Inserting a program (jog of path)
Requirement
Often, users have a requirement to interrupt program execution in response to an event, e.g. of the PLC, to insert any chosen movement and then to continue to interrupted program.
Insertion of any chosen movement can be implemented through a second "auxiliary channel", which is connected to the same physical axes as the first channel. To this end, a further logical axis is assigned to identical physical axes.
Switching over
Exclusive access to the physical axes through the channels is controlled by one control bit of each channel on the PLC interface
Position shift
Movement can be continued with axes that have been shifted by the inserted program. If this is not desired, the inserted program must return the axes to the position at the time when the program was started.
Licences
A pure auxiliary channel (all axes linked) does not need any additional license.
Interfaces
The following interfaces are available:
- Axis configuration via the axis parameter list
- Switching over the channel through HLI by PLC
- Display of the logical/physical axis configuration on HLI
- Display of the axis offsets (physical <-> logical) on HLI
