The ET 200U is a slave interface module for the I/O modules of the
S5-100U.
The ET 200U distributed I/O station is compatible with both SINEC L2-DP
and SINEC L2- FMS.
The ET 200U is eminently suitable for applications requiring a large number
of locally installed inputs/outputs or modules from the S5-100U I/O range
(e.g. CPs and IPs).
The ET 200U consists of the IM 318-B or IM 318-C slave interface module
plus modules from the S5 I/O range.
The DP/AS-I Link connects the actuator-sensor interface to SINEC L2 DP. Its
degree of protection is high (IP 66/67), so the DP/AS-I Link is ideal for use
in harsh industrial environments.
One version of the S5-95U has an integrated interface for connecting the
S5-95U as a DP slave to the SINEC L2 DP bus.
The S5-95U with DP slave interface is suitable for applications which require
local intelligent signal preprocessing.
As of release status 3, the IM 308-C can be used as a DP slave in the
S5-115U, S5-135U and S5-155U programmable controllers.
This means, for example, that you can transfer data between two program-
mable controllers.
