AI895 Section 3 Run-time Operation
88 3BSE027630-600 B
• Hardware faults
Shows one of the following faults for the module:
– Channel fault (of any HART channels)
–ROM fault
– EEPROM fault
• Instruments communication error
Shows the summary of the communication error bits for the instruments.
According to the HART protocol specification.
• Instruments status
Shows the summary of the status bits for the instruments. According to the
HART protocol specification.
Channel status area
• Channel 1 - 8
Shows the instruments scan faults and status. Following status can be shown,
Scan enabled, Searching, Disappeared, Appeared, Mismatched. See
Scan
enabled for more information on different status.
An empty box means that no instrument was found and have not been present
on this channel before.
General status area
The status can be of three different types, either it is a communication error,
command response or field device status. Note that if it is a communication error,
the other statuses will then be empty. These status bytes are defined by the HART
protocol specification. See appropriate HART documentation for more detailed
information.
Communication errors are mostly those which will be detected by a UART, like
parity, overrun and framing errors. The field device reports RX (receive buffer for
HART messages) overflow and check sum error.
Command response codes are categorized as either errors or warnings, which could
have a single meaning or multiple meaning. The codes listed below are those which
could be applicable to all transactions. There could also be private defined meanings
for some numbers.
