Mounting
The terminal modules that can be mounted on a DIN rail (35 x
15 x 7.5 or 15 mm) form the carrier system for the I/O modules.
They are used for the process wiring and enable the electrical
and mechanical connection of the I/O modules. The terminal
modules can be prewired and tested without the I/O modules.
The I/O modules are simply plugged in place later. Terminal
modules are available with screw connections, spring-loaded
terminals or FastConnect design for fast mounting.
The automatic coding of the I/O modules reliably prevents the
The automatic coding of the I/O modules reliably prevents the
risk of injury to persons and/or destruction of modules through
accidental mounting of the wrong module.
Expansion limits
Depending on the IM 151 interface module used, the expansion
of an ET 200S station is subject to the following limits:
• A maximum total of 63 I/O modules per station can be inserted
• A maximum total of 63 I/O modules per station can be inserted
between interface module and terminating module
• The maximum permissible width of an ET 200S station is 2 m
• The maximum address volume of all the inserted I/O modules
• The maximum address volume of all the inserted I/O modules
is 244 byte for input data and 244 byte for output data
• The maximum number of parameters is restricted to 244 byte
per station
ET 200S configuration
The SIMATIC ET 200 configurator can be used to compile an
ET 200S station rapidly and simply. It knows the configuration
rules, and supports selection of all components and associated
accessories in interactive mode. The SIMATIC ET 200 is avail-
able in the current CD-ROM Catalog CA 01 and on the Internet.
