1) Using digital I/O modules PCD2.E16x or A46x with 16 I/Os each
2) On all PCD units, address 255 is reserved for the watchdog. The I/Os reserved for the watchdog cannot be used,
and no analogue and H modules can be used on the sockets with base address 240
3) Typical values; the processing time is dependent on the load on the communication ports
4) The period given is a buffer time; it is dependent on the ambient temperature (a higher temperature means a
shorter buffer time)
5) The 1 kHz applies with a pulse/pause ratio of 1:1 and refers to the total frequencies of the inputs
6) The USB port is type "USB 1.1 Slave Device 12 Mbps" and can only be used for programming and as an S-Bus
Slave, together with certain software products (Webconnect, ViSi-PLUS with S-Driver).
With a USB 2.0 hub, the download runs twice as fast
Can also be used as a serial data port, e.g. to connect a terminal; but this hampers commissioning and trouble
