Configuring Read-Only Serial Devices
6.
Set up the Ethernet/IP Settings.
a.
Set Rx (To PLC) Ethernet
Transfer Mode to Write-to-Tag/
File.
b.
Set PLC IP Address in
xxx.xxx.xxx.xxx format.
c.
If ControlLogix, set the PLC
Controller Slot Number. This
varies from zero to (max slot
number –1), but must always
be zero for CompactLogix. For
example, if the PLC has
seven slots, the slot number
range would be zero to six.
(This field is ignored for SLC/
PLC-5 PLCs.)
d.
If necessary, change the Maximum PLC Update Rate (Write-To-Tag/File) in seconds.
e.
If necessary, change the Maximum Rx Data Packet Size in bytes.
f.
Set Oversized Rx Packet Handling to Truncate or Drop, depending on your environment.
g.
Set the Rx (To PLC) Produced Tag Name for the PLC type.
ControlLogix PLCs: Set the Rx (To PLC) Produced Tag Name to the name of the tag where you want
the data placed. The tag must be an array of SINTs (bytes) large enough to hold the maximum sized
data plus four bytes for the sequence number and length fields. The maximum size is 444 SINTs.
SLC or PLC-5 PLCs:
•
Set the Rx (To PLC) Produced Tag Name to the file number where you want the data placed. This must be
an integer file or files in sequence large enough for the maximum sized data plus two integers for the
sequence number and length fields.
•
Set (PLC-5/SLC) Rx MS Byte First if you wish to receive data MS byte first (left to right in integer format).
7.
Set the Filtering/Data Extraction Configuration:
•
If no filtering/data extraction is required, leave all filtering/data extraction settings to defaults.
•
If filtering/data extraction is required, go to
Filtering/Data Extraction Configuration
8.
Set the Application TCP Connection Configuration.
•
If no application socket interface is required, leave all application socket interface settings at defaults
and verify that the Application Enable option is not selected.
•
If an application socket interface is required, go to
Application Socket Configuration
9.
Verify Reset Port and Save in Flash are selected and click Submit.
10. Optionally, save the settings in a configuration file using PortVision DX, which saves the network settings
and the protocol settings. You can use configuration files to upload the settings to multiple DeviceMaster
UPs or for restoration purposes.
a.
In PortVision DX, right-click the DeviceMaster UP in the Device List pane (lower), and click
Configuration > Save.
b.
Enter a file name for the configuration file (filename.dc) and click Save.
If all is set up correctly, the DeviceMaster UP places the data packets into the specified tag(s) or file locations.
The first integer received is the sequence number. This is incremented with each new data packet. The next
integer is the length, which indicates the number of bytes of data received. The rest is data.
