FN 19: PLC – Transfer values to the PLC
Danger of collision!
Changes to the PLC can result in undesired behavior and
serious errors (e.g., inoperability of the control). For this reason,
access to the PLC is protected by password. The FN function
provides HEIDENHAIN as well as your machine tool builder and
suppliers the ability to communicate with the PLC from an NC
program. It is not recommended that the machine operator or
NC programmer use this. There is risk of collision during the
execution of the function and during the subsequent processing!
Only use the function in consultation with HEIDENHAIN, the
machine tool builder, or the supplier.
Comply with the documentation from HEIDENHAIN, the
machine tool builder, and suppliers.
The FN 19: PLC function transfers up to two numerical values or Q
parameters to the PLC.
