.)
OFF: STOP command (switches to PROGRAM mode)
ON: RUN command (switches to RUN or MONITOR mode)
Note If 00 Hex is stored in word m bits 00 to 07, the operating
mode at startup is determined by this RUN/STOP com-
mand. (The mode can be switched between RUN
mode and MONITOR mode from the Programming
Device connected to the Customizable Counter Unit.) If
anything other than 00 Hex is stored in word m bits 00 to
07, this RUN/STOP command will be ignored.
If the RUN/STOP command is enabled (i.e., 00 Hex is
stored in word m bits 00 to 07), the RUN/STOP Com-
mand Bit will turn OFF and the program in the Custo-
mizable Counter Unit will stop whenever the Load OFF
Bit in the CPU Unit (A50015) is turned ON.
