Interface module for ET 100U
The interface module for ET 100U, 6DS1 327-8AA, is a double-
height compact subassembly. The front panel width is 30.48 mm
(2 standard slots).

The module has 2 base plugs for the I/O bus interface and the
power supply, as well as a front plug (4-contact male connector)
with screw terminals for lines 1 and 2.

Mode of operation
Up to 3 interface modules 6DS1 327-8AA can be inserted into
any I/O bus slots in an AS 235 automation system. Each module
occupies several module numbers.

The interface modules adapt the I/O bus interface to the serial
SIMATIC S5 interface. In this manner, analog and digital input/
output modules of the ET 100U electronic terminator or the
S5-115U, S5-135U and S5-155U programmable controllers can
be connected to an AS 235 automation system.

If SIMATIC analog input modules are used, linearization of the
characteristic and compensation of the cold junction tempera-
ture must be carried out by the user for non-linear transmitters
and thermocouples.

ture must be carried out by the user for non-linear transmitters
and thermocouples.
Following application of the supply voltage after briefly switching
off the mode switch on the module and following elimination of
an interruption in the transmission cable on one of the two lines,
the interface module carries out a configuration operation in
which it stores an image of the connected SIMATIC S5 periph-
eral devices and used I/O modules in its main memory.

which it stores an image of the connected SIMATIC S5 periph-

The configuration data for the connected SIMATIC S5 expansion
units are determined by reading the configuration lists in the
expansion units, and for the ET 100U electronic terminator by
scanning the configuration EPROM submodule generated by
the user. The configuration data are the reference data for the
interface module.

The AS 235 automation system communicates with the
SIMATIC S5 peripheral devices via an intermediate memory on
the interface module. Both the automation system and the pro-
cessor of the interface module store transfer data in this mem-
ory.

entered by the automation system to the SIMATIC S5 output
modules and updates the input area in the intermediate memory
