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.
