Self‐Diagnostics
The In-Pulse™ ll has integrated diagnostics to determine the control and IO integrity.
Memories, processor, IO, and baseline power supply monitoring are included in the diagnostic tests.

Communications
The In-Pulse ll provides two isolated serial interfaces—one RS-232 and the other RS-485.
Both ports feature an industry-standard Modbus® * protocol (ASCII or RTU) that can interface
to a Modbus master or slave device such as a Human/Machine Interface (HMI).
These ports also support Woodward ServLink protocol for a Watch Window or Control View PC interface.
Baud rates are tunable to meet specific user requirements.
The In-Pulse ll also provides three CAN ports, one of which is isolated if requested.
All ports feature J1939 and CANOpen protocols. These ports can be used for distributed
control with other devices such as actuators, valves, other In-Pulse ll controls and 733’s
(to load share for example), and to communicate with other on-engine devices such as I/O
modules and displays.
The isolated port is well suited for communication to off-engine components like PLCs,
ship and building systems.
Programming
The In-Pulse ll is programmed using Woodward’s proven GAP™ Graphical Application Programmer.
GAP is a dedicated, high-level, block-oriented programming language specifically designed for simple
and quick implementation of difficult engine control strategies.
GAP functions are easily modified and expanded, allowing fast creation of new applications.
Adjustments
Adjustments can be made quickly and easily through the Woodward Watch Window or Control
View PC configuration interfaces. Both adjustment methods are menu-driven.
The control saves all set points to non-volatile memory uponcommand.
