Communications Procedure

60
CompoWay/F is a standard OMRON communications protocol for general-
purpose serial communications. It uses a standard frame format as well as
FINS commands that have been proven in data exchange between OMRON's
Programmable Controllers (PCs). The CompoWay/F format facilitates serial
communications between components or a PC and components.
FINS (Factory Interface Network Service)
FINS is a protocol for message communications between Controllers in
OMRON FA networks.
Note The program for communications is created on the host PC and E5ZN's parameters
are monitored or set from the host PC. In this manual, descriptions of communications
are given from the standpoint of the host PC.

Communications between the Temperature Controller and the host PC are
implemented on a frame-by-frame basis.
When the host PC sends a command frame to the Temperature Controller, the
Temperature Controller returns to the host PC a response frame that corre-
sponds to the command frame.
Command and response frames are transmitted as follows:
Host PC
Temperature Controller
Allow a minimum wait time of 5 ms from when the host PC receives the re-
sponse from the Temperature Controller until the host sends the next com-
mand.
