SCADA - PLANT AUTOMATION SOLUTIONS

SCADA (Supervisory Control and Data Acquisition)+ HMI (Human Machine Interface)

= CCC (Control, Cost reduction and Confidence)

Remco Engineering's CCC systems use real-time data acquisition and trending to allow you to see what is happening with your business, as it happens. Any process can be automated and monitored by these systems. Pioneered in the chemical and petrochemical industries, new hardware and software now allow these systems to be used for everyday processes. This results in cost savings that pay for a system in a few months.

A quick example is the automation of a dosing system using day tanks and large holding tanks used to fill the day tanks.

• The system has 3 tanks, waste acid, waste base, and batch.
• The batch tank is recirculated if there is waste to treat.
• The chrome/base waste is added to a certain level (ultrasonic level).
• Acid from the batch acid tank is added to reduce the pH to 2.5. If the acid tank is empty, a metering pump is activated.
• Once the pH is correct, the ORP is adjusted with a reducing agent. ORP is monitored
• The system waits for 1/2 hr for the chrome to be reduced
• The pH is raised to 8 with a metering pump
• The waste is transferred to a cone tank for flocculation. 

This is all automatic plus there are many if/then logic steps and wait timers built in to tell the system what to do if a tank is empty or the transfer tank is full. The operators in this case just keep the dosing tanks full. We can actually monitor the chemical usage by accumulating the time the metering pumps are on.

Both analog and digital types of signals can be monitored and controlled.

You can:

• Turn pumps, valve, switches on and off,
• Measure and log pH, conductivity, viscosity, pressure, temperature, flow rate and volume, parts, weight, color, etc.,
• Alarm and notify by phone, e-mail, buzzer, etc.
• Log any data and create real-time trending charts.

Displays are color coded and indicate real-time conditions. An individual object can have many different colors coded to indicate various states. Tank levels can change color to indicate low, high, and operating conditions.

If you have existing PLC's now, you can plug them into a SCADA system with the appropriate driver and then monitor and control that system in real time. You can measure chemical usage, parts counts, or any other parameter. Multiple PLC types can be monitored with one system.

The real advantages of a SCADA system is that you have a real-time control of inventories and can program a system to "see ahead", to notify you that the tank will be empty in "76 hrs". It also will take most operator errors (or neglect) out of the process. The system doesn't tire, take breaks, or go on vacation. You can monitor the system over a network, from a remote site over the Internet or through a dial-up line. It can decide who to notify and if the situation is not corrected, be programmed to alert personal at higher levels of responsibility.

Systems have multiple levels of security available so that screens can be locked, hidden or display only depending on the security level. Higher levels of authorization can change setpoints and timing.

Updating software is a dial-up operation and is easily done without a site visit. Once a system is running, program changes are easily made at little cost. We can remotely monitor a system to debug or update software in real time. The system stays running while we work. 

The potential is endless, only limited by your imagination. Costs are relative low and the new object oriented systems can be programmed rapidly. You can have a 50 point system running is a few weeks, a 500 point system in a few months.
