Scaling
The scaling parameters will have no effect on the values reported to Windows applications. They will be used exclusively in the Test I/O and Calibrate windows of the I/O Tool Kit. Only the actual (raw) values will be exchanged with other Windows applications. These values are typically in the signed value format in the range of -32768 to 32767.
Standard I/O Drivers
Citect HMI software includes an I/O driver (SxDirect) that communicates directly to SIXNET stations and I/O modules. The optional SCS feature set of the SIXNET I/O Tool Kit includes an exporting function that automatically configures the Citect SxDirect driver and also creates Variable tag records for the SIXNET I/O.
Standard Modbus Drivers
Modbus Ethernet and serial drivers have been incorporated into a number of SCADA, control and MMI packages. SIXNET IPm stations, SixTRAK gateways, VersaTRAK RTUs, RemoteTRAK and EtherTRAK I/O modules can be configured to respond to Modbus commands.
OPC Servers
The following OPC servers will respond to OPC messages from any Windows application that has an OPC client, then send the appropriate Modbus or SIXNET commands to the SIXNET stations and/or I/O modules:
- The KepServerEx sends SIXNET protocol over Ethernet and serial ports. A limited version (32 I/O points total) of this server is provided free of charge on the SIXNET CD, and works with SIXNET hardware only. A fully featured version of this OPC server may be purchased from Kepware Products.
- The KEPServer sends Modbus protocol over Ethernet and serial ports. This server is provided free of charge on the SIXNET CD, and works with SIXNET hardware only.
DDE Servers
The following DDE servers will respond to DDE messages from Windows database and spreadsheet programs such as Excel or Lotus, or from many SCADA and MMI packages such as Wonderware. The DDE server will then send the appropriate commands (Modbus or SIXNET) to the SIXNET stations, I/O modules or I/O database to read / write the desired I/O.
- The KepServerEx sends SIXNET protocol over Ethernet and serial ports. A limited version (32 I/O points total) of this server is provided free of charge on the SIXNET CD, and works with SIXNET hardware only. A fully featured version of this server may be purchased from Kepware Products.
- The KEPServer sends Modbus protocol over Ethernet and serial ports. This server is provided free of charge on the SIXNET CD, and works with SIXNET hardware only.
Write Your Own I/O Driver to Send SIXNET Protocol Many applications can be written to send SIXNET commands directly over Ethernet and serial ports. A SIXNET Universal Driver Development Kit has been provided on the SIXNET CD for this purpose. This kit contains detailed information on the SIXNET Universal protocol. To install the SIXNET Universal Driver Development kit, access the "Install Software" link on the SIXNET CD.
