The Relay Output Link node allows to communicate with the NET Link equipped with output boards. Please see more information in the chapter covering the NET Link.
The node configures the device and sends commands to it, for instance to close a contact.
The NET Link Input node might also be of interest for you.

IP and Port
Enter the correct IP address and port from the NET Link's processor or from the Calibration Link.
Reset To Factory Default
This buttons resets the above settings in the Widget Designer interface. To reset the device itself (to the IP address 192.168.178.222 and the port to 5000), hold the "Reset" button down whilst plugging the power into the device. Release the button again.
Connect / Disconnect
Before starting to communicate with the device, for instance receive data, the node must be connected to the device. The connection itself consumes no performance.
Change IP Address
This button opens a new dialog whereto you may enter another IP address and port for the device. Power-cycle the device to apply the changes.
A NET Link / Calibration Link is configured by coolux as you have ordered it. However, if you have changed some input / output boards, the processor must be configured in terms of giving him the information which boards are connected to it. Click the "Config Module" button to open a new dialog where you may choose the according boards per processor connection. Find more details in the NET Link hardware chapter.
Start Data / Stop Data
As soon as data is processed via the network from the device to Widget Designer, performance is drawn.
Store Last Transmission State to NET Link CPU
Click this button and power-cycle the device if you wish that it remembers whether it should (not) send data as soon as it is powered up.
Channel, Input list and State
First, connect an Input node or Filter node to the Relay node to provide the information "0" or "1". Then open the Item Properties and choose the incoming source data for the channel you like to control. The "State" informs you about the current state of the what the incoming signal. "0" leaves the contact open, whilst "1" closes it.
This node allows to be remote controlled via so called node commands. Node commands access functions from a node and / or set a parameter.
Enter "node", followed by the according ID and a dot and a list will pop up showing all available commands for the node. For instance, node1.StartData will execute the function automatically without the need of opening the Item Properties dialog and clicking the according button manually. node1.SetRelay,1,1 will set the first channel to the state "1".
In addition, the node properties with a parameter ID (the small superscript number) can be edited via the commands WDNodeSetParam,NodeID,ParamID,Value or nodeID.ParamID@Value.
