System variables and status information > System variables
System variable Type - description
CH2_EXT_PARAM_REG DWORD - Extended diagnostic parameter register of the safety
CPU channel 2 (CH2) (additional error messages for service/sup-
port).
INFO
CYCLE_TIME UDINT - Safety CPU cycle in μs.
TEMP
TEMP_CURRENT INT - Current measured temperature of the safety CPU.
TEMP_MIN INT - Minimum measured temperature of the safety CPU since the
last PowerON of the device.
TEMP_MAX INT - Maximum measured temperature of the safety CPU since the
last PowerON of the device.
STATUS_REG WORD - Safety CPU temperature status register.
■ 0x0000:
TThe temperature of the safety CPU is in uncritical range.
■ 0x0080:
The temperature of the safety CPU is close to the tolerance limit
in the critical range. The CPU remains in the RUN state and
returns a warning with the error code 0xF
A41.
■ 0x8000:
The temperature of the safety CPU is exceeding the permissible
range. The safety CPU switches to the safety state and returns
an error with the error code 0x924D.
CPU
LOAD_CURRENT INT - Current CPU load of the safety CPU.
LOAD_MIN INT - Minimum CPU load of the safety CPU since the last Pow-
erON of the device.
LOAD_MAX INT - Maximum CPU load of the safety CPU since the last Pow-
erON of the device.
STATUS_REG WORD - CPU status register of the safety CPU.
FW_VERSION
VERSION_MAJOR BYTE - Main version of the safety CPU firmware (major version).
VERSION_MINOR BYTE - Side version of the safety CPU firmware (minor version).
VERSION_BUILD WORD - Build number of the safety CPU firmware.
FPGA_VERSION
VERSION_MAJOR BYTE - Major version of the Safety CPU hardware FPGA (major
version).
VERSION_MINOR BYTE - Side version of the safety CPU hardware FPGA (minor
version).
VERSION_BUILD WORD - Build number of the safety CPU hardware FPGA.
FW_UPDATE_STATUS UINT - Status of the safety firmware update.
SOFT_RESET_REG WORD - Software reset register of the safety CPU.
