SLC500_TCPIP object

The SLC500_TCPIP object is created from the New_PORT_TCPIP_000 branch of the Communication Driver hierarchy.

Add the SLC500_TCPIP object to your ABTCP hierarchy

1. Right-click on the New_PORT_TCPIP_000 object.

2. Select Add SLC500_TCPIP Connection from the shortcut menu. A New_SLC500_TCPIP_000 object is created.

3. Rename the newly created object as appropriate. The SLC500_TCPIP parameters view is displayed.

   Note: You can add up to 1024 of each type object to the hierarchy.

   • The SLC500_TCPIP object represents the logical endpoint to the hardware hierarchy.

   • The New_SLC500_TCPIP_000 Parameters configuration view is displayed.The SLC500_TCPIP parameters view is displayed.

The SLC500_TCPIP object is used to configure the SLC-500 processor on an Ethernet direct connection. This configuration view has four configurable elements:

• Host name: Host name or IP address of the destination.

  • The number of characters cannot be more than 255.

  • The field cannot be blank.

  • The host name is defined in the system host file (usually it is \WINNT\system32\drivers\etc\hosts).

    Note: The Host Name defaults to the LocalHost. If the LocalHost is selected and deleted, resulting in a blank Host Name field, and the Apply button is clicked on, an error message will appear.

• Data block size: The number of date bytes that can be sent in a message for this hierarchy.

  • For reading blocks:
    The default value is 510 bytes.
    The valid range is 2 to 510.

  • For writing blocks:
    The maximum writing block is 220 bytes, and not configurable.

• Connection timeout: The time allowed to establish a socket connection to a target device.

  • The default value is 2000 milliseconds.

  • The valid range is 1000 to 20000 milliseconds.

• Reply timeout: The time (in Seconds) the Communication Driver will wait for the acknowledgement after it sends out a message.

  • The message will be resent when time-out occurred.

  • The default value is 15.

  • Valid range is 1 to 300 seconds.
