Operating Instructions, 03/2022, A5E39895388-AC
Dependency of the PN/CAN LINK state from the status of the PROFINET connection and from the
state of the S7 controller
Event
Reaction
PN/CAN LINK has never been
connected to the S7 controller or
has not yet been configured since
boot-up
PN/CAN LINK state is "OFF"
S7 controller connected / not yet
completely configured
The PN/CAN LINK receives the necessary configuration data from
the S7 controller.
For the "receive message modules" the input data is preassigned
according to the parameter assignment.
PN/CAN LINK state is "OFF".
S7 controller connected /
completely configured / no cyclic
PROFINET data exchange or data
from the S7 controller has IO
provider status "Bad"
PN/CAN LINK state is "OFF"
Cyclic PROFINET data exchange is
active and data from the S7
controller has IO provider status
"Good"
PN/CAN LINK goes to the state conforming to the control bits
("OFF" or "ON"). The control bits are contained in the cyclic data
that come from the S7 controller.
S7 controller changes to STOP
PN/CAN LINK state is "OFF"
S7 controller changes to RUN
PN/CAN LINK goes to the state conforming to the control bits
("OFF" or "ON"). The control bits are contained in the cyclic data
that come from the S7 controller.
Termination of the S7 connection
(after the PN/CAN LINK has been
configured once by the S7
controller)
PN/CAN LINK state is "OFF"
Reconfiguration by S7 controller The PN/CAN LINK receives the necessary configuration data from
the S7 controller.
For the "receive message modules" the input data is preassigned
according to the parameter assignment.
PN/CAN LINK state is "OFF".
