➀ The scan times are typical for a 1K ladder logic program consisting of simple ladder logic and communication
servicing. Actual scan times depend on your program size, instructions used, and the DH-485
communication.
➁ This specification does not include input and output values. (See page 1-6 .)
➂ This applies only to fixed controllers that have AC line power and DC input circuits.
