System Mimicing?
System Mimicing?
(OP)
Hi,
We have a system utilizing a Standard Mitsubishi Q series PLC on a site in Belfast, utilizing a HMI for control of the system by the operator.
The system is basically two 25000L tanks of chilled milk that is kept in constant circulation around a ring main and then tapped off as demanded by a mixer in the bakery.
The HMI displayes information such as tank levels and tank temps amongst many other things that would be very useful to monitor from a remote location at any time.
Is there anything out there similar to say 'teamviewer' for Windows that would allow me to view what is being displayed on the HMI at any given time from any location via a GSM network?
The tank levels are determined by Vishay load cells (mA output) and PT100 temp probes (Klay / Vega or similar)
Many thanks

I think the HMI is a Siemens HMI.
RE: System Mimicing?
It's one way of duplicating HMI displays.
Does this particular HMI include a web server?
RE: System Mimicing?
Siemens offers two class of HMI: WinCC which runs on standard PC hardware, and the Simatic OP?TP panels.
How does the current HMI communicate to the PLC? Serial cable, Ethernet etc?
RE: System Mimicing?
Secondly an answer to your questions. The HMI is connected directly to the PLC I.e. It isn't PC controlled. It is connected to the Mitsubishi Q series via an ethernet cable, with a seperate power supply providing 24vdc for the screen.
The PLC has a GSM modem connected. I don't think the HMI has an internal server.
Thanks
RE: System Mimicing?
I suggest that you get in touch with a local systems integrator for help.
