1 BT. 2.3 Q/E Process controller with PROFIBUS DP and Modbus Master/Slave / DIN - 96 x 96 mm gammadue series Q line Sophisticated multifunction process controller with high level communications By its three different kinds of serial communications: PROFIBUS DP Slave Modbus Master Modbus Slave, the gammadue Q line can interface, on different levels, with other devices, by exchanging informations, after processing them by mathematical package. The frequency input, added to the traditional inputs, two retransmission or control analogue outputs and four programs allow you to use it for the most diversified control strategies.

3 Fuzzy-Tuning Two methods of initial tuning are available: - Auto-Tuning one shot - Natural frequency one shot The Fuzzy-Tuning automatically selects one of the two methods which assure the best result for each condition. The Auto-Tuning method works best on the step response basis. When activated, if a deviation exists between the Setpoint and process variable larger than % of scale range, the controller modifies the output value. Then, in a short time, it calculates the PID parameters and the new algorithm is operational immediately. The main advantages of this method are fast calculation and quick implementation. Setpoint change PV variable SP End of the tuning operating and setting of the new calculated terms. Start of autotune operation Tuning Two methods of tuning are available: - one shot initial Fuzzy-Tuning - self-teaching continuous Adaptive-Tuning Adaptive-Tuning It is self-teaching and waits for process change to recalculate the new PID parameters. The new PID calculation does not influence the control output, avoiding any disturbance. The PID optimisation is done only when necessary (e.g. Setpoint changes or process disturbances like load changes). No action by the operator is required. The operating mode of Adaptive-Tuning is safe and user friendly. It tests the process response after a disturbance, it memorises the intensity and frequency of the reaction, then the Adaptive- Tuning checks the new information with its statistical data base. The correct PID algorithm is then ready to implement. This tuning is ideal for nonlinear processes where the PID parameters must be adapted to changing conditions. Configuration software A software tool is available to improve both the configuration and the parameterization. All the data can be stored to file. It is also possible to down-load the linearisation of the custom input by using the polynomial s coefficients and to configure the PROFIBUS DP profile file. Integrity in data copy Memory chip The memory chip makes possible a fast and safe transfer of data related to the configuration and all parameters. With a simple operation, the information can be stored and copied to the memory chip. The procedure can be protected by a password. memory chip The Natural frequency method works best when the process variable is very near to the Setpoint. When activated, it causes a process oscillation around the Setpoint value. The main advantage of this method is a reduced disturbance to the process. Tuning start PV variable End of the tuning operating and setting of the new calculated terms. Disturbance New terms Up to profiles with 6 segments can be programmed. Number of cycles as well as the max. allowed deviation can be configured. The time base can be selected from seconds, minutes and hours.

4 The Fast view is a password protected review procedure of the most useful parameters. The combination of a luminous and comprehensive display and the ergonomic keypad allows the immediate access to the Fast view. Fast view Industrial standard for peripheral devices connection to a machine in a plant. The protocol installed in this controller, offers the following advantages against the standard normally supplied by other suppliers: Communications baudrate Up to 2 Mb/s with electric isolation PROFIBUS DP Slave The list of data transfer (profile file) is user configurable. It can be set by means the gammadue configuration software. Modbus serial communications allows a controller to exchange informations with other devices, gammadue series or others with Modbus Slave serial communications (PLC). For instance it is possible to read the acquired value from a gammadue C indicator with alarms and send this value as remote Setpoint to a gammadue X3 controller; or the gammadue Q controller can send the Setpoint profile of the running program to many X or Q controllers without Setpoint programmer function. An Q controller can realize a Modbus Master simple network for the low level data management. The Q can also reduce the work of the SCADA and grant the exchange of data in case of its failure. The mathematical package is able to process any information Mathematical package there is in the controller by using a simple set of mathematical operations. For instance it can compare two values by selecting higher or lower, to do the sum or the ratio and so on. Together with Modbus Master, it becomes a very powerful information handler; it can, for example, send to different controllers the same Setpoint profile with different values for every controller. AutoLink Self-configuring supervision software. Major features include monitoring and control of the connected devices, the visualisation by means of instrument faceplates, trend and mimic pages, data archiving as well as report generation. A self-configuring tool automatically polls the connected devices and build up the application software, reducing the start-up costs. 3
