3.3.4 Configuring option handling without RESERVE modules
Introduction
You configure option handling without RESERVE modules as described below.
Procedure
1. Drag a PM-E 24..48 VDC or PM-E 24..48 VDC/24..230 VAC power module with one of
the following entries into the configuration table:
– ...O (option handling) or
– ...SO (status byte + option handling)
Note
You may only enter the power module with the ending ...O or ...SO once in the
ET 200S configuration!
2. Assign parameters to the interface module as follows:
Interface module Parameter Setting Description
Option handling,

Enable Option handling is activated for
the entire ET 200S.
IM151-1 HIGH

0AB0 and higher)

RESERVE modules
Note
If "Operation for set < > actual installation" is blocked for parameter assignment, the ET
200S does not start up if a module is missing or if an incorrect module is plugged in. The
diagnostic "No module" or "Incorrect module" is signaled.
If the IM151-1 does not start up in this state, the SF LED lights up at the IM151-1 and at the
deactivated electronic module of the ET 200S.
Note
In the case of option handling without RESERVE modules, incorrect filling in of the control
interface can result in too many plugged modules with a slot number greater than 63 are
reported from the point of view of the interface module. Since there is only room for 63
modules in the diagnostics message (module status), the highest-value bit is set in the
"Identifier-related diagnostics" in this case. This produces the following results:
- The SF LED on the IM lights up
- Bit 3 in status byte 1 of the diagnostics message is set (external diagnosis exists)
- The "Slot 64 faulty" error message is indicated in STEP7.
