Handling Errors and Alarms Section 2-8
Alarm Flags
n = CIO 2000 + unit number x 10
ERC and RUN Indicators: Lit
The ERC and RUN indicators will be lit when an error occurs while the Unit is
operating normally. The following alarm flags will turn ON in CIO word n+9.
These alarm flags will turn OFF automatically when the error is cleared.
n = CIO 2000 + unit number x 10
Note 1. These alarms are output in word n+9 for CS1W-AD041-V1 and CS1W-
AD081-V1, and in words n+18/n+19 for CS1W-AD161.
2. The CS1W-AD041-V1 uses bits 00 to 08 of word n+9, and the CS1W-
AD081-V1 uses bits 00 to 04. The CS1W-AD161 uses bits 00 to 15 of word
n+18.
3. The disconnection detection function is enabled for input numbers set with-
in the input ranges 1 to 5 V or 4 to 20 mA.

EEPROM Writ-
ing Error
An EEPROM writing error has
occurred while in adjustment
mode. Holds the values
immediately
prior to the error.
No data is
changed. Turn the Set Bit OFF, ON, and
OFF again.
If the error persists even after
the reset, replace the Analog
Input Unit.
