Micro Memory Card (MMC)
Micro Memory Cards are memory media for CPUs and CPs. Its smaller dimensions
form the only difference compared to the --> Memory Card.
Module parameters
Module parameters are values which can be used to control the response of the
module. A distinction is made between static and dynamic module parameters.
MPI address
--> MPI
MPI
This interface is capable of multipoint communication (MPI). It forms part of the
SIMATIC S7 PG interface. it also offers optional multiple node operation (PGs, text
displays, operator panels) on one or several PLCs. Each node is identified by a
unique address (MPI address).
Nesting depth
One block can be called from another by means of a block call. Nesting depth is
defined as the number of simultaneously called --> code blocks.
Non-isolated
The reference potential of the control and on-load power circuits for non-isolated
I/Os is electrically interconnected.
OB
