For each tag to be scanned, create a string element following the OptoScript Syntax and tag naming standard.
IMPORTANT: Index number 0 (zero) must be the last item initialized in the OptoScript block
...
Code Block | ||
---|---|---|

/* |
...
If the tag begins with an ' or a /, the tag is ignored. |
...
Important! Initialize the first table element (at Index 0) last (because |
...
a blank string in Index 0 tells the driver that the |
...
string table has not yet been initialized). |

To construct the tag name, see Naming Standard.*

...
In the OptoScript block, you reference PAC Control tags using a pre-defined naming standard that consists of the tagís:*

Naming standard: <OptoScript data type code>.<PAC Control tag name>[<index number or range>].<bit location>.< writeable attribute>
