Value Description80A0h Negative acknowledgment when reading from the module(module was removed during the transfer or module failed).80A2h DP protocol fault in layer 2, possible hardware-/ interface fault in the DP slave.80A3h DP protocol fault for user Interface/user.80A4h Communication failure(this fault occurs between the CPU and the external DP interface).80B0h SFC not valid for the type of module.Module does not recognize the record.Record number ≥ 241 not permitted.80B1h The length specified in parameter RECORD is wrong.80B2h The slot that was configured has not been populated.80B3h The actual type of module is not equal to the required type of module in SDB180C0h The module has registered the record but this does not contain any read data as yet.80C1h The module has not yet completed processing of the data of the preceding write operation for the samerecord.80C2h The module is currently processing the maximum number of jobs for a CPU.80C3h Required resources (memory, etc.) are currently occupied.80C4h Communication error.80C5h Decentralized periphery not available.80C6h The transfer of records was aborted due to a priority class abort.A general error 8745h only indicates that access to at least one byte ofI/O memory containing the record was disabled. However, the data wasread successfully from the module and saved to the I/O memory block.14.1.48 SFC 64 - TIME_TCK - Read system time tickThe SFC 64 TIME_TCK (time tick) retrieves the system time tick from the CPU. This mabe used to assess the time that certain processes require calculating the differencebetween the values returned by two SFC 64 calls. The system time is a "time counter"that counts from 0 to a max. of 2147483647ms and that restarts from 0 when an overflowoccurs. The timing intervals and the accuracy of the system time depend on the CPU.Only the operating modes of the CPU influence the system time.System time and operating modesOperating mode System time ...Restart RUN ... permanently updated.STOP ... stopped to retain the last value.Reboot ... is deleted and starts from "0".DescriptionVIPA SPEED7Integrated StandardSystem Functions > SFC 64 - TIME_TCK - Read system time tickHB00 | OPL_SP7 | Operation list | en | 18-30702
