and consumed alignment choice is Double Word alignment which is
enumerated as a 4. See the following table for valid alignment values.
Add I/O Module Configuration
If individual module configuration is required, it can be appended to
the configuration header. In the example shown below a 1734-OB4E module
is being configured. Byte 10 indicates that the data is to be sent to slot 2. Byte
11 specifies the size of the data as 8 bytes. Bytes 12 and 13 specify the OB4E
module configuration assembly instance 0x7B. The instance number is entered
in little endian (least significant byte first). In byte 16 the value of 7 indicates
that when the module is in Idle mode, Hold Last State should be enabled for
channels 0, 1, and 2 but not channel 3. If more module configuration is
needed, it could begin at byte 22 with the slot number of the next module to
be configured.
