7.2 Response of analog output module
Display
The channel status LEDs are not affected by PROFIenergy.
Response to error detection
All channels that are in pause mode on "PE_MODE_PROCEED" report their diagnostic status as
in productive mode.
The following conditions apply to all channels which switch to the pause mode
"PE_MODE_SHUTDOWN":
•
"Wire break" and "Short circuit" error detection is not possible during the pause:
– Alarms for errors already pending before the "pause" are retained.
– Incoming and outgoing errors are reported once the "pause" has ended.
The following applies for all channels which switch to a different pause mode:
•
"Wire break" and "Short circuit" error recognition is possible during the pause. These errors
are reported.
• The selection of an incorrect pause substitute value which does not correspond to the
output range may result in the message "High limit violated" or "Low limit violated". The
pause substitute output value effective at the channel is limited to the high or low control
limit for the output range.
Mode parameter
The following table shows the "Mode" parameter.
Table 7- 1 Mode parameter
Element Code Explanation
Mode 0
D
: PE_MODE_PROCEED Proceed at "pause"
•
Value status "GOOD"
1
D
: PE_MODE_SHUTDOWN Switch off at "pause"
•
Actuator supply U
A
switched off
• Outputs de-energized
• Value status "BAD"
3
D
: PE_MODE_LAST_VALUE Last value at "pause"
•
Pause substitute value: Last output value:
• Value status "BAD"
4
D
: PE_MODE_SUBST_VALUE Substitute value at "pause"
•
Pause substitute value: Configured pause sub-
stitute value
• Value status "BAD"
1
As there is only one actuator supply U
A
for all channels, the supply can only be switched off during
a "pause" if all channel parameters have been set to switch off.
