Title: More H0-CTRIO2 Math w/ DLO5
Post by: sgsims on April 17, 2014, 12:11:07 PM: Since the DL05 can't do Binary Math I am converting the Binary output from the CTRIO to BCD....so far so good. What happens when the binary count from the CTRIO gets out of the BCD range? Will CTRIO will continue to count up to the full range of a binary double word before rolling over to 0? If so I guess I need to figure out a way to soft reset the CTRIO count before it gets above 99999999 or all my math will fall apart.

I guess I should be using the scaling feature of the CTRIO to scale to a BCD format.

Post by: sgsims on April 17, 2014, 02:27:50 PM: Your question got me thinking...I was thinking I needed to use the ADDBD instruction to add a constant to by DWORD Value being mapped from the CTRIO. My constant value is 200 so can I do this?

LDD - V2000
ADDB - Kc8
OUTD - V2002

I tried this using a DL06..don't have a DL05 here in the office. Seems to work.
