Table 6.4.4:
Structure of pages 51...150
Bytes 0 to 7 contain the protocol information already mentioned above (refer also to page 48).
From byte 8 in the first segment (byte 2 in the following segments) the definition of the desired Tx-
identifiers is transmitted to the CAN gateway. For each Tx-identifier 6 bytes are required:
TxId_value
These four bytes specify the numeric value of the Tx-identifier.
The CAN-CBM-DP module with the order-no. C.2844.03 supports 11-bit-identifier:
0 ... 2047 (decimal).
The CAN-CBM-DP module with the order-no. C.2844.05 supports 29-bit-identifier, too.
form
Via this byte you can choose whether the output data is to be converted from Motorola
data format of the PLC into Intel data format of the CAN network or not. Byte
form
has
already been described in detail on page 29.
length
Here the number of data bytes of the Tx-identifier is specified. Entries between 1 and
8 are permissible.
