Rockwell Automation Publication 1769 UMOO06E EN P July 2013 9 Preface Notes 10 Rockwell Automation Publication 1769 UMOO6E EN P July 2013 Chapter 1 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 IMPORTANT For the 1769 L23E OBFC1B 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 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 rev

192. ystem clock timer 1 ys A timer is used to measure the time between two successive pulses The inverse of this value is the pulse interval rate The pulse interval rate cannot be read directly from the module It needs to be calculated The calculation can be performed in the user control program This method is not as accurate for higher pulse rates When the pulse interval shrinks two factors can distort the per pulse calculation If the pulse interval is close to the measuring timer s clock frequency 1 MHz the granularity of the time increments has a greater effect on rate inaccuracy In addition the rate can be calculated many times over the course of a single backplane scan As a result the rate data obtained at a backplane scan is only that of the very last pair of pulses and disregards the other rate calculations that have occurred during that interval This can result in rate inaccuracy if the pulses are unevenly spaced Cyclic Rate Calculation Method current rate The module continuously calculates rates for each of its four possible counters regardless of operational mode for example up down count The 32 bit signed integer rate from each counter is reported in the Ctr z CurrentRate words of the input array In this method the rates are calculated at the end of a counter s configured cycle time This is configured via the CtrwCyclicRateUpdateTime configuration word menu Valid entries are 1 32 767 ms The number of net
