Outline

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.

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.
