System variable SPLC
System variable Type - description
PND_S1_INPUTS PND_IO_512 - input process data
■
Memory area for input process data that the PROFINET device
receives from the higher-level PROFINET controller.
PND_IO_DRIVEN_BYPLC INT - Applicative system redundancy
■
Number of the PROFINET controller currently connected to the
PROFINET device.
■
Indication from which higher-level PROFINET controller the data
in the PROFINET device come from.
–
0: No PROFINET controller
–
1: PROFINET controller A
–
2: PROFINET controller B
5.15.3 System variables
■
The system variable SPLC is a system variable organized as a data structure.
■
The SPLC system variable provides the following information about the safety CPU
using the SPNSV2_TYPE data structure.
System variable Type - description
SPLC SPNSV2_TYPE - Data structure
PRJ
Name STRING - Name of the iCube Engineer project.
CRC DWORD - Project CRC (32-bit) of the safety CPU boot project.
EXEC_TIME UDINT - Runtime of the safety CPU programme cycle in μs.
HAS_PRJ BOOL - Set if safety-related application program and program
sources exist in the memory of the safety CPU.
DIAG
STATUS_REG WORD - Diagnostic status register of the safety CPU.
■
Contains the status information of the safety CPU. It reflects the
status of the safety CPU including any error states of the safety
CPU that may have occurred at any time.
■
Additional information and error parameters, espe-
cially in the fail safe, are contained in the
associated diagnostic parameter registers of the
safety CPU (elements SPNS.DIAG.PARAM_REG and
SPNS.DIAG.PARAM_2_REG).
