Mark VIe I/O modules
Mark VIe I/O modules have three common components: a termination block for field wiring, a terminal board, and I/O pack(s). Modules are DIN rail mounted. Wide gauge wiring eliminates marshalling and lowers costs. Each I/O pack contains two IONet ports and a local processor with a real-time clock synchronized for 1ms time-stamping in the sequence-of-events (SOE) function available on all discrete inputs and outputs. This feature allows customers to select SOE with the click of a button, without the complexity and expense of dedicated SOE hardware. I/O diagnostics and voting are performed at the pack level. Simplex I/O modules have one I/O pack mounted on the terminal board; TMR I/O modules have three I/O packs mounted to a common terminal board. I/O redundancy is a single selection during hardware configuration, and is transparent to the application code.
IO network (IONet)
The IO network is a dedicated, full duplex, point-to-point protocol. It supports a deterministic, 100 MB communications network suitable for local and/or distributed I/O modules. IONet switches are a GE design, incorporating extreme environmental capability with superior performance. Standard network protocols such as Profinet, Profibus and Foundation Fieldbus can be seamlessly integrated into the Mark VIe system.
Virtual Mark VIe controller
For training and validation, simulation of the process and associated control can be invaluable. The Virtual Mark VIe provides a virtual, PC-based form of the controller supporting:
• Execution of application program
• Communication interface with ToolboxST application
• Ethernet Global Data (EGD) services
• Process alarm management
