Interface and parameters of block search
Validity of block search parameters
The parameters of block search (block search mode, specification of restart position) are preselected before the NC program is started. When a program is started the actual settings are taken as program start parameters. Any change after a program has been started has no more effect on the actual running program.
Availability on the HMI-Interface
Because the setting of this parameters must be done just once before program start, it is not time critical. The parameters are available on the HMI-interface, which also could be accessed via PLC by ADS-Read/Write-Requests.
