1.2 What is the ET 200U?
ET 200U is the designation for a slave station consisting of the following:
ET 200U interface module
Power supply
Bus units with up to 32 modules from the S5–100U I/O module spectrum.
The ET 200U distributed I/O station has the following characteristics:
IP 20 degree of protection
Accommodation of a maximum of 32 modules from the S5–100U module
spectrum (including CPs and IPs)
Maximum address space per ET 200U distributed I/O station
32 input bytes and 32 output bytes
Multi–tier configuration possible using the IM 315 and IM 316 interface
modules
Direct connection of a programmer or ET 200 Handheld for testing and
start–up (programmer with a CP 5410–S5DOS/ST programmer interface
module)
The station number of the ET 200U distributed I/O is switch–selectable
The ET 200U module, Order No. 8MB11 is operated with DP Siemens
( Section 1.3)
The ET 200U module, Order No. 8MB12 can be operated either with DP
Siemens or with DP Standard ( Section 1.3)
ET 200U module, Order No. 8MC11 can be operated either with FMS or
with DP Standard ( Section 1.3)
High data throughput:
20 ET 200U distributed I/O stations with 8 input bytes and 8 output bytes
(= 2560 bits of user data) are connected to the bus. The baud rate set is
1500 Kbaud:
I.e., a complete data cycle lasts 5.9 ms. During the data cycle the IM 308–B
master interface module and the distributed I/Os exchange input/output data.
