In this case however, the 32-bit runtime metersoperate in the same way as 16-bit meters (Range of values: 0 to 32767 hours). The par-tial list extract with SSL ID W#16#0132 and index W#16#0008 displays the 32-bit runtimemeters 0 to 7 in 16-bit mode. This means that you can continue to use programs devel-oped for a CPU with 16-bit runtime meters that use partial list extract with SSL IDW#16#0132 and index W#16#0008.Error code Description0000h The job was executed without errors.8080h Wrong runtime meter number8081h A negative value was passed to parameter PV.8082h Overflow of the runtime meter.8091h Illegal value in input parameter MODE.8xyyh General error informationÄ Chap. 4.2 ‘General and Specific Error Information RET_VAL’ page 6614.1.58 SFC 102 - RD_DPARA - Reading Predefined ParametersWith SFC 102 RD_DPARA you can read the record set with the number RECNUM of aselected module from system data configured with STEP7. The read record set is enteredinto the target area opened with the parameter RECORD.The SFC 102 RD_DPARA operates asynchronously, that is, processing covers multipleSFC calls.Start the job by calling SFC 102 with REQ = 1. The job status is displayed via the outputparameters RET_VAL and BUSY.
