"Energy Active Total" keine Werte
OpenHallo Zusammen
Ich habe das Template von Schneider verwendet um folgende Zähler auszulesen. Zähler Typ: REG-Energiezähler Schneider iEM3155 3P+N 63A Modbus Mid
Ich bekommen alle vordefinierten Werte ausser die folgenden 4: Energy Active Total Import = 20272 Energy Active Total Export = 20270 Energy Reactive Total Import = 20276 Energy Reactive Total Export = 20274
Können sie mir da weiterhelfen?
Gruss Stephan

Hello Stephan,
If you want to read the sate you need to make an input on the modbus template and read the holding register of the same IO address as you are sending to.
The modbus template is made for a specific device, please keep in mind that when you are using this template with different devices that the modbus addresses may change depending on the product.
When looking in the added documentation the Energy Active Total Import is on IO address 3203 and not on 20272. This can be the problem you are having.
Also I see that the device is using 64 bit communication for the total Energy registers. As the iEM3155 is a RTU device it is not possible to read out this registers as 64 bit is only supported for TCP communication.
So it is not possible to read out the register for total Energy over RTU communication.
