Using Siemens was an easy choice due to its known reliability, off the
shelf availability and competitive cost. To add to this, it’s ease of
implement, program and to fault-find due to the TIA Portal software. We
find that if and when there is an issue on site, we are able to remotely
diagnose the system via the WAN Ethernet telemetry radio network with ease.
The flexibility of the S7-1200 to have DNP3 and other multiple protocols
built in such as Modbus TCP allowed easy integration into the councils third
party SCADA and PLCs. This was supplemented by the easy integration
into existing infrastructure with the communication via Modbus TCP. Efficient
engineering with TIA Portal allowed the systems integrator, R&D Technology
to engineer both the control and monitoring aspect with one software package
not requiring multiples to complete the project. This reduces the chance of
errors and saves time in engineering
