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 suggested that external interrupt subroutines not be used with high-speed counters. Latched settings for all devices in EH2/SV series MPU: *1: K-1 refers to the default setting is non-latched.
