5.3.4 Pro II-Boot
With Pro II-Boot, you have a boot loader expansion, which can
– boot an
ADwin-Pro II
system.
– load up to 10 processes.
– start process 10 automatically (if present).
– save data.
Pro II-Boot is an ordering option for processor modules with Ethernet interface.
An upgrade is not possible.
Software
By installation of the
ADbasic
and the
ADwin
drivers from the CDROM, all files
/ programs necessary for the boot loader option have already been copied to
the hard disk.
If you use the boot loader, an application, which you have written with a pro-
gram for visualization of measurement data, must not reboot the
ADwin
system.
5.3.5 Module monitoring with Watchdog
You can monitor your processor module with a watchdog. The watchdog gene-
rates a reset, when a signal, generated by a program code, does unexpectedly
not arrive (see also "
ADwin-Pro
System Specifications - Programming in
ADbasic
").
The watchdog reset signal sets the digital and analog outputs at Pro modules
to those values, which correspond to the configuration after power-up, nor-
mally digital 0 or 0 Volt. Please note that Pro II modules will only react to the
watchdog signal if the T11 processor has revision E06 at least.
Programmig in ADbasic
The watchdog is comfortably programmed with
ADbasic
instructions. The
instructions are described in
ADbasic
online help and in the Pro II Software
manual.
The include file
ADwinPro_All.inc
contains the watchdog instructions:
Notes in relation to Pro II-Flash-Boot:
– Please pay attention to the fact that the watchdog has to be reset every
1.6s, since a longer time interval between two impulses will be inter-
preted as an error.
– The watchdog can also be used with the boot loader Pro-Flash-Boot, but
does not automatically load and start the software.
– Test your programs always with the watchdog switched off. Activate it
only when your programs work properly!
