8.3 PROFIsafe/PROFINET system variables
PROFINET provides extremely detailed diagnostic information for each device down to
channel level.
Diagnostic states are important for system operation. If error messages occur, the process
has to be stopped in case of doubt. For this purpose, controllers from Phoenix Contact pro-
vide the following status information for the PROFINET network.
8.3.1 System variables of the iSPNS 3000
The SPNS system variable uses the SPNSV2_TYPE structure to provide the following infor-
mation about the iSPNS 3000.
Table 8-1 SPNS system variable and elements of the SPNSV2_TYPE structure
System variable/elements Type Meaning
SPNS SPNSV2_TYPE The SNPS system variable provides the information in the
SPNSV2_TYPE structure.
PRJ
NAME STRING PLCnext Engineer project name.
CRC DWORD Project CRC (32 bits) of the iSPNS 3000 boot project.
EXEC_TIME UDINT Runtime of the iSPNS 3000 program cycle in µs.
HAS_PRJ BOOL The safety-related application program and the program sources
are available in the memory of the iSPNS 3000.
DIAG
STATUS_REG WORD Diagnostic status register of the iSPNS 3000
The diagnostic status register of the iSPNS 3000 contains the
status information of the iSPNS 3000. It mirrors the state of the
iSPNS 3000 at all times including any error states that have
occurred on the iSPNS 3000. Additional information and error
parameters, in particular in the failure state (FS), are included in
the relevant diagnostic parameter registers of the iSPNS 3000
(elements SPNS.DIAG.PARAM_REG and
SPNS.DIAG.PARAM_2).
The information in the diagnostic status register is detailed in
Table 8-2 on page 178 .
PARAM_REG WORD Diagnostic parameter register 1 of the iSPNS 3000 (error code).
PARAM_2_REG WORD Diagnostic parameter register 2 of the iSPNS 3000 (additional
error messages for service/support).
EXT_PARAM_REG DWORD Extended diagnostic parameter register of the iSPNS 3000 (addi-
tional error messages for service/support).
CH2_PARAM_REG WORD Diagnostic parameter register 1 of the iSPNS 3000 channel 2
(CH2) (error code).
CH2_PARAM_2_REG WORD Diagnostic parameter register 2 of the iSPNS 3000 channel 2
(CH2) (additional error messages for service/support).
