Overview of the Temperature Input Units
This section provides an overview of the Temperature Input Units, including
details on functions and setting methods.
6-1-1
Temperature Input Units
In addition to the functions common to the GRT1 Series (backup, restore,
online conversion, etc.), other functions specific to the Temperature Input
Units (scaling, peak/bottom hold, etc.) are available. The Temperature Input
Units are also able to internally perform math on temperature input values,
which previously required ladder programming in the host PLC. Temperature
data can be selected from the six values obtained from math operations and
allocated as I/O in combination with Status Flags or other status information.
The Setting Tool can be used to allocate this status data, to make settings for
monitoring and specific Temperature Input Unit functions, and to monitor
operation.

1/100 display mode
The temperature data is multiplied by 100 and sent to the Master as 8-digit
binary data. (The data for each input consists of two words.)
DRT1-compatible 1/100 display mode Not
supported.
Supported.
Unit power supply
Supplied from slice bus.
Supplied from communications
power supply.
Communications power supply current
consumption
None
70 mA max.
Connections
None
Poll, Bitstrobe, and COS/cyclic
Allocated I/O data
Default: Temperature data for 2 points
The Setting Tool can be used to allocate
the peak value, bottom value, top value,
valley value, rate of change, comparator
results, Status Flags, etc.
Default: Temperature data for 4
points
The DeviceNet Configurator can be
used to allocate peak value, bottom
value, top value, valley value, rate of
change, comparator results, Status
Flags, etc.
Node address setting
No setting required.
Set using the rotary switches or the
DeviceNet Configurator.
Baud rate setting
No setting required.
Automatically detected: Uses baud
rate set for Master Unit.
