Could a 1200 baud rate (equivalent to a signal change every 0.833 milliseconds) cause issues with an RPI of 5 ms for HART communication?
The main consideration is whether the baud rate and RPI are compatible for reliable communication. The HART protocol typically operates at 1200 baud and is designed to handle the timing requirements of industrial communication.
In practice, a 1200 baud rate should not cause issues with an RPI of 5 ms for HART communication. The protocol is designed to operate effectively within these parameters. The critical factor is that HART messages are typically structured to ensure that data is transmitted and received reliably within the constraints of the baud rate and timing intervals.
Thus, under normal circumstances, a 1200 baud rate with a 5 ms RPI should not create any significant problems for HART communication.
