Technical data

Input fields
Cumulative topology info:
No. of remote
active stations
The number of active stations not included in the
topology file. These are normally stations of other
manufacturers. This parameter is required to calculate
the bus parameter field. (Range of values: 0..(HSA
(number of configured active stations.))
Highest station
address (HSA):
Highest Station Address, specifies the highest station
address of an active station in the bus system.
Addresses for passive stations can be higher than the
HSA (range of values: highest active address in the
network .. 126).
Bus parameters:
Data rate: Data rate on the bus (range of values: 9.6 Kbps, 19.2
Kbps, 93.75 Kbps, 187.5 Kbps, 500 Kbps and 1.5
Mbps).
Default SAP: If an L2 frame is received without a destination SAP
number, the CP automatically selects the default SAP.
Maximum no. of
retries
Call repetition counter for unsuccessful transmission. It
specifies how often a call is repeated by the initiator
when no correct acknowledgment frame has been
received (range of values: 1 to 8).
Medium
redundancy:
(Range of values: no redundancy)
Bus parameter data:
Slot time (TSL): Monitoring time during which the transmitter (initiator) of
a frame waits for an acknowledgment from the
responder. When this time elapses, transmission is
repeated according to the "maximum no. of retries"
value (range of values: 80 to 4095 bit times, however at
least 2 ms!).(see Table 6.1).
