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)
