PM 500 Merlin Gerin to WinCC Modbus


Thread Starter


I try to conect several PM500 to WinCC v5.1 via Modbus Serial but the Wincc system always read 0 in all the registers.

Can you help me?
Thank you.
Then why don't you try for another similar product like Rishintegra 1540 which is at better price & better technology.

Best Regards,
