LDBT (Load Bit), LDBTI (Load Bit Inverse)

Functions

-These instructions are used to read the bit data assigned to S2 among the word addresses in Device D assigned to S1, starting the operation for Contact A (LDBT) and the one for Contact B (LDBTI). The information (On/Off) on the assigned device are received and taken as the result of their operation.

Example)

If the 3rd bit of D0000 is turned on, Output Y12 is turned on.

ANDBT (AND Bit), ANDBTI (AND Bit Inverse)

Functions

-These instructions are used to read the bit data assigned to S2 among the word addresses in Device D assigned to S1, connecting in series with Contact A (ANDBT) and Contact B (ANDBTI). The information (On/Off) on the assigned device are received and taken as the result of their operation.

Example)

Turning on X00 and the 3rd bit of D00 turns Y20 on.

ORBT (OR Bit), ORBTI (OR Bit Inverse)

Functions

-These instructions are used to read the bit data assigned to S2 among the word addresses in Device D assigned to S1, connecting in parallel with Contact A (ORBT) and Contact B (ORBTI). The information (On/Off) on the assigned device are received and taken as the result of their operation.

Example)

Either turning on X00 or the 3rd bit of D00 turns Y10 on.
