assigned a data block which is generated automatically. In the instance data block,
the values of the input, output and in/out parameters as well as the local block data
are stored.
Interface, Multipoint
→ Multipoint Interface.
Interrupt, Cyclic
→ Cyclic Interrupt
Isolated
In the case of isolated I/O modules, the reference potentials of the control and load
circuits are galvanically isolated from each other, for example, by optocouplers,
relay contacts, or transformers. The I/O circuits can be connected to a common
potential.The load memory is part of the CPU. It contains objects created by the
programming device. It can be either a plug-in memory card or an integrated
memory.
Contains the complete user program during runtime, the comments and the
symbolic system, additional special information which allows decompilation of the
user program, and all module parameters.
Local Data
→ Data, Temporary
Logic Block
In SIMATIC S7, a logic block is a block that contains part of the STEP 7 user
program. The other type of block is a data block which contains only data.
M
Manufacturer--specific interrupt
Can be generated by a DPV1 slave. The DPV1 master responds with a call of
OB57.
For detailed information on OB57, refer to the “System Software for S7-300/
System and Standard Functions” reference manual.
Measuring Range Submodule
Measuring range submodules are plugged onto the analog input module for
adapting to various measuring ranges.The multipoint interface is the programming device interface in SIMATIC S7. It
enables the simultaneous operation of a number of nodes (programming devices,
text display operator interfaces, and operator panels) from one or more CPUs.
Each node is identified by an address (MPI address).
MPI Address
→ Multipoint Interface (MPI)
N
Nesting Depth
A block can be called from another block by means of block calls. The nesting
depth is the number of simultaneously called logic blocks.
Network
In communications, a network is the connection between two or more
CPUs and other terminals such as a programming device, via a connecting cable.
Data are exchanged over the network between the connected stations.
Node Number
The node number represents the accessing address of a CPU or programming
device or of another intelligent I/O module when they communicate with each other
via a network. The node number is assigned by the CPU or programming device
using the STEP 7 software.
Non-Isolated
In the case of non-isolated I/O modules, the reference potentials of the control and
load circuits are electrically connected to each otherOrganization Block
OB Priority
The operating system of the CPU differentiates between various priority
classes, for example, cyclic program processing, process interrupt-controlled
program processing. Each priority class is assigned organization blocks (OBs),
where the S7 user can program a reaction. As a standard, the OBs have different
priorities to which they are processed when they occur simultaneously or when
they interrupt each other.
Operating State
The SIMATIC S7 programmable controllers recognize the following operating
states: STOP, STARTUP, RUN.
Operating System of the CPU
The operating system of the CPU organizes all functions and sequences of the
CPU which are not connected to a specific control task.
Organization Block (OB)
Organization blocks form the interface between the operating system of the
CPU and the user program. The sequence in which the user program should be
processed is laid down in the organization blocks.Variable of a STEP 7 logic block
2. Variable for setting the reaction of a module (one or more per module).
