Omron 3F88L-160 - Overview of Compoway;F Communications

4-2
4-1 Overview of CompoWay/F Communications
The 3F88L-160/162 Cam Positioner has a communications port that conforms to Com-
poWay/F Type B. Through communications, the 3F88L-160/162 is capable of reading
and writing cam programs and parameters as well as monitoring the present cam angle
and Resolver speed.
Note CompoWay/F is OMRON’s standard protocol for serial communications. It provides a standard
frame format and commands based on the Factory Interface Network Service (FINS) used by
OMRON Programmable Controllers in order to facilitate communications between components
or between a personal computer and a component.
Note FINS is a protocol used for message communications between controllers on OMRON FA net-
works.
H Cam Positioner Communications
In communications between a Cam Positioner and a host CPU, communications capabilities differ de-
pending on the operating mode of the Cam Positioner.
