Convert the INTs to DINTs
Enter the following rung:
After the MSG instruction reads data from a module (
BTR.DN
is on), this rung converts the INT values from the BT module
to DINT values for use in the project:
•
The MOV instruction sets the length of the FAL instruction equal to the number of elements that the MSG reads.
•
The FAL instruction then loads the values from
BTR_int_buffer_read
into
BT_input
. This converts the values to
DINTs for use in the project.
•
BTR_index
determines where in the first dimension of
BT_input
to store the values. Each element of this
dimension corresponds to a specific BT module.
