The following characteristics of the MAC and IP address handling should be

considered in order to avoid network problems while reusing previously used CPU

modules within the same plant:

• The stored swap addresses will be remembered until erased by an IP-config

session (Restore factory settings) or until started up as a backup CPU in new

context (in this case a new swap will take place).

• A CPU running in standalone mode (with RCU terminator fitted) will always

use its own native addresses.

AC 800M High Integrity

AC 800M can easily be configured for usage in safety critical applications. The

main components of such a system are

• PM865 with SM810/SM811 or

• PM867 with SM812,

• SS823 and

• S800 I/O High Integrity, running a High Integrity version of Control Software.

The PM865/PM867 processor unit has increased internal diagnostics, compared to

PM864. The added functionality on PM865/PM867 includes:

• Double over voltage protection on internal voltages

• A additional watchdog timer updated with data from SM810/SM811 or SM812

respectively.

• Increased oscillator supervision

• Support for S800 I/O High Integrity

• Support for SM810/SM811 or SM812 respectively.

• Increased system diagnostic and online self tests.
