Configuring Communication Ports (Front Panel) - Omni 4000 Series Installation Manual

5. a. Confirm that any modules that
previously said N under the SW column
now say Y, indicating that their software
has been updated to reflect the hardware
installation.
b. Confirm that any modules that
previously showed N under the HW
column no longer appear on the screen
after the list has been updated, which
indicates that the module has been
removed.
In this example, the E-2 module
has been physically removed from
the flow computer, and after
performing the Check Modules

Configuring Communication Ports (Front Panel)

There are four protocols of communication for ports:
•
Modbus Slave Mode – a serial protocol that respond to requests from Modbus Master
devices.
•
Modbus Master Mode – a protocol that process transactions reading or writing from various
data types' Modbus slave devices.
•
Peer to Peer Mode – a serial protocol that allows several computers to be multi-dropped in a
serial network.
•
Active Redundancy Mode – a serial protocol that allows a pair of flow computers to operate
redundantly.
See Section 4.10.11 for configuring the flow computer in Peer to Peer or Active Redundancy
Mode.
Connect the flow computer to a serial port or Ethernet port PC if you have Serial or Ethernet
modules installed in the flow computer. You can alternately connect using the USB Mini-B port on
the front panel or as a backup, use the USB port on the CPU.
Use the PC that will host the OMNICONNECT software. For Ethernet connections,
the PC and flow computer need to be on the same network subnet if not
communicating through a router. Contact your network administrator if you need
help in determining the network address of the PC.
