FUNCTION_BLOCK PSENvipCom
VAR_INPUT
bStartToolChangeE0 : SAFEBOOL; // Start signal for the communication from
PSENvip
bValidToolChangeE1 : SAFEBOOL; // Tool value from PSENvip is valid
bToolTypeE2 : SAFEBOOL; // Tool value Bit 0 from PSENvip
bToolTypeE3 : SAFEBOOL; // Tool value Bit 1 from PSENvip
uiToolTypeCNC : SAFEUINT; // Tool value from the CNC
END_VAR
VAR_OUTPUT
bAcknowledgeToolChangeA0 : SAFEBOOL; // Acknowledge signal for the communication
from PSS4000
bAcknowledgeToolTypeA1 : SAFEBOOL; // Tool value Bit 0 from PSS4000
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
bStartCom : BOOL; // Start communication
bToolValid : BOOL; // Tool from PSENvip is valid
uiToolTypePSENvip : SAFEUINT; // Tool type from PSENvip
END_VAR
// Communication between PSENvip and PSS4000
