The start–up switch PLC Stop can be activated either during operation or power–up.
The debug mode (see “Operation and Programming”, Chapter 7) causes the PLC to remain in
PLC Stop after the control system has powered up. All power–up modes that have been set
either via softkeys or via hardware start–up switches will only come into effect after the next
power–up of the control system. The hardware start–up switch “PLC STOP” (position 4) is
active immediately. The priority of the power–up modes activated via the softkeys on the ope-
rator panel is higher than that of the hardware start–up switches.
Example:
S
Hardware start–up switch position 3
S
Restart from operator panel
=> Restart is active from next power–up of the control system
The Run mode activates the cyclic mode.
