Error-free data transmission from the CP52IO GDM interface module
H5
No ramp-up ID from the CP52IO GDM interface module
H6 Off Clock trigger and base sampling time are parameterized and have send
authorization from CP52IO
On The clock trigger and basic sampling time have been parameterized for
transmission but have no transmit authorization from the CP52IO (priority
logic is inhibiting one of the two signals)
