Setting the control logic
Parameter
Description
p20161 = 5 The time block is enabled by assigning to runtime group 5 (time slice of
128 ms)
p20162 = 430 Run sequence of the time block within runtime group 5 (processing before
the AND logic block)
p20032 = 5 The AND logic block is enabled by assigning to runtime group 5 (time
slice of 128 ms)
p20033 = 440 Run sequence of the AND logic block within runtime group 5 (processing
after the time block)
p20159 = 5000.00
Setting the delay time [ms] of the time module: 5 seconds
p20158 = 722.0 Connect the status of DI 0 to the input of the time block
r0722.0 = Parameter that displays the status of digital input 0.
p20030[0] = 20160
Interconnect the timer block to the 1st input of the AND
p20030[1] = 722.1 Interconnect the status of DI 1 with the 2nd AND input
r0722.1 = Parameter that displays the status of digital input 1.
p0840 = 20031
Interconnect the AND output to ON/OFF1
Explanation of the example using the ON/OFF1 command
Parameter p0840[0] is the input of the "ON/OFF1" block of the inverter. Parameter r20031 is
the output of the AND block. To interconnect ON/OFF1 with the output of the AND block, set
p0840 = 20031.
