7-3. BUSES
7-3.1. General
To open the Buses dialog box (see Figure 7-2), select the Buses tab in the setup screen.
This screen displays the communication channels to the peripheral devices in use in the controller.
Regularly, these are TCP/IP buses in use in the 8-port CommVerter for communication with pumps
and RS-485 linked devices.
In this screen, define buses to a list of available communication protocols (New procedure) or
update the link (Modify procedure). Figure 2-2 describes the setup of communication Buses. For
example, an OrPT with IP address 192.168.1.211 and port 3000 is connected to the SiteOmat,
requires defining an OrPT Bus channel identified by IP and port 192.168.1.211:3000.
When defining an OrPT device in SiteOmat, that OrPT is bound to the pre-defined OrPT Bus.
In the example below (see Table 7-1), each OrPT device is linked to a dedicated Bus channel. The
TLG console is bound to a dedicated Bus channel, and the dispensers (pumps) to another dedicated
Bus channel.
Table 7-1. Bus Definition Example
Device IP # Port
OrPT1 192.168.1.211 3000
OrPT2 192.168.1.212 3000
Printer1 192.168.1.211 3485
Printer2 192.168.1.212 3485
TLG 192.168.1.111 3005
Pump Server 127.0.0.1 2502
WGT 192.168.1.170 3000
MPI-C 127.0.0.1 2501
The pump server is an internal process in the OrCU, Therefore, the bus IP should be 127.0.0.1
(localhost).
When defining a communication BUS channel, it is recommended to have a convention of buses
names (related to the device name). Each bus name should have a unique name and continue with
the target device name, as shown in Figure 7-2. For further explanation see MDE 4820.
