1.2 Serial Port: (applicable to all T2 CPUs)
The serial port connects the T2 CPU to other serial devices, depending on the application.
Connection can be either RS232 or RS485.
The serial port can be configured for one of three protocols:
a) Modbus protocol (Slave device) is available on this port allowing easy connection to
other third party products such as DCS systems, SCADA systems and PLC’s.
b) Conet/s protocol (peer-to-peer) is available on this port for integration into Conet
Intranets. Conet/s connection allows seamless network connection between devices
with full network capability such as report-by-exception, time-stamped event streams
and remote programming. The full-duplex nature of the Conet/s protocol makes efficient
use of the serial channel. With the use of modems or other virtual circuits, efficient wide
area networks can be easily constructed.
c) User Protocol. This setting gives full control of the serial port to an application program
running on the T2 CPU. This allows custom protocols to be written in EZIFORTH and
downloaded to the CPU for maximum flexibility. Applications such as creating output for
a local printer, communicating with an operator display panel, or communicating with a
third party device using a proprietary protocol, are possible.
1.3 Programming Port: (applicable to all T2 CPUs)
The programming port is an RS232 port that implements the Conet/s protocol. This port is
used for software configuration, interrogation and program downloads using a Microsoft
Windows compatible PC, Laptop or Handheld computer.
1.4 Conet/c Network Port: (only applicable to M1241B T2C CPU)
This port provides the connection to the Conet network. Conet/c is a true peer-to-peer local
area network (LAN) that allows fast secure data transfer over long distances (up to 10km)
using a conventional twisted pair of wires.
