Omron C200HE User Manual

AR bits 0200 to AR 0204 correspond to the unit numbers of Remote I/O Slave
Units #0 to #4. These flags will turn ON if the same number is allocated to more
then one Slave or if a transmission error occurs when starting the System. Refer
to SR 251 for errors that occur after the System has started normally.

Bits AR 0205 to AR 0215 correspond to Group-2 High-density I/O Units and B7A
Interface Units 0 to 9 (I/O numbers) and will turn ON when the same number is
set for more than one Unit, when the same word is allocated to more than one
Unit, when I/O number 9 is set for a 64-point Unit, or when the fuse burns out in a
Transistor High-density I/O Unit. AR bit 0215 will turn ON when a Unit is not rec-
ognized as a Group-2 High-density I/O Unit.

Note Bits SR 28000 to SR 28015 also act as Error Flags for Group-2 High-density I/O

Units with unit numbers 0 to F.

AR 03 through AR 06 contain the Error Flags for Optical I/O Units and I/O Termi-
nals. An error indicates a duplication of a unit number. Up to 64 Optical I/O Units
and I/O Terminals can be connected to the PC. Units are distinguished by unit
number, 0 through 31, and a letter, L or H. Bits are allocated as shown in the fol-
lowing table.
