The ADN 412 has been developed as a dual CNC control unit for operation with two correcting elements in which the electronics are mounted on the valves. The assembly consists of two modules, of types MD6 and MD15.
MD6 is the basic module (equivalent to ADN 407). The MD15 is the add-on CNC module. The MD15 CNC module is also used in other device combinations, due to the modular structure of this system. The ADN 407 basic module has, in the present case, already been described, with the result that this outline description relates primarily to the add-on module.
The MD15 CNC module is equipped with two SSI interfaces for operation with absolute position encoders, such as absolute shaft encoders or Temposonic, for example.
The position encoder is supplied with power from the ADN 412.
The MD15 CNC module is equipped with its own 16bit signal processor, which has a processing speed of 40MIPS. A further four inputs and four outputs are also provided, with the result that the ADN 412 device combination has a total of 11 inputs and 5 outputs.
A Profibus DP can be used as an option. We then supply the Profibus GSD file, which contains all important information for data input, status displays and diagnosis.
The ADN 412 device has been created by combining the MD6 (ADN 407) and the MD15. It has a width of 45mm and is suitable for installation on DIN 50022 rails.
The ADN 412 is equipped with two microprocessors, each of 40MIPS. Combination of digital and analog sensors is therefore possible in special cases without overloading the microprocessors' processing speed.
The ADN 412 is equipped with the CAN bus, which permits communication of a large number of devices with one another. The augmentation of such a device group with Profibus assures an interface to the majority of PLC control systems.
As already mentioned in the outline description of the ADN 407, the MD6 basic module does not feature an output stage for valves on which the output stage is mounted on the valve itself.
All settings for the ADN 412 are effected using the ADN configurator via an RS232 interface linked to a PC or laptop computer.
The input software ADN configurator is available on the Internet.
