The incremental encoder module is configured using a group of data
table words that are transferred to the module using a block transfer
write instruction.
Some of the software configurable features available are:
•
number of inputs
•
encoder multiplier
•
gate function
•
latch function
•
rollover
Configure your module for its intended operation by means of your
programming terminal and write block transfers.
Note: Programmable controllers that use 6200 software (release 4.2
or higher) programming tools can take advantage of the IOCONFIG
Addendum utility to configure this module. IOCONFIG Addendum
uses menu–based screens for configuration without having to set
individual bits in particular locations. Refer to your 6200 software
literature for details.
Important: It is strongly recommended that you use IOCONFIG
Addendum to configure this module. The IOCONFIG
Addendum utility greatly simplifies configuration. If
the IOCONFIG Addendum is not available, you must
enter data directly into the data table. Use this chapter
as a reference when performing this task.
