*13 All operations except the error handling are stopped. Yet dedicated instructions are processed on the condition that the
error does not affect the system (in case its error code (last 3 digits) is the numbers other than 800 to 859).
The signal output to the coincidence output 1 to 8 terminals (EQU1 to EQU8) or to the general output 1 to 8 terminals
(OUT1 to OUT8) is stopped.
Also, the updating of EQU1 to EQU8 terminal status (Un\G951), OUT1 to OUT8 terminal status (Un\G952), or CH1
External input status (Un\G1450) is stopped.
*14 Module ready (X00) turns off.
*15 "n" of the error code indicates the number (2 to 5) of the switch with the error.
• When another error is detected during the error occurrence, the information of the new error are overwritten in
CH1 Latest error code (Un\G1460) and in CH1 Latest error detection time (Un\G1461 to Un\G1464). Also, the
error log is stored in Error log (Un\G6010 to Un\G6164) in order of error occurrence. (For the error whose error
code does not have
, the error information is stored in both channels.)
• An error code can be reset by CH1 Error reset command (Un\G1480). Yet unless the error cause is removed, the
cause is detected again and the error code is stored.
