HART Multiplexer Master KFD2-HMM-16
For the given loop the actual special parameters and, if
available, the transmitter data are returned. These are:
• Loop number
• Error flag (0=OK, 1=special SCAN not activated)
• Polling address (always 0, no multidrop)
• Threshold data length for special SCAN
• Selected SCAN command
• Long frame address
• Number of available data bytes
• The data bytes itself (if any)
For the given current loop and polling address (has to
be 0) the threshold data length (0 ... 62) and the SCAN
command to be used can be written.
When the multiplexer switches the communication
channel (loop 0 ... 255) it can insert a delay time
(0 ms ... 300 ms) before any HART commands are sent
to the loop. This is necessary when using the multiple-
xer together with the RPI product family of
Pepperl+Fuchs.
