1. A forced ON or OFF is executed for only one operation cycle, and therefore has
a considerable effect on the SET/RST and self retaining circuits when the PLC is
running. Moreover, a forced ON/OFF result is retained for devices (Y,M,S) which
are not being driven by an OUT instruction, etc., in the program.
2. The C200 to C255 32-bit up/down counters and the high-speed counters have
counting directions.
3. Extended file registers stored in the EEPROM in the main unit.

[D, DD], extended registers [R, DR], and the extended file registers
[ER, DER]. The file register [D] and the index registers [V, Z] cannot be
monitored.
