Operator controls and indicators
The digital outputs are provided for high-speed camming functions. They can be
programmed with technology functions in the STEP 7 user program. Digital inputs can be
used with technology functions such as reference point acquisition (reference cam) as well
as with technology functions in the STEP 7 user program.
You use the integrated inputs and outputs for applications in which rapid technological
processing is of prime importance.
If you wish to evaluate other inputs and outputs in the STEP 7 user program, they can be
interconnected in the usual way by means of supplementary input/output modules.

Slot for the SIMATIC Micro Memory Card (MMC)
A SIMATIC Micro Memory Card (MMC) is used as memory module. The MMC is used as
load memory and as a transportable data medium.
Note
Because the Technology CPU does not have an integrated load memory, you must plug in
an MMC to operate it.
You require an MMC, 4 MB and larger; for an operating system update you require an MMC
with 8 MB.
