Functions
4.2 CAN transparent
Dependency of the PN/CAN LINK state from the status of the PROFINET connection and from the
state of the S7 controller
Event
PN/CAN LINK has never been con-
nected to the S7 controller or has not
yet been configured since boot-up
S7 controller connected / not yet com-
pletely configured
S7 controller connected / completely
configured / no cyclic PROFINET data
exchange or data from the S7 control-
ler has IO provider status "Bad"
Cyclic PROFINET data exchange is
active and data from the S7 controller
has IO provider status "Good"
S7 controller changes to STOP
S7 controller changes to RUN
Termination of the S7 connection (after
the PN/CAN LINK has been configured
once by the S7 controller)
Reconfiguration by S7 controller
44
Reaction
PN/CAN LINK state is "OFF"
The PN/CAN LINK receives the necessary configuration
data from the S7 controller.
For the "receive message modules" the input data is preas-
signed according to the parameter assignment.
PN/CAN LINK state is "OFF".
PN/CAN LINK state is "OFF"
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.
PN/CAN LINK state is "OFF"
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.
PN/CAN LINK state is "OFF"
The PN/CAN LINK receives the necessary configuration
data from the S7 controller.
For the "receive message modules" the input data is preas-
signed according to the parameter assignment.
PN/CAN LINK state is "OFF".
