9.4 Messages when components are replaced after Safety Integrated has
been commissioned
Safety-relevant components are assigned a CRC checksum, which can be used to identify if
the hardware was changed:
● Replacing certain drive components after Safety Integrated has been commissioned.
● Different checksums as a result of series commissioning with Safety Integrated functionality
The appropriate messages are displayed, depending on the components involved and the
control type:
Control type Alarm
Extended Functions via PROFIsafe F01650 SI P1 (CU): Acceptance test required
Fault value 2005
Indicates that the Control Unit has been replaced.
A01695 SI Motion: Sensor Module has been replaced
Indicates that the Sensor Module has been replaced.
C30711 SI Motion P2: Defect in a monitoring channel
Fault value 1031
Stop response STOP F
As a consequence of A01695, a defect is signaled in a mon‐
itoring channel.
Basic procedure
WARNING
Unsafe states after a component has been replaced
Non-safe states are possible after a component has been replaced. If persons are in the
danger zone, accidents causing death or severe injury can occur.
● Before re-entering the hazardous area - and before resuming operation - perform a
simplified function test for the drive affected by the component replacement (see Chapter
"Acceptance test (Page 341)").
Use the following function in the SINUMERIK ONE Commissioning Tool to acknowledge a
CRC checksum that differs for one of the reasons listed above:
● Commissioning > Safety Integrated > Overview > Confirm SI hardware
Component replacement (software/hardware)
