HARDWARE:
Is possible an hardware-forcing of IP addresses using jumpers J4 of the electronic board. An IP address is
composed by four fields (A.B.C.D) , by inserting jumper in 1-2 of J4 ( before power-up the electronic board
) you willset field A , the number that you want to override is settable by switches of SW1.So inserting
jumper on 3-4 of SW1 you will set field B , on 5-6 field C , on 7-8field D. For example if you want set
address 1.1.1.1 when unit is off put jumper on 1-2 of J4 and SW1 with the first switch to on (1) . Power-up
the unit and so the first field is writed, turn-off and move the jumper to 3-4 , the switch SW1 remain the
same cause we want to write another 1 , instead if we wanted to write another number we had to change
positions of it. Repeat the same procedure for field C and D. Is important to remember that SW1 is in
binary mode, so the first switch ON means 2^0,the second 2^1, the third 2^2 and so on. For example if you
want to write number 5 you have to convert it in binary mode (101 : 1*2^0+0*2^1+1*2^2=5) and set to ON
the first switch ,to OFF the second and to ON the third.
TRANSACTION TABLE
The configuration parameters, the set point, the input signals, the working states and the alarms, are
th
accessible as holding registers (word 16 bit access). BXX is the XX bit of a word (XX is a value from 00 up
to 15). R is indicating a only readable word, R/W is indicating a readable and writable word.
