Changing the Processor Module Type

If it is required, to change the type of Processor Module after the configuration has been finished already, it is possible to change the type of Processor Module later on. By this, all configurations of fieldbusses and interfaces that are identical on the new Processor Module are kept.

With Arithmetic Type item, processing of structured text can be modified.

With Only REAL arithmetic LREAL variables are processed as REAL variables (co-domain: 32 bit).

In general, we recommend to keep the default setting as this setting provides enough accuracy for code calculation.

For calculations which require a higher accuracy level, option Mixed REAL/LREAL arithmetic can be used, to extend calculation of LREAL variables to the extended co-domain of 64 bit.

Change to AC500 V3 PLC

By marking the checkbox Change to AC500 V3 PLC all V2 PLC project settings can be transferred to a V3 PLC.
