Common Configuration Areas (Serial or Ethernet Device)
3.6. Common Configuration Areas (Serial or Ethernet Device)
The Edit Serial Port Configuration and Edit Socket Port Configuration pages have the following areas in
common. This section discusses the following:
•
•
3.6.2. Filtering/Data Extraction Configuration
•
3.6.3. Application TCP Connection Configuration
3.6.1. Ethernet/IP Settings
Use this area to set up the EtherNet/IP settings for a serial or socket port using the appropriate Edit Port
Configuration page.

Ethernet Transfer
Method
Specifies the Ethernet data transfer method used by the DeviceMaster UP. There are
three methods that the DeviceMaster UP can use to transfer data received from a
serial or Ethernet device to the PLC. These methods are:
•
Write-to-Tag/File - The DeviceMaster UP writes the serial data directly into a tag
or file on the PLC. However, it should only be used if the PLC can scan and
consume the serial data faster than the serial device can produce it.
•
Write-to-Tag/File-Synced - The DeviceMaster UP writes the serial data into a tag
or file on the PLC and provides a mechanism to synchronize the data flow between
the PLC and the DeviceMaster UP. Use this method when you want to ensure that
the tag or file is not overwritten before the PLC can consume the data.
•
Polling - The PLC requests data on a periodic basis. It provides the ability to
control the received data flow. However, it does require periodic data requests and
the request rate must be fast enough to ensure that the serial port receive queues
on the DeviceMaster UP do not overflow.
PLC IP Address
Specifies the IP address for the PLC EtherNet/IP card.
Note: The Polling method does not use this attribute.
PLC Controller Slot
Number
(ControlLogix
Family)
Specifies the slot number on the PLC where the controller resides. The slot numbers
typically start at zero for the first slot. This is only required for the ControlLogix
family of PLCs.
Note: The Polling method does not use this attribute.
