4 Overview of the process images
Variants
The microScan3 - PROFINET supports 8 PROFIsafe process images (in the controller:
modules ). The 8 process images can be divided into 2 groups depending on the PROFI‐
safe version (2.4 or 2.6.1). Which process images to use depends on the version of
PROFIsafe that the controller supports. If you do not know which PROFIsafe version your
controller supports, use the process images for PROFIsafe version 2.4.

The process images differ with regard to their size (6 bytes or 12 bytes) and the
incorporation of the iParCRC parameter.
6-byte process images must be used in the following cases:
• Only a limited range of peripheral addresses are available in your application.
• The microScan3 PROFINET is replacing a safety laser scanner of type S3000
PROFINET.
• The safety software for your S7 does not support 12-byte process images.
If your application requires constant monitoring of the checksums of the sensor config‐
uration, use a process image with iParCRC.
