Tips
Solution when connecting one-digit data of a BCD digital switch to inputs 0100
to 0103, while ignoring other inputs
Only one-digit data of the BCD digital switch is transferred as the setting value of the
fetching counter (C004).
Other inputs (0104 to 0115) are ignored.
Application of ANDA instruction
Fetch input data separately
Sets the low-order 2 digits of the BCD digital switch (7000 to 7007) to counter C000
and the high-order 2 digits (7008 to 7015) to timer T001.
