1) When using digital I/O modules with PCD3.E16x or A46x with 16 I/Os each
2) The address 255 is reserved for the watchdog on all PCD3. The I/O reserved for the watchdog can not be used
by the user, and analog and H modules must not be deployed with the slots with base address 240
3) Typical values, the processing time depends on the load on the communication interfaces
4) From HW version D and the matching FW, see detailed explanation in chapter 3.19
5) The specified duration is a buffer time, it depends on the ambient temperature (a higher temperature means
a shorter buffer time)
6) The 1kHz apply to a pulse/pause ratio of 1:1 and refer to the sum of the frequencies of the two inputs
7) The USB port is of type USB 1.1 Slave Device 12 MBit/s and can only be used for programming and in
combination with certain software products (Web-Connect, ViSi-PLUS with S-Driver) as S-Bus slave.
The download works twice as fast with a USB 2.0 hub.
Can also be used as serial data interface e.g. used for connecting a terminal, however, this makes the
commissioning and debugging with the debugger difficult.
