Enter the OPC server name in the device setup screen.
RSLinx Classic software must be activated at the OEM or higher level to support
OPC.
 Roll-up Server Communication Path
The communication path is simply the remote server's IP address or network name.
Other Communication Settings
The settings listed below apply only to certain device classes.
 Communication Timeout (seconds), Communication Retries, Maximum Messages
These parameters can be adjusted to improve communication on less than optimal
networks.
 Remote I/O Rack, Remote I/O Group, Remote I/O Scanner Slot
These parameters are used to configure pass-thru communication with child devices
on a Remote I/O network with a PLC-5 or SLC 500 parent device. The child devices
must be properly configured in the Remote I/O configuration of the parent device and
the parent device must be in ‘run’ mode for communication to occur.
 ADR Interface File
Applies to programmable controllers programmed to support automatic data
repopulation. Enter the address of the ADR interface file. The default is F100. If you
have changed the address of the ADR interface file in the ADR Wizard, enter the
correct address.
 Enable Communication Loss Alarm Check Box
Click this check box to have FactoryTalk EnergyMetrix software treat communication
loss to a device as an alarm condition.
The update rate of OPC devices can be configured in the System
Configuration page.
OPC devices utilize the Max Messages setting in the device setup.
There is no field for this on the device setup web page so it must
be changed manually in the database. If the field in the
database is null then it defaults to 10.
FactoryTalk EnergyMetrix software uses Remote I/O pass-thru
communication to connect to power monitor devices. If the
parent controller is communicating with the power monitor via
block transfer, care must be taken to schedule the programmed
block transfers to permit sufficient Remote I/O buffers and
bandwidth to support the pass-thru communication. If
communication errors occur with Remote I/O devices, check to
ensure that scheduled block transfers are not programmed to
occur continuously.
