Configuring the Distributed I/O (DP)
3.6.3 ET 200S with Option Handling
Requirements for Option Handling
• Power submodule: PM-E DC 24V/AC120/230V or PM-E DC 24..48V/AC
120..230V with option handling (as of STEP 7 V5.3)
• Interface submodule: IM 151-1 STANDARD (6ES7 151-1AA03-0AB0) or IM
151-1 FO STANDARD (6ES7 151-1AB02-0AB0)
Overview of the Procedure
Rules
Option handling allows you to prepare the ET 200S for future expansions (options).
The following section provides overview of the function and procedure (for a
detailed description, see the ET 200S Distributed I/O manual):
1. Install, wire, configure and program the planned maximum configuration for
ET 200S.
2. Instead of using the electronic submodules that will be required later, use
economical RESERVE submodules (138-4AA00 or 138-4AA10) for the first
installation. The ET 200S can be completely prewired ("master wiring")
because a RESERVE submodule is not connected to the terminals of the
terminal submodule and thus is not involved in the process.
3. For those slots that will first be fitted with RESERVE submodules instead of
electronic submodules, enable option handling (in the property sheet for the IM
151-1 STANDARD, go to the "Option Handling" tab).
4. In the property sheet for the power submodule, reserve the required address
space in the process image output table (PIQ) and the process image input
table (PII) for the control and feedback interface by enabling option handling.
5. Later on, you can replace the RESERVE submodules with the configured
submodules without having to repeat the configuration procedure.
Option handling may be enabled for exactly one PM E-DC24..48V or PM
EDC24..48V/AC24.. power submodule.
Functionality: Option Handling During Start-up
If "Startup when defined and actual configuration differ" is disabled, then the
ET 200S will also start up if a RESERVE module is inserted instead of the
configured electronic submodule and option handling is enabled for the slot.
