A.2.2
Application example
Shift the control logic into the converter
It is only permissible that a conveyor system starts when two signals are present simultaneously.
These could be the following signals, for example:
• The oil pump is running (the required pressure level is not reached, however, until after 5
seconds)
• The protective door is closed
To implement this task, you must insert free function blocks between digital input 0 and the
command to switch on the motor (ON/OFF1).

Signal interconnection for control logic
The signal of digital input 0 (DI 0) is fed through a time block (PDE 0) and is interconnected with
the input of a logic block (AND 0). The signal of digital input 1 (DI 1) is interconnected to the
second input of the logic block. The logic block output issues the ON/OFF1 command to switch-
on the motor.
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
Interconnecting the time block to the 1st AND input
p20030[1] = 722.1
Interconnecting the status of DI 1 to the 2nd AND input
r0722.1 = Parameter that displays the status of digital input 1.
p0840 = 20031
Interconnect the AND output to ON/OFF1
