Ethernet & Sequencer Programming SM15K4 / 44 DELTA ELEKTRONIKA B.V. rev. Aug. 20191 In General1.1 FeaturesThe Remote Ethernet programming function is an interface between a TCP/IP network and the PowerSupply. It allows the operator to create fully automated systems. The Ethernet interface can set andmeasure the parameters of the power supply, read the status signals, set controls, interacts with digital I/Oand generate waveforms, stored in memory. It is even possible to take over tasks from a PLC. That makesprocesses and test systems more powerful and less complex.1.2 AnalogThe power supplies of Delta Elektronika are very stable and accurate. The Ethernet interface is designedespecially for these kinds of power supplies. Therefore the programming and measuring resolution is 16bits and all units are calibrated very precisely by the factory. To calculate the step size in (Voltage orAmpere) use the equation below:To calculate the stepsize in Watt use the equation below:1.3 StatusThe power supplies are equipped with a lot of signals which inform the user about the status of the supply.Status like Limit, OverTemperature, DCF, etc. can be read to check the condition of the system.For example, ACF-signal (which indicates an incorrect input voltage) can be monitored, so action can betaken to avoid problems before a system is switched off.1.4 LEDsNext to the RJ45 connector are two LEDs, see picture below.The left orange LED is named "ERR". When this LED is ON, the Ethernet interface has generated an errormessage as a result of a bad command or parameter.The right Green LED is named "LNK/ACT", which stands for Link/Activity. This LED indicates whether ornot the Ethernet interface is connected and communicates.
