5-18 Operating Manual: PSS SB TESTER
Separate test: Testing the transmission rate
Abbreviation for this separate test in the “Device xx” window:
Transmission rate
Each device on SafetyBUS p is tested to ensure it has the correct
transmission rate.
In the detailed display of the result from this separate test, four pieces of
information are displayed: the lower limit, the upper limit, the measured
value and the result.
The limit values are pre-assigned for each transmission rate that can be
set on SafetyBUS p.
If the value measured for the transmission rate lies between the upper and
lower limit, the transmission rate is assessed as good.
Example: lower limit: 247.5 KBit/s
upper limit: 252.5 KBit/s
measured value: 250,000 KBit/s
result: OK
