6.6.1 FB 402 MC_Reset - Error acknowledgement
Valid for firmware version V3.1.x of the integrated technology
Purpose
• Use the technology function "MC_Reset" to acknowledge all errors accepting
acknowledgment in the user program. Acknowledgment of fatal errors is only
possible either by cycling power, or by downloading the project data to the
module again. The acknowledgment also clears the entries at the ErrorID and
ErrorBuffer parameters, and resets the ErrorStatus bits in the technology DB.
• Use the technology function "MC_Reset" Restart = TRUE to start the re-
initialization (restart) of axes, cams, cam disks, external encoders and
measuring sensors. After initialization, the status of an axis with incremental
encoder is "Not homed." The cam originally configured in S7T Config is
restored at the cam disks.
• When executing the "MC_Reset" technology function at the MCDevice
technology DB (Axis = DB no. MCDevice DB), the maximum command
execution time is reset to "0" (MaxLoopDuration at the MCDevice DB.)
• The system continues command processing during a restart. However, the TO
performing the restart can not accept any commands for the duration of the
restart.
Applicable to
• Velocity axes
• Positioning axes
• Synchronization axes
• Output cam
• Measuring input
• Cam disks
