Module Overview
The 1769-HSC module is an intelligent counter module with its own
microprocessor and I/O that is capable of reacting to high-speed input signals.
The module can interface with up to two channels of quadrature or four channels
of pulse/count inputs. The signals received at the inputs are filtered, decoded,
and counted. They are also processed to generate rate and time-between-pulses
(pulse interval) data. Count and rate values can then be used to activate outputs
based on user-defined ranges.
The module counts pulses at up to 1 MHz (250 kHz for the packaged
controllers) from devices such as proximity switches, pulse generators, turbine
flowmeters, and quadrature encoders. The module has four on-board, high-speed
switching outputs. These outputs can be under user program or direct module
control, based on the count value or frequency.
The 1769-HSC module is compatible with MicroLogix 1500 packaged
controllers (1764-LSP/C and 1764-LRP/C modules, firmware revision 6.0 and
later), CompactLogix controllers (generic profiles required for firmware revisions
prior to 11.0), and the 1769-ADN/B DeviceNet adapter.
IMPORTANT
For the 1769-L23E-QBFC1B and 1769-L23-QBFC1B packaged controllers
HSC functionality, there is no processing to generate rate or time-
between-pulses data. Only count data is used to activate outputs based
on ranges.
