Appendix C Quickstarts
These variables use a combination of decimals and binary numbers to
specify the embedded outputs that are able to turn on/off.
Thus, in our example, we first set the Output Mask to a decimal value of 3
which, when converted to binary, is equal to 0011. This means that now
outputs O0 and O1 can be turned On/Off.
We have set the HPOutput to a decimal value of 1, which, when converted
to binary, is equal to 0001. This means that when a High Preset is reached,
output O0 will turn on and stay on until the HSC is reset or the counter
counts back down to a Low Preset. The LPOutput works same way as the
HPOutput except an output will be turned on when a Low Preset is
reached.
Assign Variables to the Function Block
1. Go back to the ladder diagram and assign the variables you have just
configured to the corresponding elements of the HSC function block. The
HSC function block should appear as shown in the screenshot:
To assign a variable to a particular element in your function block, double
click the empty variable block. On the Variable selector that appears,
choose the variable you have just created. (For example, for the input
element HSCAppData, select the variable MyAppData.)
