Hello Slab; Is your problem reading the Harmonic Voltages or reading these over Profinet? The following manual, in Appendix A3, shows that Harmonic Voltages up to the 31rd (odd harmonics) can be transfered over Modbus (RTU or TCP), starting at offset 9001. SENTRON PAC4200 Power Monitoring Device System Manual Siemens now proposes an optional Switched Ethenet interface for the PAC 4200 and 3200 that allows it to communicate over Profinet: There are two solutions possible (to transfer measured values over Ethernet, the second one being Open Modbus TCP) 1. By using the Switched Ethernet PROFINET Module 7KM9300-0AE00-0AA0 with PROFINET IO and PROFIenergy... See here: Ethernet communication SENTRON PAC3200 and PAC4200 to Simatic S7 PROFIenergy - Saving Energy with SIMATIC S7 Hope this helps, Daniel Chartier |

Hello slab; Although the harmonic voltages and currents are available in the Sentron PAC 4200 GSDML file, (available here: GSDML-File: Switched Ethernet PROFINET Module) which means they can be requested by cyclic comms over profinet (as you already stated), it seems that you cannot access them through acyclic communications, even using ProfiEnergy. See the application note attached.It contains a list of all measurements available acyclically, and Harmonic values are not shown. Hope this helps, Daniel Chartier Attachment41986454_PROFIenergy_SENTRON_DOKU_V10_en[1].pdf (201 Downloads) |
