1. LDI applies to contact B that starts from the main line or contact B that is the start of a contact circuit. Use it to save
the current contents, and store the contact state in the accumulative register.
2. ANI connects contact B in series. It reads the state of the contact that is specified as connected in series, and
performs the AND operation with the previous logical operation result. It stores the final result in the accumulative
register.
3. ORI connects contact B in parallel. It reads the state of the contact that is specified as connected in parallel, and
performs the OR operation with the previous logical operation result. It stores the final result in the accumulative
register.
Example
1.
Contact B of X0.0 is loaded, contact B of X0.1 is connected in series, contact B of X0.2 is connected in parallel, and
the coil Y0.0 is driven.
2.
When both X0.0 and X0.1 are ON, or when X0.2 is ON, Y0.0 is ON.
