Example of HART programming (HART command interface)

Example of HART programming (HART command interface)
For HART channel 0, the command 01 is to be sent in transparent message format to the HART
field device with address "98 CF 38 84 F0".
A positive edge at input 4.0 of a digital input module leads to the writing of the HART command.
The following assumptions are made:
● The module address of the AQ 4xI HART analog module is 512 (200
● The data record is stored in DB80: starting from address 0.0, length of 11 bytes.
● In this example, DB80 (request data record for channel 0) consists of 11 bytes.
