Hello,

I am getting the alarm 12550 "EXTOPEN not defined or option not enabled" when I try to run my program containing the command EXTOPEN. Can someone help?

HI,

It might help to give the line of code you are using.

EXTOPEN(<error>,"<ExtG>",<machining mode>,<usage mode>,
<write mode>)

12550 is a general message when the system doesn't recognise the word as a function or a variable. It's not an option so the syntax is probably wrong

Here is the text of my command

EXTOPEN(error,MFILENAME,"SYN","SHARED","OVR") 

Where MFILENAME is defined as  "/dev/ext/1"

Hi,

Just looked at the 2009 doconcd and there is no mention of extopen. Latest Sinutrain works OK but I think maybe your system is a power line and it's not implemented.

It is an 840Dsl.

Would this alarm appear if I made a mistake in my extdev.ini?

What version of Operate are you using?

I don't think EXTOPEN was supported until version 4.5
