Title: Counter Bit Question?
Post by: jbullock on March 28, 2019, 01:29:55 PM

MicroLogix has a count up or down enable bit (e.g. C5:3/CU). Does Do-More designer have the same thing (e.g. CT0.CU)?

Just as a reference in AB the .CU bit is the memory bit for the one shot operation of the counter. It is present in the counter structure. Incidently the AB structure alson contains a .CD bit which is used when the counter is a 'down counter'. So two separate instructions can address the same structure and thus form an up/down counter.

The help file for the Do-more does not show a similar bit in the counter structure and I believe it is a part of the individual counter instruction. As such it is probably not addressable.
