19.7 Monitor/Test Mode [Excluding User-Registered Devices]
19.7.1 Relevant devices
Monitoring and testing can be performed from the "Monitor/Test" menu for the devices listed below.
(Monitoring/testing is not possible for the file register (D) and the index register (V/Z)).
*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. Setting values of timer and counter can be changed when the PLC status is as shown below.
*3. The following setting changes are possible.
*4. The C200 to C255 32-bit up/down counters and the high-speed counters have counting directions.
*5. Enabled only when a memory cassette is installed.

The specified device’s current value
becomes the setting value.
With index modifier
[data register (D) + index register (V0 to
V7, Z0 to Z7)],
[Extended register (R) + index register (V0
to V7, Z0 to Z7)] The [directly specified device No.] + [index
register’s current value] becomes the
