dde Link VBA instruction

KEN_KACEL · Jan 22, 2008

I resurrected a debugging tool for a job I did 3 years ago.
I have activeX buttons with some VBA code to select some PLC registers:
RSIchan = DDEInitiate("RSLINX", "FISH_FEED_X6")

The buuton keeps hanging up on this command.
What would of changed? I am usig RSLinx (CPR 9).
Would this have anything to do with it?

I have additional excell sheets for other projects that may not work?

RSIchan = DDEInitiate("RSLINX", "FISH_FEED_X6")

Try RSIchan = Application.DDEInitiate("RSLINX", "FISH_FEED_X6")
Make sure that "FISH_FEED_X6" is defined in RSLinx as a DDE Topic.

Tried : RSIchan = Application.DDEInitiate("RSLINX","FISH_FEED_X6")

No go...

There is an error message popup:

can't compile error
can't find library or project

I've had problems as such in the past. Check the linx activation hasn't been tampered with.

Do you have a topic in RSLinx defined as FISH_FEED_X6?

Another thought, what version of RSLinx are you using?

KEN_KACEL · Jan 22, 2008

rslinx 2.5 (cpr7)

The DDE links work when I paste the link into the cells on excell.
But does not work on my push buttons.

Is it Lite, OEM, Professional, Gateway?

KEN_KACEL · Jan 22, 2008

It is RSLinx Classic Gateway

What other software is involved?

I know that Micro$oft tends to change their Office software regularly. Is it a different version of Office? What about the security settings? Are macros possibly disabled?
