Controlling a water tower and pump


Thread Starter

Heath Lovell

We are wanting to monitor the water pressure on the city's water tower. We would like to dial in to a computer using PCAnywhere. I don't know what hardware I need to install in the computer or what software to use. Basically, we need to monitor a couple of 4-20mA sensors. I would like to have some options for controling pumps (a couple of dry contacts) down the road once everything works.
I would also be interested in a solutions using AB PLC's (maybe the micrologix) but I didn't know the dial-in capabilities of that unit.
Any help is greatly appreciated.

Been there done that using Opto22 hardware at the water tower and in the treatment plant. Configure the hardware with 4-20 in or out modules, digital
in or out, AC or DC. Program to turn pumps on/off, send levels, alarms. Dial-up modems, leased-line, radios, it makes no difference to the Opto hardware because of the serial port options. PC-Anywhere will run on any computer just install it, Win95,98,NT.

Miille Applied Research has slot mounted dial up modems for the Allen-Bradley SLC 500 PLC. They can auto answer as well as dial out depending on your requirements.

You need a pressure transmitter, a small control panel, a controller, communication equipment, a host computer, wiring diagrams, O&M manuals, HMI software, programming software, etc. It's a small project and there are literally thousands
of way to do it, but you DO need to engineer this. I suggest you avail yourself of the services of a systems integration firm in your area. Ask your AB rep for a reference.

You can check B&B electronics, they carry SIXNET industrial modem for dial in communication. Pwer required: 10-30VDC.
We want the same thing to moniter the supply of water in all deirection of city and to moniter the storage in tank. this is what exactly we want
but I dont know the hardware part of it which require as the interface part of it i can do as i am programmer in VC.
the only thing i want to clear is the exact hardware requirement and its type.
Any help is greatly appreciated.
