Network parameters are automatically set. This tab provides additional configuration for
advanced users.
Baud rate
The baud rate of the PROFIBUS network. The choices are 9.6 KBps, 19.2 KBps, 93.75 KBps, 187.5
KBps, 500 KBps, 1.5 MBps, 3 MBps, 6 MBps, 12 MBps. Default is 1.5 MBps.
Highest
Station
The highest possible station address for any active station on the network. This affects how much
time is spent soliciting for new PROFIBUS master devices. Default is 126.
Token
Rotation Time
The maximum target token rotation time for the network, expressed in t_bits (and milliseconds).
Time Sub-Tab of Network Tab
Slot
The amount of time (microseconds) the PROFIBUS master waits for a reply to a message.
Idle 1
The amount of time (microseconds) the PROFIBUS master waits after it receives a reply or an
acknowledgement.
Idle 2
The amount of time (microseconds) the PROFIBUS master waits after sending a message and
before sending another message.
Ready
The number of t_bits the PROFIBUS master waits before sending an ACK response, after sending a
command.
Quiet
The number of t_bits the PROFIBUS master waits after it turns on its transmitter, before it begins to
send data.
