Hye All,

I need to measure 10 active power on a special machine (5 one phase (monophase) or 5 three phase (triphase))

This machine have a S7-1214 DC/DC/DC CPU.

The existing Electrical cabinet (with S7-1200) is full, so I will make a remote electrical box.

I need that measures (active power) back to the S7-1200 for processing.

What product could make this type of measurement ?

It's possible to work on profinet bus or modbus TCP ?

Regards,

Cortex.

Hello cortexm

I know the Sentron PAC Devices from Siemens to mesure everything which depends on Power,and so on.

Look at this for example:

I already use a SENTRON PAC 3200,who communicate with S7-1200.

But I need to measure 10 active power.

What do you think about energy meter SM 1238 ?

• The Energy Meter module SM1238, which precisely records energy flows. The new SM1238 Energy Meter module for Simatic S7-1200 Basic Controllers can be used to record energy flows simply and precisely, directly on the machine. The measurements are processed directly in the CPU, and visualised with an HMI (Human Machine Interface) system, such as a Basic or Comfort Panel.
