6.12 System settings for power up, RESET and part program
start
The behavior of the control after
S Power up (POWER ON),
S Reset/part program end
S Part program start
can be changed with the machine data
MD 20110: RESET_MODE_MASK (definition of the control initial setting
after power up and reset) and
MD 20112: START_MODE_MASK (definition of the control initial setting
after part program start).
Table 6-25 Change system setting with MD
State Variable with MD
Power up (POWER ON) RESET_MODE_MASK
RESET/part program end RESET_MODE_MASK
Part program start START_MODE_MASK and
RESET_MODE_MASK
Select the required system behavior.
S After power up (POWER ON)
MD 20110: RESET_MODE_MASK, bit 0 = 0 or 1
Power up
(POWER ON)
