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.
