Causes
- The required value is missing at the Start address of PLC card properties at a PLC box that only has inputs or outputs.
- In the case of a PLC box that disposes of inputs and outputs, the required value is missing at the Start address of PLC card and/or the Start address 2 of PLC card properties.
- The required value is missing at the PLC subdevice x: Start address (inputs) properties at a PLC box that disposes of inputs at the PLC subdevice x.
- The required value is missing at the PLC subdevice x: Start address (outputs) properties at a PLC box that disposes of outputs at the PLC subdevice x.
("x" designates the number of the PLC subdevice 1 to 12. At the PLC connection points, the PLC subdevice: Index property specifies to which subdevice of the PLC box the PLC connection points belong.)
Solution
- Locate the PLC box in the schematic using the Go to (graphic) functionality that is provided by the popup menu of the Message management dialog.
- Open the property dialog of the PLC box.
- Bring the first tab to the front.
- In the properties table fill in the value fields of the properties Start address of PLC card for inputs and Start address 2 of PLC card for outputs in accordance with the conditions described above under 'Cause'. Or fill in the value fields of the PLC subdevice x: Start address (inputs) or PLC subdevice x: Start address (outputs) properties.
- Click [OK].
- If required, start a new check run.
