Omron CQM1H-SCB41 CompoWay/F Master Protocol, System Configuration for Standard System Protocol

Appendix B

CompoWay/F Master Protocol

The CompoWay/F Master Protocol is used to send CompoWay/F commands with the CS1-series PC serving as the host (master).

CompoWay/F

CompoWay/F is a protocol used by many OMRON components for serial communications. A host computer of a PC can function as a host (master) to send CompoWay/F commands (message frames) to OMRON components, which function as slaves. The components will return responses to these commands. Using CompoWay/F com- mands, the host can read/write data, settings, and operating status to control the operation of the components.

CompoWay/F has the following features.

•The same message frame format is used, eliminating the need for special protocols for each component. The same commands can thus be used for serial communications with all CompoWay/F components.

•The CompoWay/F protocol conforms to OMRON’s standard FINS command protocol, providing compatibility with other networks and more flexible expansions in the future.

The CompoWay/F Master Protocol is provided as a standard system protocol to enable the CQM1H-series PC to executed read/write sequences for CompoWay/F commands.
