LON address assignment for CS6 Guarto MP3
The LON communication between NK822x and Guarto MP3 is based on logical
BACnet addresses for both devices.
The physical LON address of the NK822x LON interface is configurable, whereas
the logical BACnet address of NK822x is fixed.
The default physical LON address of NK822x is:
Subnet: 01
Node: 02
The logical BACnet address of NK822x is fixed to 1. This address has to be con-
figured in the CS6 using the tool SWE6 for Guarto MP3 (Node CerCom Bus, prop-
erties of node Management Station).
– The physical LON addresses and the logical BACnet addresses have to be
unique in a LON-network.
– Guarto MP2b is not supported in NK8000 MP3.15 / MP3.18.

C interface
This interface allows for a direct support of:
Direct digital input/output:
– One or two DF8040 (CF9040) input modules
– One DF8020 (CF9020) output module
Power supply supervision:
– One DF8090 power supply supervision module
All the optional modules can be installed on the DIN-rail, next to NK822x unit.
DF8020
DF8020 is a module providing 8 relay outputs, NO or NC.
See Fig. 19 on page 29 for the connection of I/O modules to the NK822x;
See also CF9003 documentation (e1762b) for mode details on DF8020.
DF8040
DF8040 is a module providing 8 inputs, which can be normally open or normally
closed and driven by dry contacts or open collector signals
See Fig. 19 on page 29 for the connection of I/O modules to the NK822x;
See also CF9003 documentation (e1762b) for more details on DF8040.
