Detailed Description
2.1 NC/PLC interface signals
Various NC/PLC Interface Signals and Functions (A2)
Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2-7
DB19, DBB24 (control of V24 interface) (HMI Embedded only)
Status byte for current status of data transfer for "RS-232 ON", "RS-232 OFF", "RS-232
EXTERNAL", "RS-232 STOP", etc., or if an error occurred during data transfer.
DB19, DBB25 (control of V24 interface) (HMI Embedded only)
Output byte for RS-232 data transmission error values.
DB19, DBB26 (control of file transfer via hard disk) (HMI Advanced only)
Status byte for current status of data transfer for "select", "load" or "unload", or if an error
occurred during data transmission.
DB19, DBB27 (control of file transfer via hard disk) (HMI Advanced only)
Output byte for error values for data transfer via hard disk.
2.1.6 Signals to channel
DB21, ... DBX6.2 (delete distance-to-go)
The rising edge on the interface signal generates a stop on the programmed path in the
corresponding NC channel with the currently active path acceleration. The path distance-to-
go is then deleted and the block change to the next part-program block is enabled.
2.1.7 Signals to axis/spindle
DB31, ... DBX1.0 (drive-test travel enable)
If machine axes are traversed by special test functions such as "function generator", an
explicit drive-test-specific enable is required for the movement:
DB31, ... DBX61.0 = 1 (drive-test travel request).
The movement is executed as soon as the travel enable is sent:
DB31, ... DBX1.0 = 1 (drive-test travel enable).
Notice
It is the sole responsibility of the machine manufacturer/system startup engineer to take
suitable action/carry out appropriate tests to ensure that the machine axis can be traversed
during the drive test without putting personnel or machinery at risk.
