Hello. 1
In this video we are going to learn. 2
Station Number definition this will be very short video because this is really important point when 3
we are trying to build a communication. 4
We need to define our comm ports and we need to set our station numbers in special data registers. 5
For example if we want to use Com1 RS232 communication and com2 RS485 6
ports for plc. 7
So for the station number we need to send our station number to d1121 8
data register 9
This is for the com 1 and com 2 communication and M1002 is it will. 10
It is going to be active. 11
Just one pulse when plc is at run situation and for the COM3 this is also RS485 12
port communication port we need to send our station number master address to D1255 13
data registers. 14
These are special data registers and these are really important while we are starting to build our serial 15
communication while we are working with the coms ,com1 , com2,com3 for the RS232 16
and RS485 communications we need to watch out this so I am finished 17
for this video see you in the next video.
