Allen-Bradley Ethernet Driver
l Is the channel using a serial or Ethernet driver?
l Does the driver read tags in separate requests, or are multiple tags read in a block?
l Have the device's Timing properties (such as Request timeout and Fail after
x
successive timeouts)
been optimized for the virtual network's communication medium?
Device Properties - Identification
Name:User-defined identity of this device.
Description: User-defined information about this device.
Channel Assignment:User-defined name of the channel to which this device currently belongs.
Driver:Selected protocol driver for this device.
Model: The specific version of the device.
ID: The device ID is the network address of the PLC.
Device Properties - Operating Mode
Data Collection:This property controls the device's active state. Although device communications are enabled
by default, this property can be used to disable a physical device. Communications are not attempted when a
device is disabled. From a client standpoint, the data is marked as invalid and write operations are not accep-
ted. This property can be changed at any time through this property or the device system tags.
Simulated:This option places the device into Simulation Mode. In this mode, the driver does not attempt to com-
municate with the physical device, but the server continues to return valid OPC data. Simulated stops physical
communications with the device, but allows OPC data to be returned to the OPC client as valid data. While in
Simulation Mode, the server treats all device data as reflective: whatever is written to the simulated device is
read back and each OPC item is treated individually. The item's memory map is based on the group Update
