The TPC 4000 is at the heart of the control system and can be set up to control any machine in a way that the operator requires it to be controlled including machine master / slave linking. Most manufacturers state the way in which the machine shall be controlled in terms of valve sequences, to satisfy an operators required function. In the TPC 4000, it is the operator in conjunction with the commissioning engineer that determine how the machine shall operate. This is a unique and flexible approach to Dyemachine control and gives control to the user via software configuration.
There is an LCD display window on the Controller which shows many lines of information about the state of the Controller. The display will show such information as Profile Name, Current Operation, Current Temperature, Target Temperature, Time To Go, Operator Messages etc.
The Controller can be programmed to follow a prescribed process profile. This profile can be selected directly at the keypad, or entered and selected remotely from the Supervisor system PC. Similarly, the Controller can be Stopped, Started and Acknowledged either directly, or remotely.
The Controller system consists of an HMI (Human Machine Interface) unit which is located in the door of an industrial panel, and a number of I/O Modules that drive the output valves and reads the input sensor values. Typical valves might be:- Heating, Cooling, Heatexchanger Drain, Fill, Drain, Transfer, Addition, Isolate etc.
Typical inputs might be:- Level Floats, Safety Switches, Temperature Probes, Operator Interface Controls, Pressure Sensors, pH Controllers, etc.
The commissioning engineer will write many different flexiware software routines, called macros, which are groups of machine valve operating instructions. These macros are then executed, as and when required, to undertake the Dyers request for the machine to perform specific functions such as FILL, RAMP, HOLD, DRAIN, TRANSFER etc. as written in his profile. Each Dyers profile command has an associated sequence of macros to perform the programmed task. As these macros are written and maintained by the user, reference back to the manufacturer for changes to the way the machine is controlled, is therefore NOT required.
