♦
When the unit is supplied, the terminating resistors are not switched
in!
♦
Please note that the bus termination is switched in only at the first
bus node (e.g. SIMATIC S 5/CP524) and last bus node (e.g.
CUPM)! When the matching resistors are being set, the electronics
box must be
isolated from supply
!
♦
Data transmission faults possible on the bus!
During active bus operation, the units with a
switched-in
terminating resistor must not be disconnected from supply. The
matching resistor when disconnected from supply (off-load) is no
longer effective because the terminating resistor obtains its voltage
from the connected unit.
The following illustration shows an example of the bus connection at
terminal strip X100 (Compact PLUS). If the connector at terminal strip
X100 of one node is removed, data transfer via bus is
not
interrupted.
The other nodes on the bus continue to be supplied with data via the
bus.
