N
The node number represents the “access address” of a C7 CPU, C7 OP or a
programming or other intelligent I/O module when it communicates with
other nodes over an –> MPI network. The node number is assigned to the C7
CPU, C7 OP and programming device.
In non-isolated input/output modules, the reference potentials of the control
circuit and the load circuit are electrically connected.
O
The operating system of the C7 CPU organizes all functions and sequences of
the C7 CPU that are not part of a special control task.
P
1. Variable of a STEP 7 logic block
2. Variable for setting the behavior of a module (one or more per module).
Each module is supplied from the factory with a default setting that can be
modified using the STEP 7 tool S7 Configuration .
There are –> static parameters and –> dynamic parameters.
Parameter assignment refers to the setting of the behavior of a module.
In contrast to static parameters, dynamic module parameters can be modified
during operation by calling an SFC in the user program, for example, limit
values of an analog signal input module.
In contrast to dynamic parameters, static module parameters cannot be
modified by the user program. They can only be modified with the software
tool S7 Configuration, for example input delay of a digital signal input
module.
