Profile Setup via Modbus
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 using the the PC
software (available from your supplier). 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 the position 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.
Instruction Sequence to create a profile at the next available position
1. Create a profile by writing the profile header data using the Command Code value CP
(0x43, 0x50). This starts the profile creation process by reserving a profile memory slot.
The profile number is returned by the instrument in the Edit Response Message.
Note: There is a global block on profile creation or editing via Modbus while a
profile is running. An attempt to do so returns the error code 0x15.
The only profile related commands allowed while a profile runs are the Profile
Control & Status Parameters in the previous section.
