Coupling with other systems
SIMATIC S5 I/Os / ET 100U
Interface module for ET 100U
Interface module for ET 100U
The interface module for ET 100U, 6DS1
The module has 2 base plugs for the I/O bus interface and the power supply, as well as a front plug
ET 100U electronic terminators, ER
The front panel of the interface module has a slot for inserting a configuration EPROM submodule. This is required when con- necting ET 100U electronic terminators.
Mode of operation
Up to 3 interface modules 6DS1
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
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
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.
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.
The processor of the interface module cyclically processes the connected SIMATIC S5 I/O modules, transfers the output data entered by the automation system to the SIMATIC S5 output modules and updates the input area in the intermediate memory by scanning the SIMATIC S5 input modules.
Data transfer between the interface module and the SIMATIC S5 peripheral devices is carried out in
The data are protected by 1 or 2 test bytes depending on the set transmission rate (cyclic BGH code).
If a plug on any SIMATIC S5 device is disconnected, the trans- mission line to the other devices is not interrupted (party line).
