Modularity and Extensibility

Most systems are tailor made for a given environment and client. The SCADA-TEMS is no different. However, a major difference is the modularity of the design. Hardware-wise a central control module with a uniform interface enables system integrators to attach multiple sensing devices to a single control module. This allows the system to scale by being able to attach a large number of devices to a single SCADA-TEMS control module. This is because the SCADA-TEMS control module was designed to be able to multiplex the available parallel port lines in order to accommodate a large number of sensors and control units. In the SCADA-TEMS server, dynamically loadable system modules allow the systems integrators to write a SCADA-TEMS software module and dynamically load it into the system without having to recompile or restart the system. The system integrators do not need to know about the internals of the SCADA-TEMS server to be able to integrate their hardware. It is just a matter of writing the necessary methods for the SCADA-TEMS software module in the proper format.
