I have a little issue with writing strings to a Siemens S7-300.
Writing and reading int in the same DB works great. Changing the string in the plc updates the string in Ignition, but when we try to write back to the PLC nothing happens in the PLC. Ignition keeps the new value. Nothing in the logs.
writes '90-1-1' directly to the plc, ignition reads this value. Writing '91-1-1' to the tag, no change in plc, ignition keeps displaying this value until we change the string in the plc. Can this be plc related?
On your picture on the right side where it says Last published value there is a date and time as value...
(then is the quality: Good and then the timestamp)...
