"Network variables '': No cyclic or freewheeling task for network variable
exchange found"
There is no cyclic or free-wheeling task resp. PLC_PRG in the project where the
network variables of type CAN or UDP of the given list are used (only declaration is not
sufficient!). You must take care that the variables are used in an appropriate task or in
PLC_PRG. If you want to use them in several tasks, regard, that at data exchange the
task with the highest priority will be regarded.
4602
"'': The object uses UDP port '' instead
of ''"
In the Settings of the named network variables list a port number is used which is not
the same as that which is used in the first network variables list found in the global
variables folder. Take care that all network variables lists are using the same port!
4604
"Network variables '': Base identifier has been used more than once."
The same COB-ID is used in the configuration settings of multiple Network Variables
lists. Assign unique IDs.
4605
"Network variables '': Duplicate CAN COB id."
In the configuration of a Network Variables list a COB-ID is used which is also specified
in the CAN PLC Configuration. Assign unique IDs.
4620
Unused variables have been found in the project. See the description for command
'Project' 'Check' Unused Variables.
4621
There are overlaps at the assignment of variables to memory areas via the „AT"-
declaration. See the description of command 'Project' 'Check' 'Overlapping memory
areas'.
4622
IEC addresses assigned to the same memory area are referenced in more than one
task. See the description of command 'Project' 'Check' 'Concurrent Access'.
