Which products are affected?
ESP-DDS2-P (Global Drive PLC Developer Studio Version 2.0)
What happens?
In the Parameter monitor (Resources tab) code C65635 is the last code in the directory Code list. If that code is updated by the Parameter Monitor, the following error message is displayed:
Read error at code: C65535. Code doesn't exist.
When does the problem occur?
In the Instance parameter manager (Resources tab) a code can be created for a variable in which no code number is defined in the field Code/Index. That is, a code can be defined without a code number. This can be used for the initialisation of variables, e.g. variables in Lenze function blocks.
All codes which have been defined in this way are given the code number C65635. Although this code is in the Parameter monitor, its value cannot be displayed or changed.
In the software Global Drive Control (GDC) and on the keypad (EMZ9371) this code is not displayed.
Possible diagnostics?
None.
Short-term measures/recommendations?
None.
Evaluation:
Inasmuch as no code number has been defined for a code, its value cannot be displayed or changed by the Parameter monitor.
