The ST-GT-1210
is a IEC 61131 programmable
I/O controller for process control, SCADA, and RTU applications. It
can control up to thousands of points from EtherTRAK
Ethernet I/O modules, RemoteTRAK
RS485 I/O modules, SixTRAK
Local I/O modules, and third party Modbus devices. It has a RS232
ports, a RS485 port, and a 10/100 Ethernet port. In addition to the
full IEC 61131 programmability, it has all the features of the EtherTRAK
I/O Concentrator or EtherTRAK
Ethernet I/O Expander.
Yes. You cannot
communicate directly to SixTRAK
I/O modules. They can only connect to an EtherTRAK
I/O Concentrator, EtherTRAK
I/O Expander, SIXNET
controller, or SIXNET
RTU. If you want to interface to I/O modules directly then you
can use either the EtherTRAK
Ethernet I/O modules or RemoteTRAK
RS485 I/O modules.
Though they can
both perform stand alone control a SixTRAK Programmable I/O Controller
possess several advantages. First, unlike a PLC, these I/O Controllers
were designed to be real-time extensions of Windows-based data acquisition
and control systems (what we call "I/O
for Windows"). Some of the standout features of an I/O Controller
over a PLC are more
open programmability (IEC 61131), greater
I/O expandability, more
advanced analog I/O support, and more flexible communications.
An I/O Controller's
Ethernet port supports the Open Modbus/TCP protocol per Modicon's
specifications from www.modicon.com. It also support Modbus over
UDP which is faster than TCP but has less error checking. In addition,
it supports the SIXNET protocol over either TCP or UDP. The I/O Controller's
serial (RS232 or RS485) port(s) support Modbus ASCII, Modbus RTU,
or SIXNET protocol. Both master and slave modes are supported.
Most likely because
there are several methods for interfacing to SIXNET stations. The
first is with the SIXNET IOmap interface which comes as an option
to the SIXNET I/O Tool
Kit software. This shared database supports OPC, DDE, and direct
DLL calls. SIXNET also offers a
Modbus OPC Server that talks Modbus/TCP and provides access via
OPC or DDE. A third method is to use the Modbus/OPC driver that comes
with most HMI/SCADA software.
Yes. Each port
can be individually configured for a different protocol and mode (master
or slave).
Sure. The best
way is to use an operator interface that can act as a Modbus master.
These displays are widely available and inexpensive. Also, no programming
is required I/O Controller because these displays are configurable
on their own. We have tested the TCP, Exor, CTC, and other brands
of displays. Refer to our Technical
Notes for details.
Sure. Just install
TCP/IP (if you’re not using it already), set your IP addresses,
and your all set to talk to your SixTRAK
I/O Controllers. Most Ethernet networks can run multiple protocols
(i.e. NetBEUI, IPX/SPX, TCP/IP, etc.) all at the same time.
Yes. If your SixTRAK
I/O Controller is connected to a network with Internet access,
then you can access it from any where in the world just by specifying
it’s IP address.
Absolutely. Communications
over radio or telephone modems is a snap for the SixTRAK
I/O Controller. For radio modems, both the dumb (requires I/O
Controller to control transmitter keying) and intelligent (automatic
transmitter keying) variety are supported. For telephone modems, a
ISaGRAF function
block makes it easy for the SixTRAK I/O Controller to dial and make
connections to other stations or the master site. In addition, these
I/O Controllers also support leased-lined, short-haul, or any modem
that can be interfaced via a serial port. Refer to our Technical
Notes for details.
Yes. The Sixlog
option of the SIXNET
I/O Tool Kit software makes it a snap to perform datalogging in
a SixTRAK I/O Controller
which can have up to 512K of RAM. With this much memory you can log
more than 6,500 records of 16 analogs, 64 discretes, and 6 floats.
If you’re logging once a minute then you can log for 6,500 minutes
or 4.5 days before filling up the memory.
Easily. No programming
is required to perform peer-to-peer I/O moves between a SixTRAK I/O
Controller and other SIXNET controllers
or RTUs,
EtherTRAK Ethernet I/O,
RemoteTRAK RS485 I/O, or third party Modbus devices. Just use
the SIXNET I/O Tool
Kit software (SCS option required) to configure your peer-to-peer
I/O transfers.
