Technical Description
FieldBusPlug / Issue: 03.2012
Usage in Draw-Out Systems
The withdrawable technique is often used in industries where the highest availability and shortest down-
times are required. In the event of an error in a drawer, the replacement with a spare drawer shall be made
as fast as possible. UMC100 has several unique features supporting its use in drawer systems:
•The separation of FieldBusPlug (bus node) and UMC100

•In draw-out installations the UMC100 is usually mounted inside the drawer whereas the FieldBusPlug
is mounted in the cable chamber. This ensures that no trunks are required but a straight bus line can be
implemented. A very stable bus communication even at high baud rates is the result!
•In the event of a drawer replacement the FieldBusPlug stays active and sends a diagnosis message to
the control system that the UMC100 is missing. Even more important - the fieldbus address is stored in
the FieldBusPlug. If a new UMC100 is connected the old bus address is automatically used. There is no
need for setting a new address! See parameter Address Check for additional details.
All necessary auxiliaries required for the installation are available. See the diagram below on how to use a
PDP22, MRP21 or COP21 in a drawer system. The example shows PDP22 for PROFIBUS.

 FieldBusPlug and accessories in a draw-out installation. The fieldbus node is outside
the drawer so no drops are required.
 UMC100 and FieldBusPlug
can be mounted separately.
The FieldBusPlug contains the
