Using the control panel
The current version of the control panel only supports one method of upload and download.
The function DOWNLOAD APPLICATION is not currently available.
UPLOAD: This function transfers the parameter set from the DCS800 drive to the control
panel. It is done as follows:
1. Put the drive in "local mode" by pushing the LOCAL REMOTE button on the control
panel.
2. Select PAR BACKUP from the main menu (use the arrow button to find it), then
UPLOAD TO PANEL. If the control panel reports an error "Parameter Upload
Failed," the you probably did not do step 1.
DOWNLOAD: This function transfers the parameter set from the control panel to the
DCS800. It is done as follows:
1. Put the drive in "local mode" by pushing the LOCAL REMOTE button on the control
panel.
2. Select PAR BACKUP from the main menu (use the arrow button to find it), then
DOWNLOAD FULL SET. If the control panel reports an error "Parameter Download
Failed," the you probably did not do step 1.
NOTES: 1) You must first do an UPLOAD before this function appears. 2) The
function DOWNLOAD APPLICATION is currently not available.

Adaptive programming

_________________________________________________________
Overview
This section contains some helpful hints about how to use adaptive programming.

Using spare control bits

Many times with adaptive programming, a bit in a control word needs to be set. This could
be a defined control bit or a spare control bit. The MainCtrlWord (7.01) has 11 defined bits,
from bit 0 (OnOff1) to bit 10 (RemoteCmd). The last five, B11 through B15 are spare,
available for use by the AP program. More often than not, it is better to use a spare control
bit than a defined control bit. If you use a defined bit, one never knows whether it will be
written over by the firmware, undoing the work of your AP program.
the start/stop functions in group 10, including direction, reset, handauto, Off2, and E-stop,
can be set to switch on one of these spare bits.

The importance of BSet (Bit Set)

Setting and clearing a bit in a control word is done by use of the BSet function block. If
BSet is not used, instead of switching just one bit, the AP program will likely switch all the
