3.3 Option handling without RESERVE modules
IM151-1 HIGH FEATURE interface module (6ES7151-1BA02-0AB0)
Manual, 03/2008, A5E01075975-02

Principle
The control and feedback interface is located in the input and output process image of the
PM-E 24..48 VDC or PM-E 24..48 VDC/24..230 VAC power modules. It can only be
accessed if entries ending in ...O or ...SO for that power module were selected in the
configuration software.
One bit is available for each ET 200S electronic module slot:
● Control interface: Slots 1 to 63
● Feedback interface: Slots 1 to 63

Figure 3-9 Control (PIQ) and feedback interface (PII)
Control interface PIQ (AB x to AB x+7):
You must inform the IM151-1 via the control interface about which modules actually exist
and which slots have been left out. The IM151-1 cannot evaluate the configuration until it has
received this information.
Table 3- 5 Control interface
Slot Value of the bit Reaction
0 Content of the bitspur is not relevant 0
1 Bitspur is valid
0 Slot does not exist in the actual configuration 1 to 63
1 Slot exists in the actual configuration
Feedback interface PII (EB x to EB x+7):
The feedback interface (8 bytes) tells you which module is actually located on which slot.
Table 3- 6 Feedback interface
Slot Value of the bit Reaction
0 Option handling is inactive 0
1 Option handling is active
0 Slot belongs to an option that does not exist or the module
status is not OK
1 to 63
1 Slot exists and is OK
If the feedback result of the feedback interface is identical with the specification of the control
interface, the configuration is correct.
