Citect
and SIXNET |
|
| There
are several ways to interface SIXNET controllers, RTUs and I/O to
Citect HMI software. |
| |
- SIXNET
Direct Driver: Use Citect's SIXNET direct
(SxDirect) driver over a Ethernet or serial connections to interface
to SIXNET stations. This driver uses the SIXNET protocol to
communicate directly to SIXNET stations. In addition, with serial
port connections, this driver can be used with Citect's standard
modem dialing and callback features. The SIXNET
I/O Tool Kit (with option group 2) also provides an advanced
tag export feature that automatically sets up the Server, Boards,
Ports, I/O Device, and Variable forms in Citect . One click
of a button exports all your tag definitions to Citect. (Note:
The SxDirect driver and SIXNET utilities cannot communicate
out the same serial port at the same time. They can
communicate at the same time over Ethernet.)
- SIXNET
OPC/DDE Server: SIXNET offers an OPC/DDE
to SIXNET Server. This server use the advanced SIXNET protocol
to communicate over Ethernet or serial connections to SIXNET
stations. It then makes the I/O available to any client software
that supports OPC (v2.0), DDE, FastDDE, or
AdvancedDDE. A free license for up to 32 I/O and/or 2 stations
is provided for the SIXNET driver. For more I/O or stations
or to run other drivers, additional licenses can be purchased
directly from www.kepware.com.
- Modbus
OPC/DDE Server: SIXNET offers a free
OPC/DDE to Modbus
Server. This server use the Modbus
protocol to communicate over Ethernet or serial connections
to SIXNET stations. It then makes the I/O available to any client
software that supports OPC (v1.0), DDE, FastDDE,
or AdvancedDDE.
- Modbus
Direct Drivers:
You can also use Citect's standard Modbus
(Modbus RTU over serial port), ModbusA (Modbus ASCII over serial
port), or Modnet (Modbus over Ethernet UDP or TCP) drivers.
The Modbus serial port drivers can be used with Citect's modem
dialing and callback features. See Technical Notes #608
(PDF) and #626 (PDF).
(Note: With serial connections, you can't communicate to the
SIXNET stations with SIXNET software utilities at the same time
they are being polled via Modbus ASCII or Modbus RTU.)
