SCADA Support
SCADA (Supervisory Control And Data Acquisition) is a term used widely in many industries
relating to monitoring and control systems. This section deals with the integration of the TReX
into a SCADA system. This is an optional feature, that requires a feature key to be purchased.
Terminology
SCADA application:
This is a software package that is used to control and monitor devices. This could be free open
source packages such as “Rapid SCADA” or “openSCADA”. Alternatively, this could be
industry standard applications such as “WonderWare” or “LabView”.
SCADA system:
This is a system comprising of one or many TReX units monitoring equipment that the TReX
units are connected to. This includes also the SCADA application.
MASTER:
This is the unit that is connected through Ethernet or another interface to a SCADA monitoring
application.
This master unit can now control and hold the details of up to 10 TReX slaves. Input and
output status of all units can be immediately requested or modified directly by the SCADA
application.
To set the TReX as a master set MENU->TELEMETRY->MODE to SCADA_MASTER.
SLAVE:
These TReX units are directly controlled by the TReX master. The slave’s primary function is
to report input changes and/or operate its outputs upon a master request.
There may be up to 10 slave units, all located in different locations around a site, all
monitoring and controlling different aspects of the SCADA system.
To set the TReX as a slave set MENU->TELEMETRY->MODE to SCADA_SLAVE.
