Communications
Control Method
Programs can be created in the host computer (e.g., a personal computer) to
set or monitor parameters in the S8AS. Therefore the descriptions in this sec-
tion are from the standpoint of the host computer.
CompoWay/F is OMRON's unified communications protocol for general-pur-
pose serial communications. This unified format has a proven track record
with OMRON Programmable Controllers, has FINS-compliant commands
(see note), and simplifies communications between the host computer and
components.
Note FINS (Factory Interface Network service) is a messaging protocol for commu-
nications between Controllers in OMRON FA networks.
The S8AS has the following communications functions:
• Reading settings and data
• Executing operation commands
• Switching setting levels
The following restriction applies to the communications functions:
• Settings data can be written only when writing is allowed through commu-
nications.
