SPA bus communication speeds

Table 3.3.3.2-1 Communication speeds
Baud rates supported
1.2 kbit/s
2.4 kbits/
4.8 kbit/s
9.6 kbit/s
19.2 kbit/s
38.4 kbit/s
The SPA baud rates can be set through the Profibus-DPV1/SPA Configuration Tool
(PCT), to match the connected relay. If several relays are connected, they all use one
common baudrate.

DIP switch configuration

The SPA interface is configured by using DIP switches located beside the DSUB9
connectors. To select the correct DIP switch number, follow the instructions in
Table 3.3.3.3-1 and see Fig. 3.3.3.3.-2:
For the safety, set the active DIP switches to OFF position before
switching on the new settings when changing the interface type.
Only one interface type must be active at a time. The state of the DIP
switches can be changed without turning the power off.
The smaller group of DIP switches is referred to as group A, and the
larger group as group B, see Fig. 3.3.3.3.-2.
