Siemens SIMATIC S5 Operating Instructions

Forcing (only possible with S5-130 AIK)
Call function selection menu
with
m
Select PU-function
Nomenclature in menu FORCE ON-OFF
This function
is only possible in operating
mode 21 "PC WITH PC-MEM
" (only with
PC S5-130
A/K) or 22 "PC WITH PU-MEM".
Put switch on CPU to "STOP" positon.
Example: RQ 3.1
The current signal status is displayed.
Notes:
With the function "forcing", outputs
(Q),
flws (F) and timers (T) may be switched to
I
a desired signal status.
When forcing-outputs or flags, depending
on the type of operation
progrannned
(e.g. = ), the following reaction is
obtained:
Operation
"=": As long as key is
pressed, the selected output or flag will
carry "1" signal; When releasing the key,
"0" signal.
Operation "S": When pressing key
,
the selected output or flaq will carry "1"
-
.
signal, which is self-holding.
Important! Forced outputs or flags must be
reset to "0" signal.
Operation
"R": When pressing key ,
the selected output or flag is reset to
"0" signal.
Operation "SET": After pressing key
,
the preset time value of the selected
timer expires.
Forcing of timers with SET
is only
possible once. To repeat the operation
an initializing pulse must first be
given on the CPU.
Operation "RT": After pressing key
,
the selected timer is stopped and
reset, provided
it was started with
SET and has not expired.
When the function forcing
is ended with
',
\. i
key , an initializing pulse is
activated by the CPU.
