The MAC addresses of the network interfaces of the PM595-4ETH are printed on the label in
the following way:
MAC ETH1
MAC ETH2
MAC ETH3
MAC ETH4
The figure below shows the assignment of the MAC addresses to the corresponding interface.
Fig. 6: Assignment of the MAC addresses to the corresponding interface
The figure above also shows the assigned SLOT-Numbers 1, 2, 5 and 6.
1.2.2.2.4 Storage Elements
AC500 processor modules are supplied without a lithium battery. It must therefore be ordered
separately. The TA541 lithium battery is used to save SRAM contents of processor modules
(PM595-4ETH-F only) and back up the real-time clock in case of power failures. Even if the pro-
cessor modules can work without a battery, its use is still recommended in order to prevent
process data being lost in case of power failures (PM595-4ETH-F only).
The processor module monitors the battery's state of charge. If the processor module signals a
low state of charge (via the diagnostic system and LED), the battery has to be replaced immedi-
ately.
For technical data, handling instructions and a description of the insertion/replacement of the
battery, please refer to the chapter TA541 Lithium Battery
Ä
Chapter 1.8.2.5 “TA541 - Lithium
Battery” on page 1153.
The processor module PM595-4ETH-M-XC is maintenance-free. The lithium
battery TA541 in this processor module type is used only for back-up of the real-
time clock (RTC) in case of no power supply. If the RTC is not used, there is no
need to install a TA541 lithium battery.
AC500 processor modules are supplied without memory card. It must be ordered separately.
