6.3 Errors and Countermeasures
6.3.1 CPU LED display messages
In the S10mini, if an event or error occurs, such a message as shown in the following table is
displayed on the indicator of the CPU module. The contents of display are distinguished
between the main module and sub-module of the IR.LINK.
In the S10V, error information is collected but an error is not displayed on the LPU module.
Collected error information can be referenced from the S10V BASE SYSTEM. For details, see
“6.3.2 Hardware errors” and “6.3.3 Communication errors.”

MDL Message Description Countermeasure
Main
module
IRLM @. @ The IR.LINK module (main module) was
started normally. This is not an error.
EX92 PTY A parity error was detected when the CPU read
data from memory in the IR.LINK module
(main module). If this message does not disappear
even after the CPU key switch has
been reset once and then set to the
original position again, replace the
IR.LINK module.
IRM □□□□ An error was detected in the IR.LINK module
(main module) board. See “6.3.2 Hardware errors.”
IRMN ○○○○ An error was detected in the IR.LINK module
(main module) network. See “6.3.3 Communication errors.”
IRMS
△△△△
An error was detected in the IR.LINK module
(main module) station. See “6.3.3 Communication errors.”
Sub-
module
IRLS @. @ The IR.LINK module (sub-module) was started
normally. This is not an error.
EX93 PTY A parity error was detected when the CPU read
data from memory in the IR.LINK module (sub-
module). If this message does not disappear
even after the CPU key switch has
been reset once and then set to the
original position again, replace the
IR.LINK module.
IRS □□□□ An error was detected in the IR.LINK module
(sub-module) board. See “6.3.2 Hardware errors.”
IRSN
○○○○
An error was detected in the IR.LINK module
(sub-module) network. See “6.3.3 Communication errors.”
IRSS
△△△△
An error was detected in the IR.LINK module
(sub-module) station. See “6.3.3 Communication errors.”
