Overview IO Section

The IO Configuration is an important part of TwinCAT. The simplest level of extension of TwinCAT is the TwinCAT IO level, which means that in the TwinCAT tree view there is the entry IO at any rate. After the respective configurations for various tasks have been carried out and all relevant variables are known to the IO section, the hardware - habitually a field bus with IO modules can be configured within the IO section. It is also possible to configure the IO section first and the other tasks later on.

Requirements

IO Devices

Configured input devices and configured output devices (field bus cards, NOVRAM, system interfaces, …) in the target system - local or remote - and their process images.

Mappings

Informations about mappings to other TwinCAT IO Devices or rather their process images.

Dialog "General"

The following dialog opens by double-clicking on "I/O" in the Solution Explorer. This dialog is only displayed if no target system other than the local system has been selected, i.e. TwinCAT is set to the local system.

Overview IO Section 1:

The dialog shows theTwinCAT IO Server of the local system. In the case shown, it is version 3.1 (build 2100) of the TwinCAT IO Server.

Dialog “Version [Target System]”

The following dialog displays the TwinCAT Server of the target system.

Overview IO Section 2:

In the image depicted above it is version v3.1 (Build 2003) of the TwinCAT IO Server.
