The Ascon’s deltadue offers a complete series of
· analogue and digital I/O modules,
· single and dual loop PID control modules
· acquisition and transmitter modules
· gateways, repeaters, line adapters and line converters
· WebSCADAs
· Manager modules
Applications include the use of the modules as independent units or as field interfaces of PC based systems or as integration/expansion of PLCs
Connectivity is the strong point of the ‘deltadue’ series of control and acquisition modules.
A wide range of control system architectures can be realized by connecting the modules to:
· a PLC or SCADA with MODBUS TCP via an Ethernet network or the web
· any web browser for the configuration of HTML management pages and to MODBUS TCP SCADAs via an Ethernet network
· a MODBUS TCP SCADA and to a PLC simultaneously (respectively via an Ethernet network and PROFIBUS DP/MODBUS RTU/DeviceNet)
· CANopen, PROFIBUS DP, DeviceNet networks
· MODBUS RTU networks with different baud rate, parity and stop bits
· two masters, such as Operator Panels, SCADA, PACs, simultaneously
An optional Manager module provides:
· automatic learning and back-up of the configuration data of the modules
· hot swapping. To maximize process uptime
· automatic configuration of replaced modules. To reduce machine downtime. While one failed module is replaced, the other modules work normally
· offline configuration to simplify start-up. When the modules are inserted, they are recognised, configured and parameters are downloaded
· diagnostics. The scanning of the connected modules allows to verify if they are the correct ones and if they work properly. Actions can be taken quickly
Features include:
universal analogue inputs (Pt100, T/C, mA, mV);
current transformer input; digital inputs/outputs;
PID algorithm with overshoot control; heat/cool PID;
Auto tuning; Set point management;
universal control outputs (mA, relay, SSR);
timer, PWM. toggle and flip-flop functions;
embedded RS485 Modbus RTU serial communications
Modules work as independent units; no backplanes or common modules are necessary
The Manager module and the Gateways are only needed when their functions are necessary
Ascon also offers a wide range of operator panels
