Which DP slaves
The following can function as DP slaves (passive stations):
can I use?
You can operate a maximum of 124 DP slaves in the ET 200 distributed I/O
system.
What can the
The SINEC L2 DP field bus transfers data at a maximum rate of 12 Mbaud,
SINEC L2-DP field
so reaction times are short. You can use either shielded two-wire cables or
bus do?
fiber optics to set up your SINEC L2 DP field bus.
The maximum range with copper cabling is 10000 meters; fiber optics extend
the range to 23 kilometers.
The bus connectors are of a design such that DP slaves can be linked to or
disconnected from the bus without interrupting data traffic.
Reaction time
The average reaction time of the SINEC L2 DP bus is approx. 1 ms under the
following conditions:

EWA 4NEB 780 6000-02a
ET 200B, a small, compact I/O station, degree of protection IP 20
ET 200C, a small, compact I/O station, degree of protection IP 66/67
ET 200M, a modular I/O station, degree of protection IP 20 for the use of
S7-300 I/O modules
