True universal input on big 10A power supply
The new PS5R-G24 boasts a massive 10 Amps at 24VDC and features a true universal input (85-264VAC or 105-370VDC) that allows the user to ship their equipment anywhere in the world
OPC is the process control version of OLE.
It is also compatible with DDE (dynamic data exchange), an earlier version of client server technology.
This means that by using the tools found with data acquisition software, industrial HMI or MicroSoft Excel/Access, links can be built into WindSRV that allows real input/output, analogue and PLC register values to be passed through.
So, users can show what a process is doing by changing values, graphics, barcharts etc as it happens, in real time.
The ability to control an application is available by allowing the toggling of I/O and writing values back to the PLC.
Different versions of WindSRV are available which provide direct connection to a single PLC or multiple PLCs up to a maximum of 32.
Users combine the data from a number of PLCs to show how a production line is performing.
