ET 200C Distributed I/O Station
EWA 4NEB 812 6119-02b
³
DP standard slave
Short name for draft standard DIN 19245, part 3
³
Slave station which behaves in accordance with draft standard DIN 19245,
part 3
E
The conductive soil where the potential at all points can be assumed equal to
zero.
Connecting an electrically conductive part to the earthing electrode via the
earthing system.
One or more conductive part(s) that make good contact with the earth.
All measures taken to establish a chassis connection.
Distributed I/O system from Siemens for connecting distributed I/O stations
to the programmable controllers S5-115U ... S5155U or any other adequate
master.
The ET 200 is characterized by fast response times as only small volumes of
data (bytes) are transferred. ET 200 is based on the PROFIBUS standard
(DIN 19245, part 1) and the draft standard PROFIBUS-DP (DIN 19245,
part 3).
ET 200 operates in accordance with the master/slave principle. The
IM 308-B or any host incorporating the CP 5480-DP can be master.
The distributed I/O stations ET 200B, ET 200C or ET 200U or other devices
not supplied by Siemens can be configured as slaves.
F
is a control command which is sent from the master to the slave.
The master uses this command to freeze the current states of the inputs. The
input data is then only updated again when the control command UN-
FREEZE is sent by the master.
