Title: Suggest an HMI Controller Post by: itp on December 08, 2015, 12:02:32 12:02 I am in search of an HMI controller module ( HMI controller means a Human Machine Interface with Builtin PLC)
for controlling a power supply. My requirements are as follows. HMI size: 5.7" Colour Digital input : 8 Nos Digital Output : 8 Nos Analog input: 4Channels, 12bit (Voltage input) Analog Output: 2Channels 12bit (Voltage Output) Comm ports: Ethernet, RS232 Built-in Web-server for remote HMI access. Software for above controller configuration and user interface design. Please suggest a product with minimum cost. Thanks and regards Itp Title: Re: Suggest an HMI Controller Post by: zawmintun1 on December 09, 2015, 05:30:25 05:30 Delta Scada HMI

Automation Direct makes some modest cost PLC/HMI combos Siemens S7-1200 units can be surprisingly cost competitive as well if they are hungry for market share in your area. The processing power of the PLC and quality of design software will also play a role in how much this costs. Title: Re: Suggest an HMI Controller Post by: itp on January 05, 2016, 04:54:13 16:54 Hi,
I need a 16-bit Analog output module with a stability of 20ppm/deg.C or better for this project. I could not found any yet. Can anybody suggest one. Next option in front of me is to design a micro controller based card with a highly stable 16-bit DAC (Like LTC2602). But how to interface this card with an HMI. Any Idea. Regards Itp |
