12. Frequently asked questions
Access
Q: How many people can access the TH LINK via web at the same time?
A: Up to six people can access on the TH LINK simultaneously. Once a person logs onto the
TH LINK as an administrator, no one else can access it.
Time display
Q: I selected Yes in Use time server, but I always get a time stamp of the year 1970. Why is
that so?
A: It may be that the time server you set is not available from your network. Below the time
server setting there is a possibility to test the set time server by clicking on the respective
button. If no current date is displayed, please check your settings. If there is no time server
available from your network, you have the possibility to take over the computer system time
by selecting No for Use time server. Then click on the button Synchronize.
DPV1 and MPI master
Q: The adjusted baud rate is detected correctly, but there is no master displayed. Why is that
so?
A: The master is not shown because there has not been reference data exchange with the
other stations.
Slave
Q: Why are my slaves displayed as failed although they are working properly?
A: Check if you have changed the station addresses of the slaves. If you change addresses
(station addresses as well as TH LINK IP addresses) you have to restart the TH SCOPE
measurement so that the new network structure is detected.
Q: What does failure of a slave mean in the failure statistics?
A: In the failure statistics a slave is counted as failed if the slave cannot provide I/O data for
the master.
