Note
An acknowledgement signal is required for starting the
machine:
• Prior to the first start (normal operation)
• After triggering emergency stop
• After opening the safety door in normal operation
• After error recognition during plausibility checks for the
speed value
Important hardware component settings
Below, several important settings from the hardware configuration
of STEP 7 are shown to provide you with an overview.
These settings are available in the included STEP 7 project. It
is basically possible to change these settings (e.g. due to individual
requirements), but please consider the following note:
376 Functional Example No. AS-FE-I-012-V10-EN
Attention
The settings shown below contribute to meet the requirements
of category 3 according to EN 954-1 and
SIL 2 of IEC 62061. Changes at the settings may cause
loss of the safety function.
If you implement changes (e.g. add an additional module),
the sample code has to be adapted accordingly.
