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 „Allgemein“

Folgender Dialog öffnet sich durch Doppelklick auf „I/O“ im Projektmappen-Explorer. Dieser Dialog wird nur eingeblendet, wenn kein vom lokalen System abweichendes Zielsystem angewählt wurde, TwinCAT also auf das lokale System eingestellt ist.

Overview IO Section 1:

Der Dialog zeigt denTwinCAT IO Server des lokalen Systems an. Im dargestellten Fall ist es die Version 3.1 (Build 2100) des TwinCAT IO Servers.

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.
