Pictory e02.json export template questions

Post by RR4711 »

Hi,
I just made a new project with a RevPi Connect 32+, a DIO and a AIO. I export all variables in the configuration to get an offset list for my C code accessing the process image via an overlayed C structure.
(I export the configuration as "offset list" using the e02.json template via the export menu.)

I get this:

Code: Select all

InputValue_1		 0	 //INT P1000 goes here (Range 10V for safety reasons!) 
InputValue_2		 2	 //INT  
InputValue_3		 4	 //INT  
InputValue_4		 6	 //INT

RS485ErrorLimit2		 211	 //WORD  

Where does the ##ATTR_COMMENT## come from, and is this actually an indication that this offset is not run-time accessible, but set only during the module configuration by the driver (as it appears to me)?
Can someone confirm this is the case?

Is there a way of writing an own template file to directly generate a C structure declaration?
Right now it's very tiresome work doing this manually.

Hi Markus, this is a feature that has minimal documentation. Have a look here:

So the best way is to take copy and modify an existing file - here is the list:

Code: Select all

pi@RevPi40302:~ $ find /var/www/pictory -iname e0*.json
/var/www/pictory/resources/data/patterns/export/e04.json
/var/www/pictory/resources/data/patterns/export/e02.json
/var/www/pictory/resources/data/patterns/export/e03.json
/var/www/pictory/resources/data/patterns/export/e01.json
It seems that you are right with the assumption that the "##ATTR_COMMENT##" variables are not run-time accessible.
I'll try to clarify this.
just an idea - the RevPiModIO Python library might be a better starting point a it parses the PiCtory configuration and creates a mapping.

Yeah wel OK, but I like my C better :-)

Hi well I have some news about it:
##ATTR_COMMENT## is filled from the 'comment' value of the field in the RAP file
Example from the RAP file: RevPiAIO_20170301_1_0.rap
"name": "Input2Range"
"comment": "You must use wire bridges for current measurement!"

I just can say that "MEM" variables are NOT runtime accessible. I.e. look at a Virtual Modbus TCP Master in PiCtory:
2020-11-25 16_38_31-PiCtory - 1.4.3.jpg
2020-11-25 16_38_31-PiCtory - 1.4.3.jpg (9.79 KiB) Viewed 2960 times
There are those two MEM variables:
2020-11-25 16_38_04-PiCtory - 1.4.3.jpg
2020-11-25 16_38_04-PiCtory - 1.4.3.jpg (8.14 KiB) Viewed 2960 times
