Again, you need to check whether the reason for the error can be found at the modules or the bus cables. This test reliably detects
weaknesses inside an installation and will find all problems. The disadvantage is, you will always find only one problem after the other -
this can take a long time.
Note
Both tests have their specific advantages and disadvantages. The send test coming with a ring cabling will show the general behavior
and conveniently, but can only be used to find failures moderate system failures as well as broken single modules. The same test
coming with a simple cabling method without a ring topology can then be used to find all problems but only the first issue in a row.
In combination, technicians can first ensure basic operations and guarantee basic availability.
The Receive Line Test
While the Send Line test will take care for general availability of modules and helps to find cabling issues, the Receive Line Test will
take care for the quality of the data signal that will reach the BACS Bus Converter:
In some cases, the cabling is well done, but the communication does not start or interrupts sporadically. This may cause as an example
by strong electromagnetic interferences: EMI – In this case, the signal itself will be compromised by electromagnetic fields that will harm
the conductor inside the cable and produces error bits that cannot be compensated. With the receive line test, you can take a look what
happens if the last module far away from the BACS Webmanager will send a data package.
Preconditions of the test
Please note that all modules must use the ID "0"! Otherwise this test will not work properly. If in doubt, use the Automatic Mode to set
all modules to the ID "0" in advance. After resetting, proceed to the receive line test
