flash ROM for the operating system and 256 KB of SRAM and 512 KB
of flash disk for your application and for storage. Furthermore, part of
the SRAM is backed up by a battery. This provides dependable
protection during power outages.
1.2.4 RS-232/485 communication ability
ADAM-5510/P31 has three serial communication ports. This gives
ADAM-5510 excellent ability to communicate with other devices, as
well as aiding the construction of networks in the field. Of these three
serial ports, COM1 is an RS-232 port while COM2 is an RS-485 port.
These two ports should satisfy the demand for communications
having different characteristics. COM3 is a programming port through
which you can download or transfer executable programs from the
host PC. (TX, RX, GND Supported, See Page 2-12)
1.2.5 Built-in real-time clock and watchdog timer
ADAM-5510/P31's microcontroller includes a real-time clock and a
watchdog timer. The real-time clock records events while they occur.
The watchdog timer is designed to automatically reset the micropro-
cessor if the system fails. This feature greatly reduces the level of
maintenance required and makes the ADAM-5510/P31 ideal for use in
applications which require a high level of system stability.
1.2.6 ADAM-5510/P31 Remote I/O Function
ADAM-5510/P31 Remote I/O Function offers more flexibility for your
ADAM series product applications. More I/O points are available for
use, and you can flexibly combine ADAM-4000 and ADAM-5000
products, according to your application, to meet your centralized/
distributed I/O points requirements. This feature reduces your efforts
in cabling layout and maintenance. Furthermore, you can take advan-
tage of the flexibility for future I/O points expansion.
