Communications interface configuration
The Server architecture module CommManager is responsible for exchanging
data between the FMDataManager module and external field devices such as tank
gauges and remote terminal units.
Note! Make sure that the
CommManager is not in Shutdown
mode. Otherwise, the user will not
be able to access the configuration
and maintenance dialog boxes.
To be able to access the Communications menu, the user must have appropriate
privileges (refer to the Security). In most configurations, operators do not have
access to communication interface configuration.
The communications interfaces and associated devices of the CommManager are
configured and maintained from the Communications menu found in the
Configuration application.
Configuration can include creating an interface, selecting a port, creating a device,
and establishing connections from the database points to the designated field
devices. The procedures for creating interfaces and devices vary depending on
the type of device you are using.
. An interface is utilized to transfer data into or out of a system. An interface is like a
communication channel, such as a serial port or network card. Some examples
include the Varec 8130 RTU, Modbus Master, Modbus Slave, and Varec TSU.
