To define the PLC addressing

Depending on the object type, some options will be disabled. Simply skip these steps in the procedure.

If the selected driver uses other terms than data group, word offset and bit offset, the driver-specific terms will be shown instead.

This makes it easier for you to define the PLC addresses, because the terms are now the same as in the PLC manufacturer’s documentation. However, if you want to show the default terminology, hold down CTRL when you select the driver.

To define PLC addressing

In the Atom group, select the atom you want to configure, for example, Actual Value for an analog object and select the appropriate I/O mode in the drop-down list.
In the PLC node for object group, select the PLC driver used and the relevant node number.
In the PLC address for <name> atom group, select the appropriate data group, word offset, bit offset and external type.
Dependent on the selected driver, the terminology may be changed. Data group, word offset and bit offset are the default terms.

When you define object templates, leave only the Bit Offset field open so that you only need to fill in the specific address for each object based on that object template.
