2.9. Uploading and Downloading of Profiles
The information in this section is intended for advanced users writing their own software code.
Most users will create or edit profiles using the instrument keypad or via BlueControl. Either
method allows quick and easy editing of profiles.
Advanced users can setup or edit profiles by writing to the Profile Configuration parameter at
address 8198 (0x2006). This can only be accessed by using Modbus function code 23 (0x17). The
instrument replies with a status message.
When creating a new profile the steps below must be followed exactly, either to create a profile at
the next available position, or at a position that you specify.
Each message in the sequence includes a 2 byte Command Code that tells the instrument the
purpose of the message, and therefore the meaning of the data contained in it.
The command codes support by this instrument are:
