3. Select the module designation without "*" from the hardware catalog of your configuration
4. Select the module designation with "*" from the hardware catalog of your configuration
5. If a byte is filled, you must configure a module again (that is, open a new byte without "*").
No grouping
If you do not want to group digital input modules, digital output modules, or motor starters
within a byte when configuring the ET 200S distributed I/O system, use only those module
designations without "*" from the hardware catalog of your configuration software.
Each individual electronic module/motor starter will then occupy one byte in the input or
output area of the process image.

Note
In STEP 7 applications, if you combine the modules for IM151-1 STANDARD, IM 151-
1 FO STANDARD or IM151-1 HIGH FEATURE in the DPV1 mode:
• No insert/remove module interrupts (OB83) are triggered for these modules. In this
case, you can recognize that a module has been removed by evaluating the
module status in the diagnostic frame in the cyclic user program.
• Each grouped module then receives its own diagnostic address.

Result: You store other modules in the opened byte until all bits are occupied.
Note
Configuring by means of the GSD file:The configuration software does not check the
correct combination of the devices. If you configure more than 8 channels in a byte, the
modules that exceed the byte limit are reported as improperly configured in the
diagnostics:
Module status → 10 : wrong module; invalid user data
B
These modules are not addressed.
