Output → Analog output 1/2
Failure mode
• Min = Stored minimum value:
The stored minimum value is output.
• Max = Stored maximum value:
The stored maximum value is output.
• Fixed value = Constant value:
A constant value for output in the event of an error can be entered.
Output → Relay 1/2
Time delay
Setting the time delay for relay switching.
Operating mode
Operating mode of the relay:
• norm opened
• norm closed
Failure mode
• norm opened
• norm closed
NOTICE
Setting the limit relay failsafe mode
‣
The failsafe mode of the limit relay is configured in the setup. If an input to which a
limit value is assigned experiences an error, the limit relay assumes the configured
status. The effect of the limit relay in the event of an error must be specified in the
setup (energizes or de-energizes). If a failsafe mode with a fixed error substitute value
is configured in the input assigned, the corresponding relay does not react to the error
at the input. Instead it checks the substitute value for limit value violation and switches
depending on the limit value violation. The default value specifies that the relay is
energized.
Application → Calc value 1/2
Failure mode
• Invalid:
The calculated value is not valid and is not output.
• Fixed value:
A constant value for output in the event of an error can be entered.
Diagnostics
Verify HW set
If the hardware has been upgraded (e.g. contains additional relays, universal inputs etc.),
hardware verification has to be performed, i.e. the hardware is checked by the
deviceinternal firmware.
The Verify HW set function has to be activated in such situations.
Simulation
The output value of the analog outputs and the switching condition of the relays can be
specified in the simulation mode. Simulation remains active until it is set to "off". The start
and end of the simulation are saved in the diagnostic events.
