The unique identifier of an instance for this device. This free-form name must be unique in the DDS and the FAC. That is, it must be a name not used by any other communication device, import/export device, remote device, or facility.

CygNet naming standards for device ID are as follows:

Displays a user-defined description of the remote device. A free-form description of the device. 32 character maximum.

Specifies the node number of the associated controller. The node for this device is 0 – 254 with 255 representing the broadcast address (as in TCP/IP).

For more information about SLC addressing, see the Rockwell Automation document SLC 500 Instruction Set Reference Manual (1747-rm001_-en-p.pdf).

The hex equivalent of the node.

Specifies the DF1 protocol by which to communicate with an associated controller. Options are Half-duplex and Full-duplex.

Check this box to retry the request in the event that the PLC is busy when the device is polled and receives an EOT (End of Transmission) packet.

Reads any data in the device response buffer and clears it prior to starting normal communication with the remote device when there is a queue of data waiting to be read. Applies only to half-duplex protocol.

The name of the communication device this remote device uses. Click the Options button to select from the choices in the drop-down menu. See Communication Devices.

This button provides several communications-oriented options.

Options are as follows:

• Browse: Enables you to browse to the Select Communications Device dialog box where you can choose a different communication device.
• Override settings: Enables you to access override settings for a TCP/IP MultiPoint communication device.
• Properties: Enables you to browse to the applicable communication-device properties dialog box.

Msg timeout (ms) displays the time in milliseconds a remote device waits for a valid response from an associated field device before timing out.

This setting is not the same as similar settings on the currently active communication device and device failover settings. But these settings work in conjunction with one another.

The number of times a remote device attempts to poll an associated field device until a valid response is received within the message timeout limit.

If a poll is successful, no more poll attempts are made. If a poll is unsuccessful, the remote device continues to attempt polls until a valid response is received or until the Poll attempts setting is reached, whichever comes first.

Click to access advanced communication device failover settings.

Select whether to enable or disable the device. The default setting is disabled. If an invalid configuration is detected, the device will automatically be disabled. The device can be re-enabled after the invalid configuration is fixed.

Defines the ACS security application name used to validate the users of this device. See Applications, Events, Permissions.

Defines the ACS security event used to validate users of this device. Click … to select the security event. See Applications, Events, Permissions.

Enables you to open a modeless Communications Data Viewer dialog box.

Enables you to view the audit trail for the device.
