Communication / CBC
NOTE
8.4-44
P721 (CB parameter 11)
Formula for calculating the baud rate from the constants:
time quantum = tq = (BRP+1) * 2 * tClk
Clock Period = tClk = 62.5 ns (at 16 MHz)
Synchronization segment = tSync-Seg = tq
Time Segment 1 (before scanning time) = tTSeg1 = (TSEG1+1)*tq
Time Segment 2 (after scanning time) = tTSeg2 = (TSEG2+1)*tq
Bit time = tSync-Seg + tTSeg1 + tTSeg2
The parameter value corresponds to the value of the bit timing register of the
CAN component. A more exact description of this bit timing register can be
found in the manual of the CAN module of the C167CR or in the manual of
the component, INTEL 82527 (extended CAN).
P918.1 (CBC bus address)
Here, the node address of the unit on the CAN bus is set. It is included in the
calculation of the CAN identifier for parameter tasks and replies (PKW task /
PKW reply) and process data (PZD-receive / PZD-send). (See also P711 /
P696, P712 / P697 and P713 / P698).
When the above settings have been made, the CBC is regarded as
registered in the converter and is ready for communication via the CAN
bus.
Changing parameters or specifying process data via the CAN bus
is not yet possible after this step.
Parameterization must first be enabled and the process data still have
to be softwired in the converter.
P706 (CB parameter 11)
Baud rate = 1 / bit time
