A provision of depiction of data accepts a decimal digit in form BCD (Binary Coded Decimal with four binary signals) and him portrays as tendency in the interval 0 – 10 Volts. Program this operation in the PLC of type S7 – of 200 Siemens using voltmeter direct current for the depiction of tendency. In order to we have tendency 0 – 10 VDC it should we give a cetane number 0 – 32760 (eg for 5V it should we give 16380).

I have made some progress but i am confused on how to change the decimal in BCD.
 
Hello !
Is this some school task again ?

NETWORK 1
//
LDW= AIW0, 0
= Q0.0

NETWORK 2
//
LDW>= AIW0, +6552
= Q0.1

NETWORK 3
//
LDW>= AIW0, +9828
= Q0.2

NETWORK 4
//
LDW>= AIW0, +13104
= Q0.3

NETWORK 5
//
LDW>= AIW0, +16380
= Q0.4

NETWORK 6
//
LDW>= AIW0, +19656
= Q0.5

NETWORK 7
//
LDW>= AIW0, +22932
= Q0.6

NETWORK 8
//
LDW>= AIW0, +26208
= Q0.7

Am i in the wright path or ... ?
