1 from 16 at 60Hz interference frequency6.4.5 Analog part - Parameterization13Byte of parameter data are available for the configuration. Parameters of the analogpart may be set by means of the AI5/AO2 submodule of the Siemens CPU during hard-ware configuration.By using the record set 1 of the SFC 55 "WR_PARM" you may alter the parameterizationin the module during runtime. The time needed until the new parameterization is valid canlast up to 2ms. During this time, the measuring value output is 7FFFFh.The following table shows the structure of the parameter data:Byte Bit 7 ...
