bgscott_479,

I used your starting addresses and the CTRIO worked OK. I used V2050 for input starting address, V2100 for output, and V2150 for register. I'm only using 1-channel. V2050-2051=current count. I could not get your example code to work, see your example rung #6. Hope this helps.

I used the following:

STR SP0

LD K4

OUT V2150

LD K0

OUT V2101

// Rung 2

STR SP0

LD K1

LD K8

LD K80

WT V2150

// Rung 3

STR SP1

TMRF T0 K5

// Rung 4

STRPD T0

OUT B2130.7

// Rung 5

STRN B2074.6

AND B2074.7

RST B2130.7

// Rung 6

STR TA0 K10

LDD V2050

OUTD V2152

I have written a program that uses a HS counting card in an 06 to count encoder pulses. I really need to be able to kill the power to this program for short times without losing the count on my encoder. I found an example on AutoDirects web site that works through retentive memory to do this, but I have already used a ton of the V memory addresses that they use for an EZtext panel. the name of the example is 250_CTRIO_both_channels_retentive. Can anyone look at this and tell me how to make it work if my first input address needs to be V2050 instead of V2000? I don't understand the addressing well enough to figure it out. attached is the program:PLC 06

// Rung 1

// Address 0
