Starting up the PLC with a bootable and activated
program
After each startup, the activation of menu item LOAD or REBOOT,
the PLC will create an executable program from the activated
program which it will store in the working memory. This will over-
write any executable program that is present. The activated
program is retained.
If the OMS is set to RUN-P or RUN, the PLC runs a warm start: the
(POU) variables and the variables declared as PERSISTENT are
initialised.
Entering parameters or status modifications
Any changes to PLC parameters or states such as Start/Stop you
wish to make can be password protected. To do this proceed as
follows.
Without a password
The program is processed according to the position of the oper-
ating mode selector switch (OMS). If the OMS is set to RUN, the
program is processed and the display shows:
X Press the MSS to reach the main menu.
Setting the OMS to RUN-P, STOP or MRES will execute the function
accordingly.
With password
An assigned password will freeze the status of the PLC and the
parameters at the time the password was assigned. In this way,
the position of the OMS can also be frozen to a particular position,
such as RUN. In the event of a power failure, the RUN status will
be retained when power is restored. The display shows:
The program is processed and the RUN LED is lit.
You can only reach the main menu by entering the password:
X Turn the MSS so that the display shows PASSWORD.
Press the MSS so that the display shows:
If the position of the OMS was changed, a message will indicate
how the OMS should be set, such as Key: RUNP.
X Switch the OMS to this position to clear the message.
X Enter the password (a Section “Entering passwords” on
Page 39).
Entering an incorrect password will return you to the PASSWORD
menu.
h
If you have loaded the program but not a bootable version
of it, the program will be deleted on startup.
