Why does F-AI become passive when HART communication is enabled?

Why does F-AI become passive when HART communication is enabled?

Answers

Top answer

~ Trying F-AI to communicate with the HART protocol causes a heavy load on the network. Take the following steps to avoid this:

  • Parameterize the "HART gateway" as a variable. (Hart can only be switched on and off when modules are in RUN mode. Only turn on HART when needed.)
  • Turn off HART communication for channels that do not use it. (spare or channels connected to sensors)

It is important to note that when HART is off, diagnostic data cannot be sent to PCS 7 Aram Management.
