We are looking to develop a data acquision system using Verizon wireless telemetry service to monitor operation of the device being monitored.
The system will alert a central office if there is a problem with the device,we want to monitor 12 discrete inputs, if all the inputs are ok, go ahead and operate the device.
If the device fails to operate notify the central office by sending an error code, the error code must include the device number, what failed, date and time stamps.
We also want the ability to operate the device remotely on rare occations.
I can't give too much more detail w/o a NDA. I have some limited PLC programming knowledge of escalators and elevators, so I do have the basic concept and how it should work mapped out.
I also need assistance to spec out a PLC which will integrate with Verizon Wireless telemetry service.
