SIDOOR functions
3.1 Basic functions
Prioritization of door command sources
Door commands can be issued via different sources. A higher-priority drive order overwrites
a lower-priority drive order. The service interfaces generally have the highest priority
because they are intended for commissioning and service purposes.
Table 3- 6 Prioritization of door command sources
Priority Door command source
High 1. Service buttons S401, S402 and S403
2. Software Kit (PC) and Service Tool or local
terminal
3. Process data
(USS, PROFIBUS, PROFINET)
FBLOCK system
(digital INPUT1, 2, 3, 4 and X5)
Low 4. FBLOCK system
(edge-controlled drive orders "latched")
Mutual prioritization of door commands
When a command is issued via the process image, there can be no mutual prioritization of
door commands because the corresponding DCMD signal is based on an enumerative
structure and therefore only ever one door command can be active. Prioritization is applied
in the case of interconnections within the FBLOCK system or the service buttons, for
example.
Table 3- 7 Prioritization of the door commands
Priority Door command
High 1. Stop
2. Open
3. Close
4. Automatic AssistedDrive,
Automatic ImpulseDrive,
Positioning
5. Learn run
Low 6. Deenergize

Remarks
Commands issued locally on the controller
Commands issued locally via the service terminal or the
PC tool
Drive orders are mutually prioritized
Only in the case of edge-controlled digital input signals of
the FBLOCK system (latched drive orders)
Remarks
The source voltage brake is deactivated after the ramp stop via the "special"
expansion bit
→ coasting down/deenergized with highest priority
Same priority
(internal processing sequence determines the drive order)
Learn run can be interrupted
Neutral door command corresponds to the idle state, equivalent to inactive
→ coasting down/deenergized with high priority via "special stop" drive order
