Technical data

Special features:
With this type of communication, the base interface is always used. Data is
only transmitted when the status of bytes has changed. If you use GP,
global objects must also be configured on the CP as well as the
input/output bytes.
☞
Configured I/O bytes must not overlap the addresses of
inserted I/O cards.
