8.9 Monitoring interface activities
In order to make the variables used within the application program accessible
from outside, several Ethernet servers are integrated in the JCM-631. These
servers support several protocols on different interfaces. The servers do not re-
quire any programming in the application program, but process requests from ex-
ternal clients on their own.
Monitored activities
The following interface activities can be monitored:
■
JetIP server via Ethernet interface
■
STX debug server via Ethernet interface
Purpose
The monitoring function for interface activities can be used, amongst others, for
the following scenarios:
■
Plants requiring process visualization to ensure safe operation. They can be
transferred into a save state if communication fails.
■
When the service technician connects an HMI, the application program auto-
matically displays additional status information.
