Overview
The controller 751-9301(Compact Controller 100) is an automation device that
can perform control tasks of a PLC. It is suitable for mounting on a DIN rail and
stands out on account of its various interfaces. Among other things, the controller
has integrated digital and analog inputs and outputs and a serial onboard
interface in accordance with EIA-485/RS-485.
This controller can be used for applications in mechanical and systems
engineering, in the processing industry, in building and energy technology.
Automation tasks can be executed in all IEC 61131-3-compatible languages with
the CODESYS V3 programming system.
The implementation of the task processing in the runtime system for Linux
®
has
been optimized with real-time extensions in order to provide maximum
performance for automation tasks. Web visualization is also provided as
visualization in addition to the development environment.
For IEC-61131-3 programming in CODESYS applications, the controller provides
32 MB of program memory (flash), 128 MB of data memory (RAM) as well as
128 kB of retentive memory (retain and flag variables in an integrated NVRAM).

Two ETHERNET interfaces and the integrated, configurable switch enable wiring
in all necessary configurations with one common network where both ports share
a common IP address or with two separate networks where each port has its own
IP address.
The physical interfaces (ports) are assigned via logical bridges and can be e.g.,
configured via the WBM.
Both of these interfaces support:
•
10BASE-T / 100BASE-TX
•
Full/Half duplex
•
Autonegotiation
•
Auto-MDI(X) (automatic uplink and crossover switching)
The following fieldbus circuits are implemented for exchange of process data:
•
Modbus TCP Master/Slave
•
Modbus RTU Master/Slave (via RS-485)
CODESYS V3 makes configuring the fieldbus possible.
A Web-based management system (WBM) is also available as a configuration
aid. This system includes various dynamic HTML pages from which, among other
things, information about configuration and the status of the controller can be
