Total 12 devices

In the list is one new device, without Addr. For add this sensor to config list we use next command. 

root@iplog:~# metel-1wire-temperature add 28.EED777911602

Check that the sensor has been added to the config list. 

root@iplog:~# metel-1wire-temperature config
Id                      Addr
28.202877911702         1

4. Creates variables for IEC 61131-3

If you have define all sensors or you did some changes, it is neccesary create actual list of varibales for one wire sensors. 

root@iplog:~# metel-1wire-temperature update_iec

Example of updating proccess 

Stopping metel-1wire-temperatured: OK
Starting metel-1wire-temperatured: OK
Stopping IEC 61131-3
Starting IEC 61131-3

Now are variables available for programming in Metel IEC 61131-3 program.
