2.2.1 Programming Port
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. This port is compatible with the
Omniset configur
ation utility, and the Omniflex ISaGraf Programmer’s Workbench.
2.2.2 Serial Port
All P3 CPU’s are equipped with a serial port that can be used to connect to other serial
devices. Connection can be either RS232 or RS485.
The serial port can be configured for one of two protocols:
a) Modbus Slave protocol (ASCII or RTU) is available on this port allowing easy connection
to other third party products such as DCS or SCADA systems.
b) Modbus Master protocol (ASCII or RTU) is available on this port allowing easy connection
to third party Modbus Slave devices.
c) 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.
2.2.3 Conet/c Network Port
This port provides connection to a Conet/c industrial network. Conet/c is a true peer-to-peer
local area network (LAN) that allows reliable data transfer between multiple nodes over long
distances (up to 10km) using conventional twisted pair cabling found in most industrial plants.
2.2.4 Ethernet Network Port
This port provides connection to a 10/100 Ethernet network via a UTP connector on the front
of the module. The Ethernet port supports two protocols running under the TCP/IP transport
protocol:
•
Modbus/TCP (Slave and Master)
•
Conet/e (providing full support for all Conet features over Ethernet including remote
programming, and time-stamping at source)
These two protocols can co-exist on the Ethernet link
