Note
The error code (2 digits) that is output to AR 253 bits 00 to 07 is output.
CPM2C operating mode
Not used.
UM area write-protection (Mirrors the status of PC Setup setting in DM 6602 bits 00 to 03.)
OFF: UM writable
ON: UM write-protected
Not used.
CompoBus/S communications error (See note 1.)
OFF: Communications normal or not part of network
ON: Disconnected from communications
This bit will automatically be turned OFF if the slave joins the network again or the power
supply is turned OFF and ON.
ON when a non-fatal error has occurred.
ON when a fatal error has occurred.
Not used.
ON when a battery error has occurred.
(Effective only when detection of battery errors is enabled with the PC Setup setting in
DM 6655 bits 12 to 15 set to 0.)
ON when a cycle time overrun error has occurred.
Not used.
ON when FAL(06) was executed or a PC Setup settings error has occurred.
(The FAL number is transmitted in bits 00 to 07 of the leading word.)
ON when a memory error has occurred.
ON when there isn't an END(01) instruction in the program.
Not used.
ON when an I/O Unit over error (too many Units) has been detected.
Not used.
ON when an I/O bus error has occurred.
ON when FALS(07) was executed.
(The FAL number is transmitted in bits 00 to 07 of the leading word.)
1. This bit is supported from Units manufactured on June 1, 2009 or later. Re-
fer to page xxii for information on interpreting manufacturing numbers. Use
the manufacturing number to confirm that your Unit supports this bit before
attempting to use the bit.
2. If words in any areas other than the IR area (IR 000 to IR 227) or LR area
(LR 00 to LR 15) are allocated to the I/O Link Read area, the data may not
be cleared even when the power is interrupted, possibly causing data from
immediately before power interruption to be read by the master. If this cre-
ates a potential problem, use the following measures to eliminate the prob-
lem.
• When starting in RUN or MONITOR mode, configure the ladder program
so that the Read area is rewritten with appropriate data.
• When starting in PROGRAM mode, it will not be possible to take direct
measures at the slave. Monitor the status at the master and do not read
the data when the operating mode is PROGRAM mode.
