CIO Area

Overview

It is not necessary to input the “CIO” prefix when specifying an address in the CIO Area. The CIO Area is gen- erally used for data exchanges, such as I/O refreshing between Modules (Coordinator Module and Motion Control Modules). Words that are not allocated to Modules may be used as work words and work bits in the program only.

Note The above figure depicts the CIO Area of the Coordinator Module. For the Motion Control Module, the following area ranges are different.

•Serial PLC Link Bit Area: Not provided

•Cyclic Refresh Bit Area: CIO 0100 to CIO 0109

•Work Area: CIO 0002 to CIO 0099

CIO 0110 to CIO 0199

The CIO Area includes the following four areas.

•I/O Bit Area

•Cyclic Refresh Bit Area

•Synchronous Data Link Bit Area

•Work Areas

•Serial PLC Link Bit Areas (Coordinator Module only)

I/O Bit Area: CIO 0000 and CIO 0001

These words are allocated to built-in I/O terminals the Coordinator Module or Motion Control Module.

Cyclic Refresh Bit Area: CIO 0100 to CIO 0139 (CIO 0100 to CIO 0109 for Motion Control Modules)

In the Coordinator Module, 10 words are refreshed every cycle for each Motion Control Module. These words contain Motion Control Module status, general-purpose I/O, and other information. (Refreshing these words is not necessarily synchronized with the Motion Control Module Cycles.)
