PLC
The PowerFlex 6000 uses a Micro850 PLC to perform many of its internal 
control functions. The PLC controls and monitors the cooling fans, input and 
bypass switching devices, door switch status, etc. The PLC is also responsible for 
interfacing with the user's automation control system via many optional 
communication protocols. Standard communication protocols are EtherNet/IP, 
Modbus/TCP Server and Modbus RTU. Optional communication modules are 
available to support other communication protocols.

HMI
The PowerFlex 6000 HMI is a PanelView™ Plus 6 series, catalog number 2711P-
T7C4D9.
The HMI is connected to the controller (Micro850) through a communication 
interface (standard RJ45 EtherNet/IP connection). The HMI configures 
operating parameters and input operation commands, and displays the operation 
status, operation parameters, parameter trends, and fault messages.
