Manufacturer’s Status Register
The Manufacturer’s Status Register reflects the present fault flags. Each fault
has its own bit in the Status Register. Unlike the LED Status of the Emergency
Message, which can only relay the highest priority fault, the 16-bit Status Register
will show all present faults. See Section 6: Diagnostics and Troubleshooting for
descriptions and probable causes of the faults.
Store Parameter Object
The 1356 /1356P has three parameter blocks: the Normal parameter block,
Back-up parameter block, and Factory parameter block. An SDO or 1313/1314
programmer Write operation will update the parameter in working RAM. All
parameters in working RAM will be saved to the Normal parameter block after
KSI cycle.
The text string “bkup” initiates a complete storage of all parameters to the
Backup parameter block.

BACK_UP_COMMAND
“bkup”
WO
Text string that commands all
0x70756B62
parameters to be saved from
working RAM to the Backup
flash space.
At first glance, the ASCII looks “backward.” This is because CANopen
defines that the LSB goes first and MSB is sent last. Therefore “bkup” (which is
data bytes 5, 6, 7, and 8) is written as “pukb” when converting it to hex (data
