3. Send the appropriate MB command. Use function code 16. Start at address 30000 and write to 2 registers
using the data in the array pump[]
MBB=,16,30000,2,pump[]
Results:
Analog output will be set to 0x40933333 which is 4.6V
Data Record
The DMC-40x0 can provide a binary block of status information with the use of the QR and DR commands. These
commands, along with the QZ command can be very useful for accessing complete controller status. The QR
command will return 4 bytes of header information and specific blocks of information as specified by the command
arguments:
QR ABCDEFGHST
Each argument corresponds to a block of information according to the Data Record Map below. If no argument is
given, the entire data record map will be returned. Note that the data record size will depend on the number of
axes.
