54 1794-IF8IH and 1794-OF8IH Configuration
Data Table Reference: CMD3 Comm Status, Secondary Input Word 0
bits 0…7.
HART Field Device Command and Communication Status (8 of 8
bits)
This byte indicates the status of HART FD communication for the channel. It
is the first status byte of the HART response and the FD status, example:
"parity error", "framing error", "invalid selection" or "too few data bytes
received" is coded in.
Data Table Reference: HART Comm Status, Secondary Input Word a,
bits 0…7.
HART Field Device Status (8 of 8 bits)
This byte is part of the CMD 3 data response of the HART FD. It is the
second status byte of the HART response and the FD status, example:
"primary variable out of limits" or "analog output saturated" is coded in.
Data Table Reference: HART Field Device Status, Secondary Input Word a,
bits 8…15.
