9.6 Bootloader option for the ADwin Ethernet interface
The option "bootloader" of the ADwin Ethernet interface offers the following
functions:
Functions– Automatical booting of the connected ADwin system
– Transfer of up to 10 processes to the ADwin system
– Start of the process 10 (if programmed)
You can reprogram the bootloader during operation and deactivate it by DIL
switch or software.
Programming with
ADethflash
You reprogram the bootloader by using the program ADethflash. The operating
system of the ADwin system (<ADwin9.BTL>) and up to 10 processes can be
programmed into the bootloader.
Reprogramming can be made in the normal operating mode of the ADwin Eth-
ernet interface. The reprogramming is only effective at the next power-up of
theADwin Ethernet interface.
For further information, please see the notes in the program ADethflash (in the
Windows start menu Programme ADwin).
Booting the ADwin
system
Program the bootloader and the operating system <ADwin9.BTL> of the
ADwin system. Activate the bootloader option by using the DIL switch no. 2
(see chapter 9.2.2). At the next power-up the following steps are executed:
–The ADwin Ethernet interface starts operating, the existence of the boot
file <ADwin9.BTL> is checked. Then the connected ADwin system is
booted and the possibly programmed processes (max. 10) are trans-
ferred to the ADwin system.
– If process 10 is available it will be started by the bootloader. If other pro-
cesses are also to be started, you have to insert the starting instructions
into the program code of process 10.
– Afterwards the ADwin Ethernet interface operates in the normal commu-
nication mode.
If no operating system of the ADwin system <ADwin9.BTL> is programmed
in the program ADethflash, it is the same as deactivating the bootloader. In this
case no processes are loaded and started.
Deactivating the
bootloader
Deactivating the bootloader is either made by using the DIL switch (see
chapter 9.2.2: Switch "Bootloader is not active" (ENET-1 only)) or by software.
In the latter case the bootloader is programmed without operating system
(ADwin9.BTL/ADwin10.BTL).
