Controlling NWare controls

In order to work with NWare controls using an external protocol like RATC, each control must be assigned a control alias. Once an alias has been assigned, you can write values to the control and read values from the control via a TCP/IP or serial connection, depending on the protocol you are using.

Note: When you specify an alias, NWare will check to see if that alias is already in use by another control. If it is, a warning will be displayed. If you click Yes, the control alias will be moved over from the old control to the new control. If you click No, the alias will not be moved. If you want to control multiple controls using the same alias, assign the alias to one of the controls and then use control wiring to connect them together in the project.

The external control system connects to the node hosting the project in order to access its controls. The controls are available via all of the nodes used in the project, so you can connect to any node in order to access a control. For redundancy support, however, we recommended that, rather than using a single node to access all the controls, you arrange for your system to failover to an alternative node should the original become unavailable.
