Note
• Information for skipped measurement channels, computation channels when
computation is turned OFF, and control channels when control is turned OFF is not
output.
• Alarm setting values for control channels set by loops are output as alarm information
for the PV, SP, and OUT channels corresponding to the alarm types.
• When alarms are OFF, 0 is output for the alarm setting.
• If the alarm type is 0 in the control groups (control alarm OFF), an alarm value of 0 is
output as alarm information for the PV channels.
• Information for channels belonging to loops set for analog retransmission are not
output.
Output of Upper/Lower Limit of Input Span and Decimal Point Position for
Measurement/Computation/Control Channels (Style number S3 or later)
• Upper/lower limit of input span and decimal place for measurement/computation/
control channels are output using the FT command.
• The output format identifier is 1. See page 7-3, “Identifier.”
