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.
7.2 MONITOR MODE OPERATION
This section explains the procedure for monitoring the input [X], output
[Y], auxiliary relay [M], state [S], timer [T], counter [C], data registers
[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.
1. At the menu screen, use the [+] and [-]
buttons to move the cursor to the “Monitor/
Test” item, then press [OK] to display the
“device selection screen” shown at right. To
cancel the operation and return to the “top
screen (time display)”, press [ESC] at the
menu screen.
2. Use the [+] and [-] buttons to move the
cursor to the device which is to be
monitored. To cancel the operation and
return to the “menu screen”, press [ESC].
3. Press [OK] to display the monitor screen
for the device which was selected for
monitoring. To cancel the operation and
return to the “device selection screen”, press
[ESC]. After the power is turned on, the
number of the device to be displayed is shown as follows.
 The first time the power is turned on, the display begins with
device No.1.
 At subsequent power ONs, the device which was being monitored
at the previous operation is displayed (they are saved in memory
for each device type).
4. Use the [+] and [-] buttons to move the
cursor or the screen to the until the device
to be monitored is displayed.

7.5 TEST MODE OPERATION NOTES
1. When using multiple same-number timers (T) and counters
(C). Operation occurs as follows if multiple timers [T] and counters
[C] are used in programs which contain CJ instructions and step
ladders.
 When a setting change is performed after switching from the
device monitor to the test function mode, the setting change is
applied to the timer [T] or counter [C] which is nearest to Step 0.
 When changing the setting values for same-number timers [T] and
counters [C], use the programming tool to change the program.
2. When the set values of timers (T) and counters (C) are specified
indirectly. When the set values of timers (T) and counters (C) are
specified indirectly in programs, the values of indirectly specified
devices change if the set values of timers (T) and counters (C) are
changed in the display module.
3. When changing the values of extension file registers (ER and
DER). When the value of an extension file register (ER or DER)
is changed, such a change is counted as write to the EEPROM
memory. Be careful not to exceed the allowable number writes. The
allowable number of writes is 20,000 or less for the built-in memory
(EEPROM).
8. ERROR CHECK

14.8 TEST OPERATION ON SPECIFIED DEVICE
MONITOR SCREEN
To perform the test operation on the specified device monitor screen, it
is necessary to turn ON M in the system information (system signal
2). The device test operation is same as the operation in the monitor/
test mode.
15. SCREEN SAVER
The screen saver function displays the dedicated screen to prevent
burning of the screen when a key operation is not given for the
specified time in the display module. For the screen saver function, set
the screen saver setting time in “Doo+2” of the system information
(system signal 1). The screen saver function is set as 10 minutes as an
initial value in D8300, when “-1” or Doo +2 is “0”

When a key operation is not given within the specified screen saver
setting time, the dedicated screen shown below appears and scrolls
from the right to the left and from the top to the bottom. When a key
operation is given while the dedicated screen is displayed, the former
screen appears. The key operation given for the first time after the
dedicated screen appeared resets the screen saver function, and is
invalid as a key operation.

16.7 POINTERS FOR USING THE DISPLAY SCREEN
PROTECT FUNCTION
The display screen protect function settings should be specified in a
sequence program.
• The protect function is enabled by using the display module’s
“monitor/test function” to change the system information’s (system
signal 1) “Doo+3” current value to “1” or “2”.
• Once the setting is made, it cannot be canceled from the display
module.
• To cancel the setting, use the programming tool to change the
system information’s (system signal 1) “Doo+3” current value to a
value other than “1” and “2”. If the system information’s (system signal
1) “Doo+3” is set in a general purpose data register, however, the
display screen protect function can be canceled by turning the power
off, then on again.
17. OPERATION BUTTON ON/OFF
INFORMATION
Operation button ON/OFF information can be monitored at the system
information (system signal 2) “M +4 to M +7” while the PLC is
running. Various applications of this function are described below.
17.1 VARIOUS APPLICATIONS
1. Operation button function checks The programming tool can be
used to monitor the system information’s (system signal 2) “operation
button ON/OFF information”, to verify that operation buttons are
functioning properly.
2. Specified device monitor function device changes Devices
handled in the specified device monitor function can be changed
over by using both the “specified device monitor display status” and
“operation button ON/OFF information” in the system information
(system signal 2).

18. SPECIFYING A HEXADECIMAL
VALUE DISPLAY FORMAT
The procedure for specifying a hexadecimal display format for current
values which display at the “Monitor/Test” menu explained below. The
display format is specified by the system information’s (system signal
2) “Moo+8” ON/OFF status.
The display formats which correspond to the ON and OFF statuses
are shown in Section 18.1 below. The display format should either be
fixed as decimal or hexadecimal. Switching between the two should be
possible by an external operation.

*1. The setting value can also be changed when the PLC is in RUN mode.
19.1 WHEN A “FATAL ERROR OCCURRED” MESSAGE
APPEARS
Operation is possible with the “Level C” or “Level B” keyword function
restrictions. However, the system is probably in one of the statuses
described below. Check these statuses in the order shown below, and
take the appropriate corrective action.
1. Perform an error check at the display module, and if an error is
active, take the appropriate corrective action.
If a program error is active:
The fatal error was probably activated due to a program error. Use
GX Works2 to correct the program.
If no program error is active:
There may be a problem with the PLC’s memory content. Perform the
following procedure.
1. Use GX Works2 to perform a program memory all-clear.
2. Rewrite the program.
3. Stop the PLC, turn the power ON, display the “Error Check” screen
and check to refer to if the “Fatal error occurred” message appears.
 If the “Fatal error occurred” message appears, perform the
corrective action described at item “2” below.
 If the “Fatal error occurred” message does not appear, set the
PLC to a RUN state, then check again if the message appears.
If the message appears, a watchdog timer error has probably
occurred. In this case, the program should be re-examined.
2. If the “Fatal error occurred” message still appears after
performing the corrective actions described in item 1 above,
perform the following procedure to check for symptom
changes.
Turn the power OFF and disconnect expansion board connectors
Turn the power ON again at the main unit, display the “Error Check”
screen again, and check if the “Fatal error occurred” message appears.
1. If the “Fatal error occurred” message appears: The main unit
hardware may have failed. Contact Mitsubishi Electric at
Amzsuppor[email protected].
2. If the “Fatal error occurred” message does not appear: Turn the
power OFF, connect the extension devices, then operate the system
again to check for errors. If the problem persists, there may be main
unit or extension device hardware failure. Contact Mitsubishi Electric
at Amzsuppor[email protected].
