output terminal.
Inverter
operation
monitorin
g
<variable> =
<input terminal>
=
Fetches information from an inverter
input terminal.
delay on <variable 1> TD (k)
<variable 2/
constant>
Turns on the terminal specified by
<variable 1> after the time specified by
<variable2/constant> elapses.
Delay
operation
delay off <variable 1> TD (k)
<variable 2/
constant>
Turns off the terminal specified by
<variable 1> after the time specified by
<variable2/constant> elapses.
timer set TD (k)
<variable/
constant)
Sets <variable/constant> in a specified
timer and starts the timer.
Timer
control
timer off TD (k) Stops the specified timer.
<variable> = UB (ii)
Fetches internal user contact information
and stores it in <variable>. (0 = off, 1 =
on)
<variable> = UBw
