Error confirmation
1.
Use the programming tool to call up the error code
2.
Check the error contents in the error code list of section
11.3.2 and 11.3.3 using the error code ascertained above.
11.3.1.1
Syntax Check Error
This is an error detected by the total
-
check function when there is a syntax error or
incorrect setting written in the program. When the mode switch of control unit is switched
to the RUN mode, the total
-
check function automatically activates and eliminates the
possibility of incorrect operation from syntax check errors in the program.
When a syntax check error is detected
ERROR/ALARM LED begins blinking.
Operation will not begin even after switching to the RUN mode.
Remote operation cannot be used to change to RUN mode.
Clearing a syntax error
By changing to the PROG. mode, the error will clear and the ERROR/ALARM LED will
turn OFF.
Steps to take for syntax error
Change to PROG. mode, and then execute the total-check function
while on-line with the programming tool connected. This will call up
the error contents and the address at which the error occurred.
Correct the program while referring to the error contents.
11.3.1.2
Self-Diagnostic Error

an abnormality in the system. The self-diagnostic function monitors the memory
abnormal detection, I/O abnormal detection, and other devices.
When the self-diagnostic error occurs
ERROR/ALARM LED begins blinking.
