Module Configuration
In this chapter you will read how to configure your module’s hardware,
condition your inputs and enter your data.
Because of the many analog devices available and the wide variety of possible
configurations, you must configure your module to conform to the analog
device and specific application that you have chosen. Data is conditioned
through a group of data table words that are transferred to the module using a
block transfer write instruction.
You can configure the following features for the 1771–IXHR module:
type of input
one or two input types
X10 magnification for millivolt data
o C or o F
real time sampling
millivolt bias level (zoom mode only)
input filtering
alarming
calibration
Configure your module for its intended operation by means of your
programming terminal and write block transfers.
During normal operation, the processor transfers from 1 to 27 words to the
module when you program a BTW instruction to the module’s address. The
BTW file contains configuration words, high and low channel alarm settings,
and calibration values that you enter for each channel. When a block transfer
length of 0 is programmed, the 1771–IXHR will respond with a default
value of 27.
This module is permanently configured to accept and report data in 2’s
complementary binary format only. It is not recommended for use with PLC–2
family programmable controllers.
