bStartToolChangeE0 : SAFEBOOL; // Start signal for the communication from

PSENvip

bValidToolChangeE1 : SAFEBOOL; // Tool value from PSENvip is valid

bAcknowledgeToolTypeA2 : SAFEBOOL; // Tool value Bit 1 from PSS4000

END_VAR

VAR

RisingFlagE0 : R_TRIG; // FUNCTION block rising edge for Signal E0

RisingFlagE1 : R_TRIG; // FUNCTION block rising edge for Signal E1

bComEnd : BOOL; // End of communication

bToolchangeFlag : BOOL; // Rising edge for start of the communication

bToolValidFlag : BOOL; // Rising edge for valid tool from PSENvip
