3.4.1   Device Properties

Device Name

A Device is a PLC, Controller, VAV or other automation hardware or software entity.  Device name is a User-assigned name that will appear in the Project Manager (Configuration Tool) and in runtime VIEW Displays.  Choosing a descriptive Name can help technicians identify the location of your device.

Changing only the Device Name will rename the existing device.

Changing both the Device Name and the Unit Number will make a copy of the device (e.g. create another device).

Description

User assigned description up to 70 characters

Unit Number

For some drivers (e.g. Modbus) this must correspond to the Unit Number used in the protocol addressing.  For some protocols (e.g. OPC and API), this can be any user assigned number. Please refer to the specific device driver guide.

This Unit Number will appear on the System Status Display, Point Detail, user-built displays and tags to reference the status of this device.

Changing only the Unit Number will change the existing device.

Changing both the Device Name and the Unit Number will make a copy of the device (e.g. create another device).

Device Type

This is the communication Driver used to communicate with all devices on this Com Port.  Only one communications protocol is supported on the same COM port. Once a Device Type is created on a COM port, the Device Type of additional devices will be limited to this Device Type.

To use another communications device, you must configure another COM port.  Multiple TCP/IP type Com Ports can be added which use the same TCP/IP Network Card on your PC.
