Stop Mode - Siemens Simantic ET200SP System Manual

Commissioning
10.6 Operating modes of the CPU
Example for the "Comparison preset to actual configuration" parameter
"Startup CPU only if compatible":
The input module DI 16x24VDC ST with 16 digital inputs is a compatible replacement for the
input module DI 8x24VDC ST with 8 digital inputs, because the pin assignment and all the
electrical and functional properties match.
"Startup CPU even if mismatch":
Instead of a configured digital input module, you insert an analog output module or no
module is present in this slot and thus in all subsequent slots. Although the configured inputs
cannot be accessed, the CPU starts up.
Note that the user program cannot function correctly in this case and take the appropriate
measures.
10.6.2

STOP mode

Function
The CPU does not execute the user program in STOP mode.
All outputs are disabled or react according to the parameter settings for the particular I/O
module: They provide a substitute value as set in the parameters or retain the last value
output keeping the controlled process in a safe operating status.
In STOP mode, the motor starter responds according to how it was parameterized for the
CPU STOP state. The CPU STOP state can be circumvented with the manual local control
(Local Control) function. If the CPU is switched off, a motor can be switched on in the motor
starter's commissioning mode.
