8.12.1 Access to PLC data
For ToolsTalk to be able to move around variables in the PLC, Fieldbus variables should be placed in a
group called
Fieldbus_Variables and shared variables in a group called Shared_Variables . Placing
variables in other groups will result in them not being possible to map for a fieldbus in ToolsTalk. Shared
variables must also carry the prefixes “SI_” or “SO_” in order to be mapped by the fieldbus form.
