Hi All,
I currently have a setup using a CLX PLC and a standard Panelview communicating over devicenet. The Panelview displays the current family name (See attachment Family name display).
This is done using an embedded variable where an ASCII string is defined like /*A:9 family_name*/. I have read the help file and I understand that the defined format denotes the start of an Ascii tag of length 9 and tag family_name.
I can see in the panelview tag editor that this tag "family_name" is of type character array with a length of 10 and has address 0:2 over the DNET IO slave. However I don't fully understand how this technique works and how the family name is updated.
I have read the help file and it suggests that there will be a string in the processor that will hold a string array containing Ascii characters of SINT data type. However I cannot find any such string in the controller tags and hence I am a little bit stumped on figuring out how this is done.
I have attached some pictures showing panelview and controller tags that might help explain.
Thanks for any help in advance.
Regards,
Donnacha.
