Q: It is not possible to go online when the adapter is put on the
PROFIBUS.
A: If possible use the autobaud function. If not desired or possible you
have to check the PROFIBUS' timing parameters in the STEP7 project
planning. Via the »Bus Parameters« button you can enlist the read
off values into the extended bus parameter settings. You have to
increase the »TRT« (Target Rotation Time) parameter in the
ACCON-NetLink-USB compact as well as on the PLC.
Q: If I set the ACCON-NetLink-USB compact to autobaud in the PG/PC
interface and try to go online, the active LED lights up briefly before a
message appears telling me that the bus parameters cannot be
determined.
A: Please deactivate the autobaud function in the NETLink-S7-NET
driver (PG/PC interface) and set the correct baud rate and the
correct profile.
Q: If I open various connections via the STEP7 driver, the connection
sometimes breaks off or error messages appear saying that it is not
possible to establish a connection.
A: For the communication with S7-300 modules it may be necessary to
parameterize the communication resources.
You can influence the assignment of existing »Connection
Resources« under object properties of the CPU in the hardware
configuration.
