The following FBs perform reversible/irreversible operation and ON/OFF operation and operates as a timer and a counter.
■Motor Irreversible (2 Input/2 Output)
Function block symbol Processing details
M+M_NREV Performs irreversible operation and controls a solenoid valve.
■Motor Reversible (2 Input/3 Output)
Function block symbol Processing details
M+M_REV Performs reversible operation.
■ON/OFF Operation (2 Input/2 Output)
Function block symbol Processing details
M+M_MVAL1 Controls an ON/OFF motor valve and solenoid valve.
■ON/OFF Operation (2 Input/3 Output)
Function block symbol Processing details
M+M_MVAL2 Controls an ON/OFF motor valve (with intermediate status).
■Timer 1 (Timer stops when COMPLETE flag is ON)
Function block symbol Processing details
M+M_TIMER1 This function block is a clock timer. It stops counting the time when the timer count value reaches
the set value.
■Timer 2 (Timer continues when COMPLETE flag is ON)
Function block symbol Processing details
M+M_TIMER2 This function block is a clock timer. It continues to count the time even if the time count value
exceeds the set value, and the timer stops when the time count value reaches the timer high limit
value.
■Counter 1 (Counter stops when COMPLETE flag is ON)
Function block symbol Processing details
M+M_COUNTER1 This function block is a counter that counts contact signal inputs. It stops counting the inputs when
the count value reaches the set value.
■Counter 2 (Counter continues when COMPLETE flag is ON)
Function block symbol Processing details
M+M_COUNTER2 This function block is a counter that counts contact signal inputs. It continues to count the inputs
even if the count value exceeds the set value, and stops counting the input when the count value
reaches the counter high limit value.
■Push Button Operation (5 Input/5 Output)
Function block symbol Processing details
M+M_PB_ Performs push button operation.
