Centralized Feedback Function; Bus Failure Function; Bus Or Mains Voltage Recovery Function - Panasonic WRKT4504E Series Reference Manual

Switching/Blind Actuator
The feedback cycle time can be set from Switch General page. If any of cycle feedback selection is
selected for each channel, the channel status is sent cyclically for cycle time. For the status format, if
any inverted selection is selected, the channel status is inverted and sent to bus.

4.1.3.9 Centralized Feedback Function

Centralized feedback function can be activated from Switch General page. The centralized feedback
object is a 4-byte object that stores the channel number and their status. The first 2-byte shows the
channel status as "1" (ON) or "0" (OFF). The second 2-byte shows howmany channel exits on the
switch module as "1" (EXIST) or "0" (NON-EXIST).

Byte-4
Byte-1 and Byte-2 show the channel status and Byte-3 and Byte-4 show the channel number in the
module.

Bus Failure Function

When the bus voltage fails there are three possible selections that the channel can handle:
 Unchanged: The channel status does not change.
 ON: The channel is switched on.
 OFF: The channel is switched off.
4.1.3.11

Bus or Mains Voltage Recovery Function

The bus voltage or mains voltage recovers the possible selections are grouped into two group:
 For Switch and On/Off Delay Functions:
o Like before failure: The channel status gets back to position that before failure.
o ON: The channel is switched on.
o OFF: The channel is switched off.
 For Pulse and Staircase Functions:
o OFF: The channel is switched off.
o Start pulse: The channel function is started according to the function selection (i.e. if the
channel function is Pulse then the pulse function starts, or if the channel function is
staircase then the staircase function starts).
