4 Functions of the Operator Module
This chapter describes the operation of the PLC via the operator
module. An example of commissioning operations is used to
explain the individual functions.
Initial PLC startup
When the power supply is switched on, the UPS device closes the
Power Fail circuit. The PLC operating system is started and the
”Waiting for Signal” message appears on the display of the oper-
ator module. The STOP, RUN and SF (SF = Central error) LEDs of
the operator module are not lit. The STOP LED lights up and the SF
LED light up after a few seconds.
If there is no program in the PLC, and the operating mode selector
switch (OMS) is set to STOP, the display will show the following
information after a few seconds:
The STOP and SF LEDs are lit. When the SF LED is lit, this indicates
that the PLC did not find a bootable program during the startup.
The ! in the display indicates that the PLC is in STOP status.
Clear the messages first of all:
X Choose menu item MAIN MENU r DIAGNOSTICS r CLEAR.
This will display the CLEAR menu.
X Instead of No select Yes by turning the MSS.
X Press the MSS.
X Press the MSS once more after ENTER is displayed.
The SF LED will go out and the exclamation mark will be cleared.
X Return to the basic menu.
You can now load a program into the PLC using XSoft or select the
main menu using the menu selector switch.
X Press the MSS when the cursor flashes in front of the MAIN
MENU menu item.
Your are now in the main menu and can select the individual menu
items.
Loading the program into the PLC
You can transfer a compiled program such as the program
TESTPRO from the PC to the PLC.
Requirement: The OMS must be set to STOP or RUN-P.
X Choose Online r Login in the XSoft programming software.
If there is no program in the PLC, the following window will
appear:
X Click on Yes.
This will confirm the storing of a bootable version of the program
in the working memory. The display will change:
If there is a program in the working memory already, it will be
overwritten after the confirmation.
X Click on Yes. The program name will change in the display.
Create a bootable version of this program:
X Click on Create Boot Project in the Online menu when you have
logged into the PLC.
The program is loaded into the program memory switched to
bootable status and is activated automatically. This is what is
required to start the program after the power supply is switched
on.
