A 7I89 with all encoders having only 'A' pins
would give you 24 channels of frequency counters if thats whats required. You could also have a mix of normal encoders for normal motion use and 'A' only ones used just for frequency counting.
That would be a really nice solution. I could use a 7i80DB (I'm not sure the 7i92 can be connected to the 7i89) to interface with the 7i89.
A regular (non-T) 7I92 may be too small to fit all 24 counters But I can see what fits. What 7I80DB model do you have? (-16 or -25)
Is there a firmware already available for the A input only encoders? Generally, yes. Specificall for the 7I89, no What other I/O do you need in the configuration? El mi??, 4 dic 2024 a las 18:10, Peter Wallace (<[email protected]>) escribi??:

You could also have a mix of normal encoders for normal motion use and 'A' only ones used just for frequency counting. How many encoders fit in the firmware depends on the FPGA size so this is still TBD especially on the smallest (XC6SLX9) FPGAs Peter Wallace Mesa Electronics _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
