Hi experts,

For your kind information

we have a data type of UInt in TIA. so we can add two integer and made one Dint easily i think so

IBN-Service

Sorry, but is'nt it much easier this way:

L MD 100
T MD 200

That is the easiest way for the demo I have done, but as you know every thing is not that easy.If Words are not adjacent (or different in nature or from different DBs) my solution is still efficient (5 instructions compared to 6 instructions plus extra memories in a general solution):

[code]//What IBN-Service Suggests
L DB1.DBW 0
T MW 100
L DB2.DBW 0
T MW 102
L MD 100
T MD 200

//My suggestion
L DB1.DBW 0
