DIP-Switches
Changing the settings of any DIP-switch or jumper is permitted in power-off
state only. Modifying these settings in power-on state will possibly lead to an
undefined behavior and cause permanent damages.
3.4.1 ASIC Interface Configuration ( S1 )
Bits 1 to 3 of the DIP-switch S1 select the interface mode of the PROFIBUS
ASIC. If the VPC3+ PROFIBUS Board is used together with the
AT89C5132 controller board S1.4 needs to be set to OFF. It needs to be
set to ON if a 3
Board is directly connected to the customer electronic.
