The a1-cbiss team are often asked by their customers to supply two emissions analysers acting as a redundant pair to ensure maximum monitoring uptime. These two analysers are used for acquiring the data, displaying and reporting data.
a1-cbiss approached Amplicon to design a cost effective and easy to install solution that would also take account of the criticality of the application. The hardware requirement included the following instrumentation: HMI screen for operator input (touch screen), relay outputs, programmable logic control and a TCP communications interface.
At the time a1-cbiss contacted Amplicon they were using a system based on a PC with distributed I/O modules. It was quickly ascertained that the application did not require the processing power of a PC and as there was a limited footprint, this was an area where improvements could be made by selecting more suitable hardware. The application did however require an HMI screen, so using a PLC solution would have proved unsuitable.
The Amplicon team realised that this application would require a device that had the features of an industrial computer to drive the HMI screen plus the I/O and control capabilities of a PLC.
Having understood the customer requirements Amplicon recommended the ViewPAC product line of programmable automation controllers. The ViewPAC is a programmable automation controller offering HMI, data acquisition and control functions in one unit.
Amplicon specified the ViewPAC series as it has a choice of difference operating systems (WinCE 5.0, Linux and MiniOS7), as well as different sized touch screen displays (3.5”, 5.7” and 10.4”). For this particular application, the WinCE model with a 10.4” was selected.
