7.8 Safety Variables and Monitoring
The drive provides a list of variables for monitoring the safety states. All variables can be accessed via UPIDs and are
shown in LinMot-Talk under \Variables\
7.8.1 Safety Variables on Safety Module

Software Type 0302h
Enum16
0001h Software Type
The installed firmware on the safety module is PROFIsafe. This firmware
supports the PROFIsafe interface and the safety functions over the safe digital
I/Os.
Software
Version
0301h
UInt16
-
Software Version
This parameter displays the software version installed on the safety module.
The software version consists of two bytes which stand for the major and
minor version.
High Byte: major version
Low Byte: minor version
Software CRC
MCU1
0303h
UInt32
-
MCU 1 CRC
This value shows the CRC over the MCU1 firmware.
Software CRC
MCU2
0304h
UInt32
-
MCU 2 CRC
This value shows the CRC over the MCU2 firmware.
Parameter
CRC
0305h
UInt32
-
Parameter CRC
This value shows the CRC over the values of the safety parameters.
This CRC must be used when the configuration is loaded from the flash card.
Safe Address
0306h
UInt16
-
Safe Address
This value shows the position of the safe address switches S11/S12 read at
startup in the low byte. In the high byte the fixed value of CDh is set.
