General Features
 
1 A user interface called the PowerTool for configuring channels, devices, and datablocks.  Statistical communications data is provided for throughput analysis at each level.
2 The PowerTool has a built-in datascope for checking Host-to-RTU and RTU-to-Host communications messages.  The PowerTool also has context sensitive help.
3 Direct, Radio, and Telephone communication modes.
4 Automatic reads after a write to confirm a write.
5 Automation Interface - You don't have to use the Power Tool to configure the driver.  You can make your own COM or OLE application (using Microsoft's Visual Basic) to configure the driver and access data. 
6 Secondary Poll Rate - The OPC Server polls a datablock at the secondary poll rate once the Access Time expires.  Data is polled at the secondary poll rate until there is another client request for data.  If  the secondary poll rate is set for a longer period of time than the Primary Rate, CPU resources are reduced while ensuring that the datablock will always be polled.
7 Phased Poll Rates
8 Enable/Disable individual communication channels, devices, and datablocks from the automation interface or your HMI.
 
Modbus Ethernet Features
 
1 Supports redundant Modbus Ethernet networks.
2 Supports multiple simultaneous connections to the same device.
3 Supports redundant devices (devices can have the same IP address, port, and unit ID).
 
Modbus Plus Features
 
1 Supports redundant Modbus Plus networks.
2 Supports use of multiple master paths.
3 Supports redundant devices (devices can have the same routing path).
4 Supports global data, including writing to local node global data.
