[Enter]
.
The device responds with a status message. If an alarm or warning is
pending, the device sends the respective alarm or warning message to the
status query. Explanations of the status messages as well as alarm and
warning messages can be found in the Appendix.
8.8 Watchdog function
During a temperature control application in remote control mode, the watchdog
function monitors the active interfaces. In the event of a fault in the higher-level
data processing system, the watchdog function ensures that the device switches
to a previously defined safe operating status.
Cyclical data communication between the higher-level main computer and the
device is crucial. If data transmission is interrupted for a pre-defined period, the
watchdog function is activated.
Various conditions for safe operating status can be defined in the operating
menu:
• Mode: Specifies how the device should react when the watchdog function is
activated.
• Timeout: Defines how long data transfer from the main computer is
permitted to be interrupted before the watchdog function is activated.
• Setpoint: Defines the setpoint temperature that is activated to put the unit in
a safe state.
• Restart mode: Select whether the watchdog function should be reset when
only the setpoint temperature is received or upon all valid commands.
• Enabling/disabling warning. A warning message can be transmitted when
the watchdog function is enabled.
• Reset warning message: Here you can set whether the warning message is
reset manually or automatically.
