The Industrial PLC Unit employs the widely used Allen Bradley SLC500, together with suitable software and hardware connections to allow a multi-channel compatibility with selected instructional equipment from the Armfield range. The Unit accepts up to 6 analogue and 8 digital input signals and provides 2 analogue and 8 digital output signals for use in configuring a wide variety of control loops for study and demonstration. Ladder logic software is provided on disk to permit the unit to operate as: Programming the Unit requires a PC (not supplied) with RS232 serial communications to allow: ii) Monitoring: Users may modify or re-write the ladder logic from a PC. Two built-in manually adjustable voltage sources are provided on the front panel to use as inputs to learn and demonstrate ladder logic, with a built-in LCD voltmeter to monitor outputs. A 9-pin serial cable is provided (for connection to a PC), as is a 6-pin DIN connector to obtain power from Armfield process hardware. (see text under 'Essential Additional Equipment'). |
The unit consists of a Honeywell UDC3300 PID controller mounted in a standard console along with connectors for inputs and outputs to selected instructional equipment from the Armfield range. In addition to the analogue input/output, relay and alarm sockets are provided for a digital output control action. An RS232 port allows serial communications with a user-provided PC. ncorporates widely used Honeywell UDC3300 industrial PID controller. > PID with alarm and relay outputs > configuration in engineering units > serial communications RS232 and RS485 > introduction to SCADA, (supervision of the controller by a PC) using Windows based serial communication software > temperature/time profile set-point ramp facility > fuzzy and adaptive tuning > alternative control algorithm > dual set-points |

The process plant trainer can be used to demonstrate a complete range of process control methods and strategies. Manual control, single feedback loops, through to sophisticated cascade loops and distributed supervisory control of the whole process by a remotely located computer can be demonstrated. The system is a miniature replication of a true production process. The student is presented with real process control problems, with realistic dynamic behavior and instabilities in an easy to use process control trainer. Multiple inputs, multiple sensors, multiple control strategies > Temperature, level, flow and conductivity control loops can be implemented > Effects of 'dead time' > Operational sequencing, including start up to shut down > Recycle implications on process control > on/off, proportioning, PID, PLC, SCADA > fault simulation and diagnosis > includes computer interface (USB) and sophisticated educational and data logging software The control console provides the electrical interface and signal conditioning for the process module. It also includes a USB interface for a Windows computer. The process module sensor outputs can be displayed in engineering units on an integral LED display. The outputs are also available for external monitoring. The drive signals to the process module can be selected as either manual control from the front panel, control from a PC via the USB bus, on/off control from an external source (e.g. the armfield PCT19BR PLC), or analogue control from an external source (e.g. the armfield The source signals for both pumps and the heater are individually selectable. |
The system provides a cost-effective way of teaching a wide range of process control techniques in a simple basic unit. More advanced aspects of process control can be addressed by adding optional extras to the basic system. The basic is used under computer control to demonstrate a variety of single control loops. It can be quickly reconfigured between processes, such as level control, temperature control, flow control and pressure control. The advanced software allows the student to change the control parameters, record results and analyse the results for the different configurations > The expands on the capabilities of the, and offers a wider range of control loops and strategies, including remote set points, dual loops, fluid property control (using conductivity). Again all these are under software control > Other Accessories are available, including a control console with commercial PID controller, plus a pH probe and a pneumatic valve for those wishing to implement specialised demonstrations > Large range of demonstrations from straightforward hardware > Computer control as standard > Computer generated loop disturbances for repeatability, allowing small variations in control parameters to be investigated > Flexible system, suitable for project work |
