2 GENERAL NOTES
In order to have a correct and co plete picture on the use of DLC_1200SG and how to work with this object, it is
appropriate to give so e general infor ation. The DLC_1200SG is an expansion odule, that can be connected to
Kernel devices, whose ain characteristic is that they have 1 analog strain gauge input at 16 bits. Moreover,
thanks to an addressing syste to 5 bit you can give to each expansion node address fro 1 to 31.
2.1 DIP-SWITCHES
You can configure for each DLC_1200SG its own node address, baud rate and protocol, through the 8 suitable dip-
switches (see hardware characteristics and the following figure).
Here are so e exa ples that help to understand :
In the application progra of the PLC of the Kernel Siste i you need to set the NUMBER and the TYPE of
EXPANSIONS that are connected. To do this it's necessary to open the project and go into the enu "Project
Options" >> table "Serial" to set the nu ber of expansions; click on the button "Configuring Expansion" to choose
the type of expansions connected.
With the KNP protocol you can insert in the network different types of Kernel Siste i expansions.
IMPORTANT : he node address of each expansion se wi h he dip-swi ch mus MATCH he one assigned
au oma ically by he applica ion program of he PLC of he Kernel Sis emi [see figure below] :

2.2 Communica ion
The serial communica ion occurs only via RS 485. I will be necessary o se he pro ocol KNP_MASTER 19200,
N, 8, 1, on he PLC Kernel Sis emi.
With the dip-switches 1 and 2 you select the COMMUNICATION PROTOCOL and with the dip-switch 3 you choose
the BAUD RATE; according to the protocol set with the dip-switches, you need to select the corresponding
protocol (within the PLC project) in the COM used between PLC and expansions. Also in this case it's necessary to
open the PLC project and go to the enu "Project Options" >> table "Serial" to select the correct protocol :
DIP-SWITCH 1 e 2 - Project Options >> “Serials” of the PLC project
-------------------------------------------------------------------------------------
= KNP (Kernel Network Protocol) – KNP MASTER
1 = KERNEL Protocol - KERNEL
11 = MODBUS RTU Protocol - RTU MASTER
Also the Baud Rate set with the dip-switch ust obviously coincide with the one selected in the "Project Options"
>> table "Serial" in the COM used between PLC and expansions.
3 Memory Map
Currently the DLC1200SG has two 16 bit (1 WORD) e ory location called DATA which allow to read the current
strain gauge value.
