Schneider Electric promotes the Magelis SCU, which provides CANopen connectivity, especially for machines with limited complexity. The device integrates PLC functions and features a 3,5-inch or 5,7-inch TFT display.
ACCORDING TO THE FRENCH SUPPLIER, the combined PLC and HMI can save up to 30 % of the installation costs. Besides the CANopen interface, there are Ethernet, USB, and serial communication ports (EIA 232/485). The integrated PLC features PTO/PWM functionality and controls also the local I/O. There are six 24-VDC digital inputs, six digital relay outputs, two 13-bit analog inputs, two 16-bit analog outputs, two 16-bit temperature inputs as well as two pulse train source transistor outputs (50 kHz). The compact unit is suitable even for machines with limited space.
|Typical application with CANopen-connected drives and motion controllers|
The product is suitable for simple packaging and machine tool applications. The CANopen implementation provides NMT master functionality and is able to control one axis with 100-kHz counters and a 50-kHz PTO/PWM output. In process control applications the device can be used for pumps and HVAC. It provides analog I/O with tension/current signals and temperature inputs (e.g. PT100 and PT1000 probes). There are also pre-programmed function blocks for PID loops.
