I’m getting a bit confused on how Siemens strings work in Ignition.
In my Ignition project I’m correctly reading few strings from a S7 Siemens PLC.
Some of them are good, others are shown blank even if there is something at the PLC (and have no errors in Ignition).
Comparing the two strings (the one I can read and the blank one) I’ve noticed that the first two chars of both strings are different.
Below the chars at the PLC (as HEX)
The correct one has
B#16#0F (this can be different for other working strings)
B#16#53 - start of the string
The one showing blank has
B#16#12 - this char seems a bit odd
B#16#48 - start of the string
Do you know if there is any reason why the second one is blank?
Any easier solution instead of using Chars and putting together the string with a script?
