Module Configuration Overview
Like other Field Control modules, the RTD Input module is usually configured from the Bus
Interface Unit, using a compatible hand-held programmer. The module will also accept
configuration data from the bus when used in a system that supports such configuration.
The table below summarizes configuration choices and defaults. The module will power up
with the default configuration settings. For configuration instructions, refer to the Bus
Interface Unit User's Manual.
Module
Parameter
Analog Input
Word length of the module's analog input
Data Length
data in the BIU's analog input (AI) data table.
Analog Input
Starting offset for the module's analog input
Data Reference
data in the BIU's analog input (AI) table.
Discrete Input
Bit length for the module's optional status
Data Length
data in the BIU's discrete input (I) table.
Discrete Input
Starting offset for the module's status data
Data Reference

output (Q) table.
Discete Output
Starting offset for the module's optional
Data Reference
fault-clearing bits in the BIU's discete
output table.
Analog Output
Word length for analog output data in the
Data Length
BIU's analog output (AQ) table. Should not
be used for most applications.
Analog Output
Starting offset for the module's analog
Data Reference
output data in the BIU's AQ table.
Line Frequency
Specifies the line frequency.
Channel Active
Specifies if the channel should return data
and alarms. If a channel is "inactive" space
is still allocated for it.
Units
The conversion type for each RTD.
RTD Type
The type of RTD used for each channel.
Wire Type
The type of field wiring for each RTD.
Alarm Low
The low alarm limit for the channel, in
engineering units.
Alarm High
The high alarm limit for the channel, in
engineering units.
Resistance
An optional resistance adjustment, in tenths
of ohms.
