I/O Memory Appendix B
This area can be used to transfer information between Modules that does not required high-speed exchange.
The user can allocate the information to be transferred and the information can be used accessed from the lad-
der programs in the Coordinator Module and Motion Control Modules to coordinate programming.
Synchronous Data Link Bit Area: CIO 0200 to 0219
Each Module (Coordinator Module and Motion Control Modules) broadcasts up to two items (four words) of
data at the specified cycle. The data can be specified separately for each Module and is allocated for this area.
All of the linked Modules can access the data that is broadcast by other Modules.
Work Areas: CIO 0002 to CIO 0079, CIO 0140 to CIO 0199, and CIO 0220 to CIO 0255
(CIO 0002 to CIO 0099, CIO 0110 to CIO 0199, and CIO 0220 to CIO 0255 for Motion
Control Modules)
These words can be used only in the program; they cannot be used for I/O exchange with external I/O termi-
nals. Be sure to use the work words provided in the Work Area before allocating words in the Internal I/O
Areas.
Serial PLC Link Bit Area: CIO 0080 to CIO 0099
These words are allocated for use with the Serial PLC Link, for data links with a PLC.
• CIO 0080 to (CIO 0080 + No. of linked words
− 1): CJ1M to FQM1 Coordinator Module
• CIO 0090 to (CIO 0090 + No. of linked words
− 1): FQM1 Coordinator Module to CJ1M
Addresses not used for Serial PLC Link can be used only in the program, the same as the Work Area.
I/O Refresh
The ON/OFF status of external devices and I/O bits is updated during the I/O refresh. In doing so, the ON/OFF
status of external devices, such as pushbuttons, limit switches, photoelectric sensors, and other input devices
is reflected in the input bits in the I/O Area (CIO 0000). Also, the status of output bits in the I/O Area (CIO 0001)
is output to actuators and other external devices.
There are two methods that can be used for the I/O refresh.
END Refresh
With an END refresh, all I/O is refreshed once every cycle after the entire user program has been executed.
Inputs Outputs
The ON/OFF status of the external switch connected to the
built-in input terminal allocated to CIO 0000.01 is refreshed
once a cycle.
The ON/OFF status of CIO 0001.01 allocated to the exter-
nal device connected to the built-in output terminal is output
once a cycle.
