CPSN-MCB271-S1-041
A wide range of I/O modules can be used as remote I/O for communication devices which include Modbus master functions.
This library software provides commands to Contec measurement control devices via an OS standard API.

Windows driver (Win32 API functions)
Use the driver library that can be downloaded for free from the Contec HP to create digital or analog signal I/O that is connected to the remote I/O in the same way as a program for a Contec expansion card. Linux drivers are also provided for free.
Virtual COM functions
Use the virtual COM drivers that can be downloaded for free from the Contec HP to access the remote I/O serial port as a Windows COM port.
Daisy chain connections
When there are multiple remote I/O configured on the network, the remote I/O terminals can be connected in a daisy chain, eliminating the need for a network branching hub.
Remote I/O using Modbus
An industry standard Modbus protocol is included, allowing the I/O module of devices that support Modbus master functions to be used as remote I/O.
CODESYS runtime that complies with IEC 61131-3 is built-in, allowing the use of a wide range of I/O modules.
CODESYS runtime is built-in. This makes it possible to execute IEC-61131-3-compliant PLC programs that were developed in the CODESYS integrated development environment.
A total of 6 languages are supported: 5 IEC 61131-3-compliant languages (ST, LD, FBD, SFC, and IL) and CFC. The object-oriented programming defined in the third edition of IEC 61131-3 is also supported.

I/O expansion using remote I/O
By using the CODESYS Modbus TCP master functions and connecting to the remote I/O-only couplers via the network and increasing the number of I/O points, it is possible to place the necessary I/O in the necessary locations and optimize the cable connections.
Module configuration using distributed control
In a system with a modular design, control of each unit with CODESYS allows a modular configuration that includes the wiring and increases the degree of freedom in system design.
