The CRI ethernet interface allows remote applications to connect to a robot controller: iRC, CPRog or the embedded control.

[[File:CRI-robolink.JPG|600px|CRI-Interface]]

'''The remote application can request the following operations:'''
* Jog the robot arm in joint space or cartesian space (base or tool coordinate system xyzabc)
* Send commands: joint motion, linear motion, digital outputs, ...
* Change variables
* Start and stop programs. These can be stored programs or the commands just send.

==Requirements==
* Using this interface requires programming experience in the client-server area.
* iRC / CPRog version V902-11-011 or higher
* Embedded Control with TinyCtrl version V980-11-087 or higher
* Updates can be found here: [[Software Updates]]

== Controlling a simulation via CRI ==
The CRI can be tested in simulation with iRC or CPRog. No real robot is needed.

=== Version 14 ===
In version 14 the CRI is always available and does not need to be enabled.

Since the iRC user interface itself uses the CRI to control the simulation your CRI client will be connected passively first and must be set active before sending commands (see section "Multi client support" in the CRI documentation). This will make iRC a passive observer. Click "Reset" in iRC to make iRC become active again.

=== Version 11-13 ===
In CPRog/iRC V11-007 to V13 the simulation can be controlled via CRI after enabling it in the backstage menu:
* "File" -> "Configure Interfaces" -> "CRI Interface"
* "Datei" -> "Schnittstellenkonfiguration" -> "CRI-Schnittstelle"

Click "Start" to enable the CRI server in CPRog/iRC. The status text will show the IP address and port that is being used. For local testing use the "Force IP address" checkbox and enter "127.0.0.1" into the text box.

Unlike V14 the user interface does not use the CRI and therefore does not become passive.
