14.1.43 SFC 55 - WR_PARM - Write dynamic parameterThe SFC 55 WR_PARM (write parameter) transfers the record RECORD to the targetmodule. Any parameters for this module that exist in the respective SDB will not bereplaced by the parameters that are being transferred to the module.These SFC can be used for digital-, analog modules, FMs, CPs and via PROFIBUS DP-V1.It is important that the record that must be transferred is not static, i.e.:n do not use record 0 since this record is static for the entire system.n if the record appears in SDBs 100 ... 129 then the static-bit must not be set.ParametersParameter Declaration Data type Memory block DescriptionREQ INPUT BOOL I, Q, M, D, L,constantREQ = 1: write requestIOID INPUT BYTE I, Q, M, D, L,constantIdentifier for the address space:54h = peripheral input (PI)55h = peripheral output (PQ)For hybrid modules the SFC returns the areaidentifier of the lower address. When theaddresses are equal the SFC returns identifier54h.LADDR INPUT WORD I, Q, M, D, L,constantLogical base address of the module. For hybridmodules the lower of the two addresses must bespecified.RECNUM INPUT BYTE I, Q, M, D, L,constantRecord number(valid values: 0 ... 240)RECORD INPUT ANY I, Q, M, D, L RecordRET_VAL OUTPUT INT I, Q, M, D, L The return value contains an error code if anerror is detected when the function is being pro-cessed.BUSY OUTPUT BOOL I, Q, M, D, L BUSY = 1: the write operation has not been com-pleted.With the first call to the SFC the data that must be transferred is read from the parameterRECORD. However, if the transfer of the record should require more than one call dura-tion, the contents of the parameter RECORD is no longer valid for subsequent calls to theSFC (of the same job).Two distinct cases exist for RET_VAL = 8xxxh:DescriptionConditionsRECORDRET_VAL (Return value)VIPA SPEED7Integrated StandardSystem Functions > SFC 55 - WR_PARM - Write dynamic parameterHB00 | OPL_SP7 | Operation list | en | 18-30692
