The following table shows the reaction of the PLC when the oper-
ating mode selector switch is changed. Requirement: the power 
supply must be switched on.
Menu selector switch (MSS)
You can use the menu selector switch to select a function from the 
menu overview in the LCD display. The current setting is indicated 
by the cursor, a flashing arrow on the left of the display. The menu 
selector switch is a pushbutton that can also be rotated. Turn it to 
move the cursor up or down. When the cursor indicates the 
required function, press the knob in order to select the function 
concerned.
Battery
The battery is used to back up the clock module.
As the XC600 controller can only be used in conjunction with a 
UPS unit, the backup of retentive data is ensured. This is stored on 
the flash disk in the CPU. The time is stored in a battery backed 
RAM module.
LEDs
The current PLC status is indicated by the three LEDs.
CompactFlash card
The CompactFlash card is used for saving programs and recipes. 
You can use the operator module to copy these programs and 
recipes from the hard disk to the CompactFlash card. The content 
of the CompactFlash card can be shown on the display.
Only type I or II cards can be used. 
The CompactFlash card can only be fitted or removed when the 
power supply for the XC600 PLC is switched off! A handling error 
of this kind may cause a system crash or damage to the card.
XC-CPU601-E.M processor
The module is based on a Pentium PC (166 MHz) in compact ”PC/
104” format. It is fitted with a 64 MB flash disk memory that can 
store both the user program and the source code. 
Task
The CPU communicates via the Ethernet interface with the PC. 
A program download and other Online functions can be executed 
from the PC.
Several XC600 PLCs can be connected via Ethernet. For data 
exchange between PLCs in a network requiring no PLC related 
functions, the object directory can be used in addition to network 
variables. This is abbreviated to OD in the rest of this manual. 
Setup 
The module contains a board with the PC/104+ bus. The following 
interfaces are provided:
Change
Reaction
STOP r RUN-P
The user program is started and the (POU) 
variables are unchanged. All access func-
tions are available via the programming 
device.
RUN-P r RUN
The user program is processed. A debug-
ging or status change is not possible.
RUN-P r STOP
The user program is stopped.
STOP r MRES r STOP
The PLC remains in STOP status. The simple 
variables, POU variables and those assigned 
with RETAIN will be initialised.
h
Only change the back-up battery with the power supply 
switched on, otherwise the time data will be lost.
STOP
The user program is not running.
RUN
The user program is running.
SF
SF (=central error) flashes when the operating system is 
started; is permanently lit after startup, if the PLC does 
not have a bootable program.
h
The “.” in the type designation stands for the size of the 
user program memory. 1, 2, 4 and 8 MB memories are 
available)
