Sequence Of Operations For Starting Up Devicenet Boards (Cbd) - Siemens 6RA7086-6KS22 Operating Instructions Manual

Start-Up
7.7.7

Sequence of operations for starting up DeviceNet boards (CBD):

With the power supply switched off, insert the board or adapter board with board in the slot.
1
Please note that slot 2 (on right) must always be occupied before slot 3 (in center) can be
used.
Wire up the DeviceNet using appropriate cabling (see below for details of cables).

The following parameters are relevant with respect to communications. Index 1 of the
3
relevant parameter applies to the 1
communication board (2
U711 CB parameter1
-
-U712 CB parameter2
-
U711 and U712 can be parameterized independently of one another. The first 4 PZD
words (produced data) are always sent after a request from the master.
-U720 CB parameter10
-
- U722 CB/TB telegram failure time
P918 Bus address
-
P927 Parameterizing enable (necessary only if parameter values need to be altered via
-
The process data of the 1
-
appropriate connectors or binectors (see Section 8, function diagrams Z110 and Z111).
For meaning of the control and status word bits, see Section 8, Sheets G180 to G183.
Switch the electronics power supply off and on again or set U710.001 or U710.002 to "0" to
4
transfer the values of parameters U712, U720, U722 and P918 to the supplementary board.

CBx):
Definition of number of words in the process data area that the SIMOREG sends as
a response to a request by the master (produced data). The following options can be
selected:
U711 = 170 ... 4 PZD (status word and actual values)
U711 = 171 ... 8 PZD (status word and actual values)
U711 = 172 ... 16 PZD (status word and actual values)
Definition of number of words in the process data area that SIMOREG expects to
receive after a request from the master (consumed data). The following options can
be selected:
U712 = 120 ... 4 PZD (control word and setpoints)
U712 = 121 ... 8 PZD (control word and setpoints)
U712 = 122 ... 16 PZD (control word and setpoints)
Definition of the DeviceNet transmission rate. The following options can be selected:
U720 = 0 ....... 125kbaud
U720 = 1 ....... 250kbaud
U720 = 2 ....... 500kbaud
Definition of the time period within which at least 1 telegram with PZDs must be
exchanged before a fault message is generated.
This parameter should be set to "0" first (monitoring function deactivated). Once the
network is operating correctly, a time value can be set within which PZDs are
normally exchanged.
Definition of DeviceNet MAC ID for the CBD in the 0 to 63 range.
