Example of a call for FB (call in the OB100)
CALL "RUN_UP", "gp_par" (
Example: Override switchover
// Auxiliary flags used M100.0, M100.1, M100.2, M100.3
//Edge positive of MCP1Ready must check the override
//and measures for activation
// Initiate MCP block
//This example applies to the feedrate override;
//The interface and input bytes must be exchanged for spindle override.
