External Interface Protocols
External interface protocols support transmitting and receiving data with third-party control, monitoring, and supervisory
systems through the Plant Data Highway (PDH). Communication is important but normally not critical to control and
equipment protection. The protocol types include:
• Variable feedback and commands to and from a third-party Distributed Control System (DCS)
• Alarm annunciation and management interface with third-party systems
• Interface with third-party industrial protocol gateways
Equipment Control and Configuration Protocols
The Unit Data Highway (UDH) and IONet networks use several different protocols for equipment control and configuration,
as described in the following table.
Equipment Control and Configuration
Protocols
Ethernet Global Data (EGD)
Network Time Protocol (NTP)
System Data Interface (SDI)
OPC-UA Server
Precision Time Protocol IEEE 1588
F Fieldbus HSE
OUNDATION
Fieldbus Network Protocols
Fieldbus protocols network field devices (sensor and actuators) with the control system, enabling diagnostic and configuration
functions along with traditional real time control. The Mark VIe system supports the following protocols:
• F Fieldbus
OUNDATION
• PROFIBUS -DP
• HART communications
• CANopen communications
• Modbus Master RS-232, 422, 485
• Modbus Master Ethernet
• PROFINET

Functions
• Feedback and commands between HMI and Mark VIe controllers on UDH
• Control data between Mark VIe controllers on UDH
• Real time data between I/O modules and Mark VIe controllers on IONet
• Redundant controller data synchronization
Clock synchronization between Mark VIe controllers, I/O packs, WorkstationST
PCs, and a master time source. NTP operates on both the UDH and IONet
networks.
• ToolboxST configuration and monitoring with controllers, I/O packs, and
WorkstationST PCs
• Real time alarm annunciation and management between controllers and
WorkstationST Alarm Server
• Transmission of trip log data from controllers to WorkstationST Alarm
Server
Mark VIe controller interfaces with OPC-UA client functions on UDH network
IEEE 1588 is designed for local systems requiring high precision that cannot
afford the a GPS receiver at each node. The standards describe a hierarchical
master-slave architecture for clock distribution.
Mark VIe implementation of HSE is used to couple the controller with the linking
device (gateway between IONet and H1).
