C.9: Internal Indication Bits
Bits implemented in the Shark® 200 meter are listed below. All others are always
reported as zeros.
Bad Function
Occurs if the function code in a User Data request is not Read (0x01), Write (0x02),
Direct Operate (0x05), or Direct Operate, No Ack (0x06).
Object Unknown
Occurs if an unsupported object is specified for the Read function. Only objects 10,
20, 30, and 60 are supported.
Out of Range
Occurs for most other errors in a request, such as requesting points that don’t exist or
direct operate requests in unsupported formats.
Buffer Overflow
Occurs if a read request or a read response is too large for its respective buffer. In
general, if the request overflows, there will be no data in the response while if the
response overflows at least the first object will be returned. The largest acceptable
request has a length field of 26, i.e. link header plus 21 bytes more, not counting
checksums. The largest possible response has 7 blocks plus the link header.

All Stations
These 2 bits are reported in accordance with standard practice.
