3.5.3.3 Interface monitoring
Interface monitoring is a configurable functionality introduced in firmwares KE 2.06 and HMI 2.08. Its goal is to monitor (or
supervise) the communication line between the device and a superior control unit, such as PC or PLC, and to ensure that the
device wouldn’t continue working uncontrolled in case the communication line fails. A failing line can mean that it’s either
physically interrupted (damaged cable, bad contact, cable pulled) or the interface port inside the device hangs.
The monitoring is always only valid for one of the digital interfaces, the one being used for remote control. It thus means
that the monitoring can become temporarily inactive when the device leaves remote control. It’s furthermore based on a
user-definable timeout which would run out if not at least one message is sent to the device within the given time frame.
After every message, the timeout would start again and reset with the next message coming. In case it runs out, following
reaction of the device is defined:
•
Exit remote control
•
In case the DC output is switched on, it either switches it off or leaves it on, as defined by the parameter
DC output -> State
after remote
(see
Notes for the operation:
•
The timeout of the monitoring can be changed anytime via remote control; the new value would only be valid after the
current timeout has elapsed
•
The interface monitoring doesn’t deactivate the Ethernet connection timeout (see
3.4.3.5), so these two timeouts can overlap
