Commissioning and Diagnostics
Configuration
The ET 200S has maximum address space of
• IM151-1 BASIC: up to 88 bytes for inputs and 88 bytes for outputs.
• IM151-1 STANDARD (up to 6ES7 151-1AA03-0AB0), IM151-1 FO STANDARD
(up to 6ES7 151-1AB02-0AB0): up to 128 bytes for inputs and 128 bytes for
outputs.
• IM151-1 STANDARD (up to 6ES7 151-1AA04-0AB0), IM151-1 FO STANDARD
(up to 6ES7 151-1AB03-0AB0), IM151-1 HIGH FEATURE: up to 244 bytes for
inputs and 244 bytes for outputs.
To better exploit the available address space of the DP master and reduce data
transfer between the ET 200S and the DP master, you can group several
electronic modules/load feeders in a single byte in the input or output area of the
process image. This is achieved by the systematic arrangement and designation of
the ET 200S electronic modules/motor starters.
In Appendix C you will find a table giving the address space required for the
individual modules.
You can group the following module types in a single byte:
• Digital input modules
• Digital output modules
• Motor starters (direct-on-line starters and reversing starters)
How to proceed with groupable modules using the DDB file
1. Integrate the device database file in your configuration software.
Result: In the hardware catalog of your configuration software you can
recognize groupable modules by the fact that they are available in duplicate.
The modules differ from each other only by a "*" in the designation.
2. Configure the ET 200S setup, adhering to the following rules:
-- The modules that you can group in a single byte must be of the same
module type (see above).
-- IM151-1 STANDARD, 6ES7 151-1AA00-0AB0 interface module with
product level 1 to 4: The modules that can be grouped within a byte must
be immediately adjacent. There can be only power modules between the
electronic modules. Power modules do not open a new byte.
-- As of IM151-1 BASIC; IM151-1 STANDARD, 6ES7 151-1AA00-0AB0
interface module with product level 5, 6ES7 151-1AA01-0AB0; IM151-1
FO STANDARD and IM151-1 HIGH FEATURE: Any other module types
can be inserted between the groupable modules.
