Functions Included with Remote I/O Coupler Units

Windows driver (Win32 API functions) Windows PC, Ethernet, Remote I/O, User Application, Microsoft Visual Studio, CONTEC API Driver, Windows, F&eIT Protocol, Digital/Analog I/O

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 Windows PC, Ethernet, Serial communication, User Application, Microsoft Visual Studio, CONTEC API Driver, Windows, F&eIT Protocol, Serial Port

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.

COM drivers

Daisy chain connections Master PC,Ethernet, Ethernet, Ethernet

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.

Programmable Remote I/O Coupler Units (Software PLC Type)

CODESYS runtime that complies with IEC 61131-3 is built-in, allowing the use of a wide range of I/O modules.

(I/O module installation example)

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.

List of Products that Include CODESYS

Supported PLC Languages

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.

Functions Included with Programmable Remote I/O Coupler Units

I/O expansion using remote I/O CODESYS, Ethernet, RemoteI/O, RemoteI/O, RemoteI/O, RemoteI/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 Monitoring PC, CONPROSYS Gateway Series(HMIsoftware), Module1, Module2, Module3 Programmable Remote I/O, Devices

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.
