3.5.3.3 Interface monitoring
Interface monitoring is a congurable functionality introduced in rmwares 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 its 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. Its furthermore based on a
user-denable 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 dened:
• Exit remote control
• In case the DC input is switched on, it either switches it off or leaves it on, as dened by the parameter DC input -> State
after remote (see
3.4.3.1
)
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
3.4.3.6
), so these two timeouts can overlap
