Status information, general-purpose I/O, and other information for each Motion Control Module in the Cyclic Refresh Area of the Coordinator Module are refreshed every Coordinator Module cycle (asynchronous to the Motion Control Module cycles).

As shown in the following diagram, 10 words per Motion Control Module (5 output words and 5 input words) are allocated according to the Motion Control Module slot number (#1 to #4 in the following diagram) in the Cyclic Refresh Area of the Coordinator Module (CIO 0100 to CIO 0139).

Note Cyclic refreshing between the Coordinator Module and Motion Control Mod- ules is asynchronous. Information may take up to 2 cycles to be received.

5-3-2 Applications

In addition to the Synchronous Data Link Bit Area, normal data exchange between the Coordinator Module and Motion Control Modules is possible using the Cyclic Refresh Area.

Information for which high-speed data exchange between Modules is not required can be allocated anywhere, and a ladder program written for the Coordinator Module and Motion Control Modules to access these areas dur- ing operation can be created.
