After writing a parameter, controller initialisation is carried out. During this tests are carried out as to
whether certain parameters match, e. g. whether the lo wer software end position is smaller than the
upper software end position. If an error is detected, an error message is generated and the CMAX
changes to fault status.
Activating block download can temporarily deactivate these tests. The controller only checks the
data when the block download has finished.

= 1: Start block download = 1: Block download active
= 0: End block download = 0: Block download not active
The controller is only recalculated after writing the block download = 0 (end block download)
While block download is active, start cannot be executed. Activating the block download is ended at
the latest when switching off the CMAX. In this case, controller recalculation is carried next time the
CMAX is switched on.
The controller can be enabled when block download is activated. However, the user must disable the
controller if he/she intends to write parameters that require this (2nd option set). If the controller is
disabled, it must not be enabled for as long as block download is active. This would otherwise lead
to E05 (in the event of enable, the project is not fully loaded or block download active).
If during establishment of the connection the FCT detects that block download is active and force
mode was active, it assumes that block download remained active unintentionally (as a result of
communication breakdown, program crash, computer failure etc.). FCT ends block download and
issues a message in the Output" window. This automatic termination of block download can be
suppressed by the PLC by setting CCON.LOCK = 1,
