3.6 Other DP Slave Configurations
3.6.1 ET 200L and DP/AS-i Link
3.6.2 ET 200S
Introduction
Note
Configuring the Distributed I/O (DP)
When configuring the DP slaves ET 200L and DP/AS-i Link (distributed
I/O/actuator-sensor interface), the following applies:
• ET 200L can be expanded using Smart Connect (SC) a channel at a time
• DP/AS-i Link is configured with actuator-sensor interface slaves; see below.
When placing a DP/AS-i Link, a configuration table is displayed automatically in
which you can place the actuator-sensor interface slaves from the "Hardware
Catalog" window.
DP slaves and IO devices of the ET 200S family are configured like other modular
DP slaves and IO devices.
Special feature: Digital electronic modules with an address space of 2 bits initially
occupy 1 byte when they are inserted in the configuration table (Details view).
However, the occupied address space can be compressed after configuration by
means of the Pack Addresses button.
Example:
Before Packing
Addresses
After Packing
Addresses
Module I Address I Address
DI_1_Module 10.0 to 10.1 10.0 to 10.1
DI_2_Module 11.0 to 11.1 10.2 to 10.3
Addresses cannot be packed in the GSD-based variant of the ET 200S IO device.
In the HW catalog, use the variant that does not have a reference to a GSD file
(*.XML) in its info text.
