Ladder Logic Function Blocks
Subroutines
Subroutines are not currently supported using W INTERPRET .
If a PDS ladder logic function block contained a CALL
element PDS2WIN will convert the function block to a
W
INTERPRET source file. However, when the function block is
opened and compiled in W INTERPRET an error “Compilation of
Call is not yet implemented” will be displayed. You must
remove the call instruction from the function block before it
will compile successfully and can be loaded into a Regent.
Rung and Cell Comments
Ladder logic rung comments are converted (except for those
that were entered for empty rows). Cell comments that may
have been entered in the PDS ladder logic function blocks are
not converted. In W
INTERPRET , cell comments in ladder logic
are automatically linked to the description of the variables (as
entered in the I/O and shared variable editors).
Ladder Logic Title Page
The title page of a PDS ladder logic function block is
converted to the W
INTERPRET function block file details.
ASCII Function Blocks
In W INTERPRET , the ASCII output function is now part of the
ladder logic instruction set. Therefore, ASCII output function
blocks from PDS are converted to W
INTERPRET ladder logic
function blocks.
Each ASCII output message is converted to an individual
rung of ladder logic containing the new ASCII output element
(see below). The start tag becomes an up-transitional contact
connected to the input leg of the ASCII element, the done tag
becomes a coil connected to the top output leg of the element,
and the error tag becomes a coil connected to the bottom
output leg of the element. The messages do not have names.
