=AUTOMATJON CD VAR-IO Modular controller system Highly modular system with 4 to 30 loops: bus coupler, controller unit, any I/O modules. Required components are simply plugged together: the interconnections are made automatically. Open for all interfaces: Ethernet, Profibus DP, CANopen, DeviceNet, Modbus. Digital and analog I/O modules in different modularities: 2, 4, 6, 8 or 16 channels.

For this, it is possible to choose between simple on/off control, DPID control, motorized stepping or master/slave control for each channel. Due to the modular system concept, any combination of input & output signals can be implemented. By means of the integrated monitoring functions for heating current and input/control loops, every fault in the entire control loop can be diagnosed. Modular, up to 30 channels As standard, the CD Var-io is fitted with the necessary I/O for up to 8 control loops. Simply by plugging additional I/O modules into the system, a finely graduated expansion up to 30 control loops is possible. This means that no more I/O modules have to be installed than actually needed. The maximum configuration allows up to 60 analog outputs, up to 34 analog inputs and up to 320 digital inputs or outputs to be processed. Every system is connected to an arbitrary field bus coupler, which also provides the supply voltage for the entire system. Thus only one field bus coupler, one CD Var-io controller, and possibly some additional I/O modules are required per multi-controller system. Automatic inter-connections reduce installation time The necessary modules of a CD Var-io system are simply plugged together without the need for tools. All peripheral and data signals, as well as the supply voltages are connected automatically. The external 24 VDC system supply must only be connected to the bus coupler at one point. Thanks to the plug-in spring clamp connectors for the I/O wiring, quick and simple module replacement is ensured. Identifying labels provide convenient I/O marking. Engineering Tool "BlueControl" Configuration of the CD Var-io is done by means of the powerful and easy-to-use Engineering Tool "BlueControl", which is connected via a separate RS 232 interface on the CD Var-io.

BlueControl also allows convenient operation and monitoring of the control system, plus simulation functions for control mode and control loop. Fast software update via BlueFlasher Via the local RS 232 interface of the CD Var-io, loading a software update into the controller's Flash EPROM is a simple matter. Simple system configuration via BlueControl Apart from a field bus coupler and a CD Var-io controller, there is choice of some 20 different I/O modules for making up a CD Var-io multicontroller system. Hereby, the number of required control loops (max. 30) is just as freely...

Second setpoint and ramp function Via any of the digital inputs or the field bus, a second setpoint can be activated (e.g. for setpoint lowering). By means of the setpoint gradient (ramp) function, which starts automatically during system start-up and after every change of the setpoint value, the function ramps up or down to the new setpoint value. Ramped heat-up This 'automatic' temperature ramping function prevents thermal stresses within a group of heating zones. The CD Var-io automatically detects the zone with the slowest heating gradient, and controls the gradient of all the other...
