Which products are concerned?
ESP-HMI1-P (HMI Designer version 1.6)
What happens?
When compiling the HMI project, the following error message is indicated:
Exchange area addresses not correct
In the HMI Designer version 1.5, the same project could be compiled without any errors.
When does the problem occur?
Alarm or message areas evaluate the code area defined in the memory area bit per bit. For each bit a message can be defined which is indicated if the corresponding bit equals 1 (TRUE). Alarm and message areas are located in the status area of the project component exchange areas.
If two separated alarm or message areas access the same code area, an error message is tripped during compiling. It does not matter whether the same memory area is used for alarm or message areas or if several separated memory areas have been defined for this, but which access the same code or the same code area.
Example for an application:
In code C0150 (status word of the controller), some bits are to be indicated as alarm messages (TRIP) and some as information messages (CINH).
Possible diagnostics?
None
Short-term measures/recommendations?
Do not use the same code area for different alarm or message areas.
Evaluation:
The same code area is rarely used for alarms and messages (information messages).
