Configuring Read-Only Ethernet TCP/IP Devices
-
Set the Connect IP Address to the IP address of your Ethernet device.
-
Set Disconnect Mode to Never.
-
Optionally configure your Ethernet device to connect to the DeviceMaster UP at the DeviceMaster
UP IP address and Listen Port.
5.
Set up the socket packet identification.
a.
Set the Rx Timeout Between Packets. Set to zero to stream data with the Rx STX/ETX Detect settings set
to none. For normal settings, typical values are 10 to 50 ms.
b.
Set the STX (Start of transmission) Rx Detect in decimal format.
c.
Set the ETX (End of transmission) Rx Detect in decimal format.
d.
Enable the Strip Rx STX/ETX option if you do not want the STX and ETX bytes returned to the PLC or
application.
Note: Refer to your device's User Manual for the Start and End of Transmission byte(s) settings. You may
also be able to use the Ethernet Device Interface Logs page to determine these settings.
6.
Under Ethernet/IP Settings:
a.
Set Rx (To PLC) Ethernet Transfer Mode to Write-to-Tag/File.
b.
Set the PLC IP Address in xxx.xxx.xxx.xxx format.
c.
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.
