Modbus Register Maps for APC by Schneider Electric Rack PDU's

Issue:
Looking for Modbus Register Maps for APC by Schneider Electric Rack PDU's

Product:
APC by Schneider Electric Rack Mountable PDU's with part numbers beginning with AP88XX, AP89XX, AP78XXB, AP79XXB, APDU99XX, APDU11XXXX, EPDU1XXXX, EPDU2XXXX

Solution:

Most APC Rack PDUs support Modbus over TCP. However, units equipped with first-generation Network Management Cards (NMC1) do not include Modbus functionality.

Modbus support is available on:

Rack PDUs with NMC2 running firmware version 6.x.x or higher
All Rack PDUs based on NMC3 technology

Important Note: The APDU10XXXX Advanced Rack PDU series does not use NMC3 technology and therefore does not support Modbus. This series has been replaced by the APDU11XXXX variant, which incorporates NMC3 and provides full Modbus functionality.
