(1) For further information, refer to the Fixed Hardware Style Installation and Operation Manual , Publication
1747-6.21.
(2) 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.
(3) This specification does not include input and output values. ( S ee page 17.)
(4) This applies only to fixed controllers that have ac line power and dc input circuits.
