Series SD Profiling Modbus Registers
This section contains information for creating, editing and running profiles using Modbus. Some of these are available
only through Modbus and others can be accessed through the front panel and Modbus. If a parameter is accessible
only through Modbus, N/A appears in the display column. Parameters appear in profiling version only.
