Note 1. “Operating mode changed” means between RUN or MONITOR mode and
PROGRAM mode.
2. The status of Timer Completion Flags and Timer PVs is held when the oper-
ating mode changes from RUN mode or MONITOR mode to PROGRAM
mode, but it is cleared when the operating mode is changed from PRO-
GRAM mode to RUN mode or MONITOR mode.
3. It is possible to set whether data in the EM Area is held or cleared in the Unit
Setup Area (bits 12 to 15 in DM 6600).
4. With the Customizable Counter Unit, there is no function (e.g., such as an
IOM Hold Bit) for holding the bit status in the cleared areas above when the
operating mode is changed or the power supply is turned ON.
