Parameter Description
Execution Order for Block
This is the address of the
selected Rack.
Address of selected I/O
module (must match model
selection guide)
Channel on selected I/O
Module
High Range Value Engineering
Unit - value of input that
corresponds to 100 % output
value
Low Range Value Engineering
Unit - value of input that
corresponds to 0 % output
value
Value of mA output that
corresponds to 100 % output
signal (for example: 20 mA)
Value of mA output that
corresponds to 0 % output
signal (for example: 4 mA)
Value of mA that you want to
set the High Range Limit
Value of mA that you want to
set the Low Range Limit
Failsafe Value
Type of Failsafe
Slew Rate is the maximum rate
of change required to drive the
output from full OFF (0% -
typically 4 mA) to full ON
(100% - typically 20mA). The
Value or Selection
Read Only. To change
block order, right-click on
