DELTA LOGIC ACCON-NetLink-PRO User Manual page 49

Q: Sometimes MPI or PROFIBUS connections with high baud rates are
getting disconnected although the ACCON-NetLink-PRO compact is put
on the PLC and no other users are connected.
A: Be sure that the bus is correctly terminated. Even though the ACCON-
NetLink-PRO compact is the only device connected to the bus in
addition to the PLC. You have to insert the final resistor. Above all high
baud rates can be interfered.
Q: If I set the ACCON-NetLink-PRO 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: I enabled the RFC function the web interface and would like the
ACCON-NetLink-PRO compact to go on the bus using autobaud.
Unfortunately, the active LED just flashes but no communication is
possible via my visualization system.
A: Please deactivate the autobaud function in the web interface of the
ACCON-NetLink-PRO compact and set the correct baud rate with the
corresponding bus parameters.
Q: I have read that the ACCON-NetLink-PRO compact can communicate
with up to seven PCs at the same time. But I can't manage to query a
status of my automation system from more than six PCs at once.
A: A total of seven TCP connections are available that can be used at the
same time. However, please note that only up to six connections can be
used at once per type of connection (NETLink-S7-NET or RFC1006
connections are possible). The purpose of this is to keep one
connection channel free for the other protocol in each case.
Q: I am using the rack/slot mode of the RFC1006 interface and have
specified address 2 for my existing PLC in the web interface in »Fix
destination address for R/S mode«. Although the ACCON-NetLink-PRO
compact online is active (active LED lights up), my visualization system
tells me that no connection can be established.
A: Make sure you have assigned the correct values to rack and slot in the
parametrization. Look for chapter »8«.
