1.2 NC/PLC interface signals
DB19 DBX 0.3 / 0.4 (Delete cancel alarms / Delete recall alarms) (HMI Advanced)
Request to delete all currently pending alarms with Cancel or Recall delete criterion. Deletion of the alarms is
acknowledged via the following interface signals.
• DB19 DBX20.3 (Cancel alarm deleted)
• DB19 DBX20.4 (recall alarm deleted)
DB19 DBX0.7 (Actual value in WCS, 0=MCS)
Switching over of actual-value display between machine and workpiece coordinate system:
• DB19 DBX0.7 = 0: Machine coordinate system (MCS)
• DB19 DBX0.7 = 1: Workpiece coordinate system (WCS)
DB19 DBB13 (control of the file transfer via hard disk) (HMI advanced only)
Job byte to control file transfer via hard disk. The jobs relate to the user control file in the interface signals:
DB19 DBB16 (parts program handling: Number of the control file for user file names)
DB19 DBB17 (parts program handling: Index of the file to be transmitted from the user list)
DB19 DBB16 (control of file transfer via hard disk) (HMI Advanced only)
Control byte for file transfer via hard disk to define the index for the control file (job list). This file is handled
according to the job in the interface signal:
DB19 DBB13
DB19 DBB17 (part program handling: Index of the file to be transferred from the user list)
Control byte for file transfer via hard disk to indicate the line in the user control file in which the control file to be
transferred is stored
DB19 DBB26 (part program handling: status)
Status byte for current status of data transfer for "select", "load" or "unload", or if an error occurred during data
