Button Description
RESET If pressed during power-on: Enter serial download of firmware. This is
signalized by blinking of the RUN LED with a frequency of 1 Hz. If
pressed during normal operation: reserved for future implementation.
Fn If pressed during power-on: Bootproject will not be loaded. This is sig-
nalized by blinking of the RUN LED with a frequency of 1 Hz. If pressed
during normal operation: reserved for future implementation.
RUN/STOP Switches the processor module from RUN to STOP mode.
The AC500 processor module can display various errors according to the error classes. The
reaction of the Processor Module is different for each type of error. See System Technology
LED display .
1.2.2.2.6 Technical Data
The System Data of AC500 and S500 Ä Chapter 2.6.1 “System Data AC500” on page 1248 are
valid for standard version.
The System Data of AC500-XC Ä Chapter 2.7.1 “System Data AC500-XC” on page 1309 are
