Cause
At a PLC connection point an address is defined that is not located within the address range of the associated PLC card.
Solution
- Locate the PLC connection point in the schematic using the Go to (graphic) functionality that is provided by the popup menu of the Message management dialog.
- Jump via the popup menu item Go to (counterpiece) of the PLC connection point to the associated PLC box of the PLC card.
- Launch the property dialog of the PLC box.
- Determine the values entered in the property list of the first tab in the field Start address of PLC card and PLC device: Data length (...).
- Change either the PLC address of the PLC connection point so that it is located within the address range of the PLC card, or adapt the start address or the data length at the PLC box accordingly.
- Confirm your entries.
- Then start a new check run.
Notes:
This check run checks whether the address of a PLC connection point is located within the address range of the associated card (from = "start address", to = "start address + data length").
The following conditions must be met so that the check run can be executed:
- The PLC connection point disposes of one of the function definitions "PLC connection point, AO", "PLC connection point, AI", "PLC connection point, DQ", "PLC connection point, DI" or "PLC connection point, multifunction" with matching logic. The identifier of the addressing for inputs and outputs is not a decisive factor for the check.
- The PLC address of the PLC connection point may not be empty.
- For the PLC connection point an associated PLC box with the properties Start address of PLC card and PLC device: Data length exists. The corresponding fields must be filled with a value and both pieces of information must be set to match the I/O type and the index of the PLC connection point to be tested.
- The value of the property CPU name[1] may not be empty. This entry determines the address scheme to be used.
- In the PLC-specific settings of the address scheme belonging to the CPU a counter with the configuration value "Start address of PLC card" must be defined.
In addition the following applies for the check run:
- Without specification of an addressing scheme the address range (to = "start address + data length") cannot be calculated.
- The data length is specified independent of the addressing scheme used as decimal value in bits.
- The data length can be stored in the parts management and applied from there.
