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–IXE/D
module:
•
type of input
•
one or two input types
•
o C or o F
•
data format
•
real time sampling
•
alarming
•
calibration
Configure your module for its intended operation by means of your
programming terminal and write block transfers.
Note: Programmable controllers that use 6200 software
programming tools can take advantage of the IOCONFIG utility to
configure this module. IOCONFIG uses menu–based screens for
configuration without having to set individual bits in particular
locations. Refer to your 6200 software literature for details.
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–IXE/D will respond with the Series A default value of 27.
