Good day Roger,

The DT800 and other DT800's refuses to make a folder <B> in its internal memory and on the flash card. The folders of all other schedules were made though. If I load another program into memory, there is no problem, but I cannot find the problem. Can you help?

Kind regards,
Gerben

If you say this happens on more that one DT800 unit, I suggest you might need to post the code for review.

If it sensitive and you don't want it out in the open, maybe just email it to the DT support address so Roger or one of the boys (and/or girls?) can review in the depths of the DT laboratory.

Good day Supermono,
Here is the schedule <B> code. The total code would be too long to display here. If you need more I will send it to you by email.
Regards, Gerben

Dear Supermono and/or others,

Today my local supplier called me and helped me to tackle the problem. The problem was that IF-statements themselves are not able to log the values of the variables (comparable with ALARM-statements).

He suggested to put extra lines in between the IF-statements with which the variables can be logged. Apparently the <B>-folder will only be created in case of logged data. The folder will also be created if there is logged data present in the code but in the schedule definition is set as non-logging.

It will not be created if there is no logged data present even though the schedule is marked as "logging".

Thanks for your time!

Kind regards, Gerben

Yes that is correct.

An 'IF' is like an ALARM in that it has a test against conditions and an output, but is never logged.

So by adding logged channels in between the statements you might have something like this:

IF(1CV<1)AND
IF(41CV>1)"ERR_Lit_Ref"{[131CV=131CV+41CV]}
131CV
IF(2CV<1)AND
IF(42CV>1)"ERR_Lit_SltRef"{[132CV=132CV+42CV]}
132CV
IF(3CV<1)AND
IF(43CV>1)"ERR_Lit_Buf5"{[133CV=133CV+43CV]}
133CV
IF(4CV<1)AND
IF(44CV>1)"ERR_Lit_Slt5"{[134CV=134CV+44CV]}
134CV
IF(5CV<1)AND
IF(45CV>1)"ERR_Lit_Buf3"{[135CV=135CV+45CV]}
135CV
IF(6CV<1)AND
IF(46CV>1)"ERR_Lit_Slt3"{[136CV=136CV+46CV]}
136CV
141CV("Reset ERR_Trig",NL)=0
