Design and Interfaces
Setup
The PICO controller has the interfaces shown in the diagram above. Optional Channels 3 and 4 can be added later
with a plug-in card. When controlling with the PLC, it is advisable to supply the binary communication signals with
the external PLC operating voltage galvanically isolated from the PICO controller (refer to the circuit diagrams under
“Technical Data” on page 52).
The PICO controller works on the basis of a microprocessor. Parameters are set using an ASCII TXT file and
SD card or by using the fieldbus communication interface. Parameters can also be adjusted locally on the PICO
controller (within set limits ) by using the Menu dial and the Enter and ESC (escape) keys on the front of the unit. The
display shows the current values.
