Dealing with objects with tag

[khalil]

Hello 
I have set of GA(1,2,3,4,...) linked to TAG (TESt)
I want the script based on GA(1,2,3,4,...) value to write something in different GA(101,102,103,104,...) 

how to achieve this  especially when multiple GA's values changed together?
with Best regards,

This will add 100 to the last group address part:

Code:

addr = event.dst:gsub('%d+$', function(a)
  return tonumber(a) + 100
end)
log(addr)

This will add 100 to the last group address part:

Code:

addr = event.dst:gsub('%d+$', function(a)
  return tonumber(a) + 100
end)
log(addr)

Thanks Admin 
and the Value?

[admin]

Use event.getvalue() as in any other event script. It does not matter if the script is attached to a tag or a single group address.

I think it will be easy for me to get only the last group address part as number, because its not the same pattern.

Also what is function(a)?

BR,

This function replaces last part of the group address with the last part value + 100.
Another option for this is to split the address into parts and then join back:

Code:

parts = event.dst:split('/')
parts[3] = tonumber(parts[3]) + 100
addr = table.concat(parts, '/')

log(addr)
