i needed to manipulate some binary data within the scada that is then encoded into the word...

i.e.

b0-b15 -> w0

so i created a virtual data source, added some binary tags...

then created a meta source word, added the b0-bx as context variables and then did...

value=0;
if (b0.value==1) value=value+1;
if (b1.value==1) value=value+2;
if (b2.value==1) value=value+4;
if (b3.value==1) value=value+8;
return value;
word.value=value;

this gave my word value...

then i did a point link between meta source word and real slave device word...

could i have done this in a more economical way?

i did try adding the slave device word with direct binary tags, but it dint like that...

but was quite happy with word to word control

thanks
