Dear all,
I have PLC that connect to PC via UNITELWAY (I use TSX MICRO 37-22 from Modicon-Telemecanique).
I installed Wonderware Intouch as HMI Software.
Now, I want to develop such a feature that I can controlling and monitoring my plant that connected to PLC via mobile phone, such as SMS or WAP application. What I want to ask :
which one of this, SMS or WAP that I can use.
I am really appriciate to discuss with you all ..
Thanks.

 

You can do it with SMS.

What you would need is a GSM Modem (it has a SIM card) connected to your Wonderware Machine on the serial port.

When anyone sends an SMS to this Modem , you can read it into the PC and take the necessay steps based on the Command.

You can also send data vis SMS through the Modem to any other phone.

You can write an OPC compliant VB-based application which will act as a bridge between Wonderware and the GSM Modem.
