Citect
links to SIXNET I/O through a shared tag database that exchanges
information through lightning fast direct DLL calls. Now, the
new SxDirect I/O driver (supplied as an integral part of Citect
at no extra charge) creates a direct link between Citect and
SIXNET I/O taking advantage of all of Citect’s latest
advances, including their unique remote access capabilities
that allows remote stations to report on exception.
Tag
Sharing Saves You Time
Create
I/I Tag definitions just once and then share them between the
SIXNET I/O Tool Kit (configuration software) , Citect and your
ISaGRAF program with the SCS pre-integrated tag sharing. The
SIXNET and Citect tag definitions are 100% compatible (they
were created together as a cooperative engineering effort) to
seamlessly share I/O tag data. The result is that you will save
days or weeks of tedious configuration time. Even better, you
won’t have to find the typographical errors that manual
data entry can cause, so you can skip a big part of the debugging
process when the time crunch occurs at start up.
Scalable
Systems Technology
Start
small and let your systems grow gracefully with the scalable
architecture of an SCS solution. Both Citect and SIXNET share
the belief that systems should be modular and the SCS (scalable)
concept applies to both hardware and software components of
the system. Buy just what you need. Expand later by just adding
more nodes. Performance never degrades and there are no big
cost surprises waiting for you when you expand your system.
SCS
gives you Growth Without Limits.
Hot
Backup Datalogging
Datalog
files in SIXNET gateways and RTUs can be uploaded into Citect
and synchronized with Citect historical files. This allows the
remote data files to serve as a back up to Citect – in
effect to keep logging even if your computer is offline. This
same capability allows remote stations to report in periodically
and fill in historical data on a batch basis. Sample Cicode
is available for this powerful capability. (Ask for the Cicode
from the SCSdemo project.)
Reliability
Through Redundancy
SCS
users build redundancy into their systems with Citect hot backup
servers, redundant Ethernet I/O nodes, and redundant ISaGRAF
controllers (SIXTRAK gateways or VersaTRAK RTUs). The possibilities
are endless – but even better – after years of successful
SCS installations, redundant SCS systems are field proven to
meet your expectations. Consult your factory-trained SCS distributor
for further applications information.
Remote
Access Manager
Citect
offers a unique capability for remote stations to "report
on exception". If you are using SIXNET hardware with Citect,
the SIXNET Control Room or a VersaTRAK, acting as a Master Terminal
Unit, can establish a two way link between the Citect I/O server
and remote I/O stations. Yes, the link into Citect can be both
a master and a slave at the same time! On large SCADA systems
this allows you to poll the distributed stations and also accept
"report on exception" call-ins when an alarm occurs.
This is a major advantage in water treatment, pipeline systems,
environmental monitoring and other distributed systems.
Are
you using PLCs? They too can dial into a central Citect server
using the SIXNET self-dialing modem. This industrial modem has
a built in micro-computer that handles all aspects of establishing
a phone connection and telling Citect which PLC has dialed in.
All that is needed from the PLC is a single contact closure,
indicating the exception condition and requesting the connection.
The SIXNET self-dialing modem was designed to Citect specifications
and is available through all
Citect distributors worldwide. |
