2.4.3 Setting the operating mode of the ETCHx
The ETCHx can be operated in two operating modes:
ƒ Variant "Standalone" (delivery variant)
– Directly after the voltage has been applied, the control system loads
the firmware.
– The control system executes a fixed program.
ƒ Variant "with MMI"
– After the voltage has been applied, the control system waits until the
firmware is loaded by a PC via any MMI program (e.g. ETC−MMI).
– Variable user programs can be executed.
Standalone (delivery) With MMI
Use The control system operates a
machine without further
coupling to a PC. The control system operates a
machine with coupling to a
user interface, which is used
for loading programs and
operating the control system.
User program A fixed program runs in the
control system. Variable user programs can be
loaded into the control
system.

control system Boot loader

Installation of the firmware The firmware is loaded and
installed in the EEPROM by the
boot loader. The Loader is loaded and
installed in the EEPROM by the
boot loader.
Behaviour of the control
system after the voltage has
been applied After the voltage has been
applied, the control system
automatically starts with its
firmware. After the voltage has been
applied, the control system
waits until the firmware is
loaded via the PC.
LED display after the voltage
has been applied After the firmware has been
started successfully, the green
watchdog LED lights up. The successful start of the
loader is indicated by
circulating LEDs (1 ... 6).
Starting the firmware Before the start, the firmware
is loaded from the EEPROM of
the control system into the
RAM and started. The firmware is located on the
PC and is loaded into the RAM
of the control system and
started when the MMI user
interface is started.
After the firmware has been
started successfully, the green
watchdog LED lights up.
The "Standalone" operating mode is factory−set.

Note!
If the ETCHx has already been operated in the "with MMI"
operating mode and is to be reset to the "Standalone" operating
mode, the file "NetBoot.rsc" (loader) must be deleted in the
control system and the firmware file ETCHC_A.rsc (ETCHC) or
ETCPC.rsc (ETCPC) is to be transferred instead. For this purpose,
proceed as described in the following section; the files that are
to be exchanged are the only difference.
