RAKIB

Dear all,
I have to integrate almost 30 pac3200 (siemens), 10 PM1200 (schneider), 5 M2M(ABB) and 3 Conzerv DM 5240(schneider) digital meter in siemens system to monitor & represent electrical energy and power  consumption of different system. 
Please help me with your valuable suggestions how to integrate non siemens meters in siemens system. Please suggest briefly the networking of siemens system with non siemens meters. How to read write data from non siemens meters. Some meters are 300 meter, some 200 meter away from control room.
Thanks In advance.
 

 Hello Rakib;

One very valuable suggestion we can make is for you to do a bit of research on the communication possibilities for each of these  powermeter families.

For example, rthe Sentron PAC3200 support Modbus TCP:

Both the PM1200 and the M2M support Modbus RTU (RS-485); I will let you look on the web for the appropriate documentation.

The Converz 5240 powermeters, on the other hand, need an add-on modue for Modbus RTU:

If all is correct, then you would need 2 networks: one Ethernet (for Modbus TCP) switch every 100m, and a RS 485 serial bus for Modbus RTU. Since some of the power meters only go to 19,2 kB they can easily carry the signals over 300m on a shielded twisted-pair line.

So then you have to think of the CPU you will use. A S7-1200 for example supports Modbus TCP on its integrated Ethernet portsd and has Modbus TCP functions available. You would need a serial communication module for RS 485 if you want to implement Modbus RTU. Search for this information on the foeum, using the seach box at the top right of this page.

To help you further we would need a schematic of your plant, with the distances of each slave.

Hope this helps,

Hello,

yes, check some MB TCP - RTU Gateway which can change your MB TCP comm system to RTU.

Hello RAKIB

Do you also need help in Siemens communication to the PAC3200?

Perhaps this could help:

Hi Rakib.

You have quite a challenging task ahead of you, creating the PLC-program for all the devices. I have this modbus library which I think may help you. If you are interested I can help guide you through?

Kind Regards,
