Channel Status Word Bits in Integer Mode
The Channel Status word has the following differences when used in integer
mode.
• Only the Output in Hold condition is reported by the module.
• Calibration Fault reporting is not available in this word, although the
Calibration Fault bit in the Module Fault word will still activate when
that condition exists on any channel.
• There is only one Channel Status word for all six channels.
The table lists the conditions that set each of the word bits.
Tag (Status
word) Bit Event that sets this tag
ChxInHold Even-numbered bits from
bit 14…bit 0 (that is, bit 14
represents channel 0).
For a full listing of the
channels these bits
represent, see
page 183 .
The Output In Hold bit is set when the output channel is currently holding. The
bit resets when the requested Run mode output value is within 0.1% of
full-scale of the current echo value.
IMPORTANT
The 1756-OF6CI and 1756-OF6VI modules do not use bits 15,
13, 11, 9, 7 or 5 in this mode.
