2 Functions of Devices in DVP-PLC *1. Non-latched area cannot be modified. *2. The preset non-latched area can be modified into latched area by setting up parameters. *3. The preset latched area can be modified into non-latched area by setting up parameters. *4. The fixed latched area cannot be modified *5. The speed at which an external interrupt subroutine is executed depends on the size of the external interrupt subroutine. It is *6. If a PLC is connected to right-side special modules, and M1183 is reset to OFF, the data registers will be available. Every suggested that external interrupt subroutines not be used with high-speed counters.
right-side special module connected to a PLC occupies 10 data registers. *7. If a PLC is connected to left-side special modules, and M1182 is reset to OFF, the data registers will be available. Every left-side special module connected to a PLC occupies 10 data registers. *8. Please refer to section 2.9 for more information.
