Configuring Channel Selector Objects

To configure a Channel Selector object

1. In the Serial/Ethernet dropdown list, select any one of the options:

   • Serial (TBP): for direct serial communication with the device using Transparent Byte Protocol (TBP).

   • Serial (NITP): for direct serial communication with the device using Non-Intelligent Terminal Protocol (NITP).

   • TCP: to communicate over a TCP Ethernet connection.

   • UDP: to communicate over a UDP Ethernet connection.

     Both TCP and UDP use CAMP protocol for communication.

2. In the Block Size (Words) field, enter the maximum number of bytes that will be requested from the device in a single read operation.

   Note: You can type any value from 1 to 15. The default value is 7.

3. In the Write word bits (0=No/1=Yes) field:

   • Enter 1, to allow writing to the individual bits of a Word.

   • Enter 0, to not allow writing to individual bits of a Word.

4. In the Signed or Unsigned Value dropdown list, select the type of the register value.

5. In the Serial/Ethernet dropdown list if you select Serial (TBP) or Serial (NITP), the Serial Port section appears. Under this section,you can configure the direct serial communication settings:

   • In the COM dropdown list, select the COM port to which the target device is connected.

   • In the Baud Rate, Data Bits, Stop Bits, and Parity dropdown lists, configure the serial communication settings to match the settings that have already been configured on the target device.

6. Use Advanced option to modify additional communication settings. For more information see Advanced Settings.

   Note: If you are adding more than one device selectors to the same channel, except the Serial/Ethernet field you can leave the other fields blank.
