IP Address
Address within IP (the Internet Protocol, part of TCP/IP).
An IP address consists of 4 decimal values. Each of these must be in the
range between 0 and 255. In the usual representation, these 4 decimal
values are separated by points.
netX
networX on chip, next generation of communication controllers
netX Configuration Tool
The netX Configuration Tool allows users to operate cifX or netX based
devices in different networks. Its graphical user interface serves as a
configuration tool for the installation, configuration and diagnosis of the
devices.
Modbus Data Model
The data model distinguishes four basic types of data areas:
• Discrete Inputs (inputs) = FC 2 (Read)
• coils (outputs) = FC 1, 5, 15 (Write and Read back)
• Input register (input data) = FC 4 (Read)
• Holding register (output data) = FC 3, 6, 16, 23 (Write and Read back).
It should be noted, however, that depending on the device manufacturer
and device type:
• the data area in the device may be present or not,
• and two data areas can be combined into one data region. For example,
discrete inputs and input registers can be a common data area, which can
be accessed with read-FC 2 and FC 4.
• Further FC 1 and FC 3 are used instead of reading back the inputs to read
the outputs.
Object Dictionary
An object dictionary is a storage area for device parameter data structures.
It is accessed in standardized manner.
Open Modbus/TCP
A communication system for Industrial Ethernet designed and developed by
Schneider Automation and maintained by the Modbus-IDA organization
based on the Modbus protocols for serial communication.
PCB
Printed Circuit Board, (printed = machine-made) circuit board
PCIe
Abbreviation for PCI Express
