Technical data for communication ports and interfaces is described in Table 49 on
page 241.
Battery
The memory content is backed up with either an internal or external battery unit
(SB821). For back-up time see e Table 59 on page 257.
Weight • 1200 g (2.6 lb) (package PM864K01).
• 2800 g (6.1 lb) (package PM864K02).
Dimensions W 119 x H 186 x D 135 mm (4.7 x 7.3 x 5.3 in)
Width is measured along the DIN-rail, depth from the
wall, and height vertically, including lock
mechanism.
The figures in Table 59 on page 257 are valid if the batteries have been installed
after a normal CPU power-up, allowing for the memory back-up function to be
activated.

Performance Data
The PM864 processor unit, in single configuration, has performance data which
theoretically peaks at twice the performance compared to the PM860. The useful
sustained performance improvement is, however, a bit lower and somewhat
dependent on the actual application program but can be expected to be 10 to 50%
compared to PM860. In redundant configuration the execution performance is
somewhat lower than in single configuration.
Switch over time from Primary CPU to Backup CPU, in redundant configuration, is
less than 10 ms.
