Can't upload strategy

groov EPIC
1

I am finally getting around to porting my snap-pac system over to an EPIC controller. Just to get my feet wet, I am trying a single simple chart that was imported from Pac Control 9.6. Everything imported (seemingly) fine and I have added the EPIC controller as a control engine. The EPIC is currently running as a groov box and that part works fine. The controller section is turned on.
When I try to upload/Debug the strategy I get an error.
“Empty stack error.” Code: -60
What is going on here?
EPIC%20error

Just to be clear, you are running in PAC Control 10.2 right?
If you do a Compile all, do you get any errors?
Are there any PID loops in the strategy?

EDIT. Digging into that error number some more… Looking at page 385 of the PAC Control users guide it states to contact support if you get that error.

Yeah, no PIDs, just a simple turn on/off kind of routine. PAC Control 10.2d
No compile errors.
See attached strategy. I’ll send a support request.

Just a follow up.
I got it working by loading an empty strategy and then loading my actual strategy.
Support was quick to respond and had a couple other ideas, but I ended up not needing them.

I recently had the same issue. My PAC Control program would not upload and the Opto Error was Code -60.

I tried loading an empty strategy. The strategy loaded fine, but when I went to load the other strategy again it would not upload.

I ended up having to create a new strategy and import charts and include the subroutines from the strategy that would not upload. This worked and allowed me to upload. Unfortunately I had to recreate some of my groov View variables as they did not import when I imported the charts.

I believe the the strategy that would not upload was somehow corrupted…

Hello,

Just a foreword, I wasn’t able to get screen shots of this problem, I’m having a similar issue.

I haven an EPIC running a strategy, If I make a change to the strategy then upload the first time always is successful. But occasionally, after upload, I’ll notice there is a small issue that needs fixing, a couple of lines get a small edit. If I upload the modified strategy, in less than, say, 10 min of the first upload, there is an onslaught of errors - screen shots would have been convenient for this, apologies. The resolution that I’ve found is disabling PAC controller, then re-enable. Sometimes doing this works, other times it doesn’t. Is there a background process after an upload that I’m stepping on by uploading shortly after? Sorry for how vague this is. If there a repeat offence I will grab photos.

Thanks, Dan
