Control Communication Interfaces
A complete Modbus list of information is available for HMI, plant DCS or other control interfaces. Three
channels are available for this communication method, 2 Ethernet (RJ45) ports and 1 serial port. The
serial port protocol can be either ASCII or RTU and the communications can be RS-232 or RS-485. The
Ethernet links are TCP on either ENET ports 1, 2, 3 and 4.
The control also communicates Servlink protocol (Woodward proprietary) via the Ethernet ports. Using
Woodward’s Servlink to OPC Server tool any PC can use this connection to communicate to the control
and relay OPC data to the various service tools that support the product.
CAN
The CAN communication ports are available for interfacing the control application with other products.
This feature is not being used.
