Bistable Function Blocks ¶ RS (FunctionBlock) SR (FunctionBlock)
RS (FB) ¶ FUNCTION_BLOCK RS Realizes a bistable reset-dominat latch (* Example declaration *) RSInst : RS ; (* Example in ST *) RSInst ( SET := VarBOOL1 , RESET1 := VarBOOL2 ); VarBOOL3 := RSInst.Q1 ; InOut: Scope Name Type Comment Input SET BOOL Rising edge: Set Q1 to TRUE RESET1 BOOL Rising edge: Reset Q1 to FALSE (dominant) Output Q1 BOOL Output value
SR (FB) ¶ FUNCTION_BLOCK SR Realizes a bistable set-dominat latch (* Example declaration *) SRInst : SR ; (* Example in ST *) SRInst ( SET1 := VarBOOL1 , RESET := VarBOOL2 ); VarBOOL3 := SRInst.Q1 ; InOut: Scope Name Type Comment Input SET1 BOOL Rising edge: Set Q1 to TRUE (dominant) RESET BOOL Rising edge: Reset Q1 to FALSE Output Q1 BOOL Output value
Counter ¶ CTD (FunctionBlock) CTU (FunctionBlock) CTUD (FunctionBlock)
CTD (FB) ¶ FUNCTION_BLOCK CTD Decrements a given value (* Example declaration *) CTDInst : CTD ; (* Example in ST *) CTDInst ( CD := VarBOOL1 , LOAD := VarBOOL2 , PV := VarWORD1 ); VarBOOL3 := CTDInst.Q ; VarWORD2 := CTDInst.CV ; InOut: Scope Name Type Comment Input CD BOOL Rising edge: Decrementing CV by one LOAD BOOL TRUE : Set CV to the start value PV PV WORD Start value for decrementing Output Q BOOL TRUE if CV = 0 CV WORD Current counter value
CTU (FB) ¶ FUNCTION_BLOCK CTU Increments a given value (* Example declaration *) CTUInst : CTU ; (* Example in ST *) CTUInst ( CU := VarBOOL1 , RESET := VarBOOL2 , PV := VarWORD1 ); VarBOOL3 := CTUInst.Q ; VarWORD2 := CTUInst.CV ; InOut: Scope Name Type Comment Input CU BOOL Rising edge: Incrementing CV by one RESET BOOL TRUE : Reset CV to 0 PV WORD Upper limit for incrementing Output Q BOOL TRUE if CV >= PV CV WORD Current counter value
CTUD (FB) ¶ FUNCTION_BLOCK CTUD Increments and decrements a given value Note Datatype WORD , which is used for PV in CODESYS, does not match the IEC standard, which for PV defines datatype INT . (* Example declaration *) CTUDInst : CUTD ; (* Example in ST *) CTUDInst ( CU := VarBOOL1 , CD := VarBOOL2 , RESET := VarBOOL3 , LOAD := VarBOOL4 , PV := VarWORD1 ); VarBOOL5 := CTUDInst.QU ; VarBOOL6 := CTUDInst.QD ; VarWORD2 := CTUDInst.CV ; InOut: Scope Name Type Comment Input CU BOOL Rising edge: Incrementing CV by one CD BOOL Rising edge: Decrementing CV by one RESET BOOL TRUE : Reset CV to 0 LOAD BOOL TRUE : Set CV to the start value PV PV WORD Start value for decrementing / upper limit for incrementing Output QU BOOL TRUE if CV >= PV QD BOOL TRUE if CV = 0 CV WORD Current counter value
