CPU Overview
Outstanding Connectivity and Compatibility
J CS1 Offers More
More serial communications ports, more protocols. Up to 34 port connections with protocol setting for each port.

Data transfer protocol for serial communications vary with the manufacturer and
with devices. Differences in protocols can make communications between devices
by different manufacturers very difficult, even when electrical standards are the
same.

OMRON’s protocol macros solve this problem by:
• Enabling easy creation of protocol macros designed to match the protocol of a
connected device.
• Allowing you to communicate with essentially any device having an RS-232C,
RS-422, or RS-485 port, without having to write a special communications
program.
J The Two Main Functions of Protocol Macros
1. Creating Communications Frames
The communications frames can be easily created
according to the specifications required by the con-
nected device. Data from I/O memory in the CPU can
be easily included as part of a communications frame
to read from or write to I/O memory.
2. Creating Frame Send/Receive Procedures
The required processing, including sending and receiving
communications frames, can be performed one step at a
time according to the results of the previous step, and
then CX-Protocol can be used to trace send and receive
data.

J Application Examples
Standard System Protocols
Data transfers with OMRON components can be easily
performed using standard system protocols. There is no
need to develop your own protocols in this case.

User-Created Protocols
Data transfers with non-OMRON components can be easily
created just by defining parameters using the CX-Protocol
Windows tool.
