ET 200C Distributed I/O Station
EWA 4NEB 812 6119-02b
M
Module for distributed configurations. The IM 308-B master interface mod-
ule is used for “connecting” the distributed I/O to the programmable control-
ler.
Bus access method providing for only one
³
active node while all other
nodes are
³
passive.
All slave stations which are assigned to a master, together with the master,
form a master system.
is a slave parameter in COM ET 200. If a slave station is not addressed wit-
hin the monitoring time, all outputs will be set to ”0” (safe condition).
N
In non-floating I/O modules, the reference potentials of the control and load
circuits are electrically interconnected.
O
indicates the slave station for which a diagnostics message is present.
P
They may exchange data with an active node only after being requested to do
so by the active node (= slave station).
This is the master which is authorized to parameterize a slave station.
PROcess FIeld BUS, German process and field bus standard defined in the
PROFIBUS standard (DIN 19245).
It specifies functional, electrical and mechanical characteristics for a bit-se-
rial field bus system.
PROFIBUS-DP draft standard (DIN 19245, Part 3) on which the ET 200 dis-
tributed I/O system is based.
