WAGO-I/O-SYSTEM 750 Appendix 151750-666/000-003 4FDI/2FDO 24V/10A PROFIsafe V2 iParManualVersion 1.2.0, valid from HW/SW Version 01/01Table 45: PROFIsafe F parametersF Parameters Default value DescriptionF_iPar_CRC 32608 The F_iPar_CRC is only available whenF_Block_ID = 1 and specifies a comparisonvalue for the CRC value via the iParameter(iPar_CRC). The PROFIsafe data exchangeonly starts when the values for F_iPar_CRCand der iPar_CRC match. If they differ, thePROFIsafe I/O module makes a restore requestof the iParameter from the iPar server.The F_iPar_CRC value 0 holds specialstanding. This value switches the PROFIbusI/O module into test mode.The CRC value (iPar CRC) is displayed by theWAGO parameterization tool and must betransferred with the configuration tool of thesafe PLC to the F parameter of the PROFIsafeI/O/ module.
