CIO Area Allocation
The memory allocation about communication services status in the CIO area
of PLC is shown as the following diagram. The beginning CIO channel m is
calculated by the following equation:
m = C 10×(0xFD - Unit Address)
The following table describes the unit address for each option port.
Service Status
!Caution
Bit 15 is used for detect power condition of PLC, so do not change it at any
time. Otherwise the CP1W-CIF41 Ethernet Option Board will generate error.
Error Status
The status of errors that occur at the Ethernet Option Board is reflected as
shown in the following diagram.
