In 2006, Citect Pty Ltd was acquired by the Schneider Electric group.^[2]

At the end of 2008, Citect ceased trading as an independent company and all of its remaining operations were absorbed into Schneider Electric.

Products[edit]

Ampla[edit]

Ampla is Manufacturing Execution Systems (MES) software.

Cicode[edit]

Cicode is a programming language used by Citect SCADA software. The structure and syntax of Cicode is very similar to that of the Pascal programming language, the main difference being that it does not include pointers and associated concepts. Citect provides a rich programming API that includes sophisticated programming constructs such as concurrent tasks and semaphores.

A Cicode sample is shown below. The function is used to log information to a file.

CitectSCADA[edit]

CitectSCADA is a HMI / SCADA software package supporting

• an extremely wide range of Schneider Electric and 3rd party PLCs (using vendor's OPC driver or its own native drivers) and
• a big collection of symbols of industrial equipments for drawing the application scenes

made by Citect with

• a design-time HMI/GUI construction tool (called Citect Graphics Builder) and
• a run-time application logics expressed in the Cicodeprogramming language.

Citect for DOS[edit]

Martin Roberts wrote Citect for DOS, released in 1987, as a response to the limited range of PC-based operator interface software available at the time. Citect for DOS consisted of a configuration database (in dBase format), a bitmap (256 colour raw format) and an animation file. The user would draw a representation of a facility using the readily available Dr Halo graphical package and placing 'Animation Points' in the desired location. 'Tags' were assigned in the configuration databases, equating to addresses within the programmable electronic devices Citect was communicating with. By referencing these tags at animation points using other configuration databases, the user could show the state of equipment such as running, stopped or faulted in real-time.

Citect for DOS could communicate with various programmable electronic devices via the various serial links offered by the device; some through direct PC serial port connections, others through 3rd party PC based cards designed to communicate with the target programmable electronic device. Software drivers were written for many protocols; its ability to communicate with a variety of devices - and to have new drivers written when required - became a primary selling point for Citect.

The runtime software ran on a DSI card; a 32 bit co-processor that was inserted into an available ISA slot in the PC. This was due to insufficient processing power available in the 286 and 386 PCs available at the time.

Citect for Windows[edit]

During the early 1990s PC computational power had caught up and Microsoft Windows based software was becoming popular, so Citect for Windows was developed and released in 1992. It no longer needed the DSI card to run on a PC. The configuration methodology remained similar to Citect for DOS but became more intuitive under MS Windows. Citect for Windows was written as a direct response to a request by Argyle Diamonds. The company was originally intending to use a Honeywell system until a number of Arygle's site engineers talked Argyle around to Citect after highlighting the existing problems they were having with Honeywell systems on site. Argyle contributed $1 million to the development of Citect for Windows. To this day the 'ArgDig' alarm database (i.e. Argyle Digital) is still part of Citect.

In 1993 BHP Iron Ore upgraded its Port Hedland operator interface to Citect for Windows. Being the largest installation attempted by Citect at the time, Version 1 was showing many limitations. Version 2 was developed to improve on these limitations. Key changes were made to the graphics configuration by Andrew Allan, including a move away from Dr Halo/Animation Point to the new 'CTG' (Citect Graphics) system. A CTG combined the old BMP/AN files into a single object based file that gave the user a WYSIWYG look when using the new drawing package. The Port Hedland scope of work required additional functionality not inherent in Citect for Windows, but due to the versatile nature of the software (in particular by the use of Cicode) many additional features were programmed.

Version 3 of Citect for Windows was developed to build in much of the functionality that previously had to be programmed, such as indication of a communications failure to any programmable electronic device displaying real-time data. While version 2 tended to be a bit unstable, version 3 was quite robust. Version 4 was the same as Version 3 but ported to suit the 32 bit platform of Windows NT.

At this time Citect for Windows had the dominant market share (in Australia) of PC based operator interface software but new competitor software was catching up to the features and functionality of Citect and gaining in popularity. Citect began to focus more on remaining competitive; version 5 was released containing mainly features aimed at keeping the software at the leading edge of the market. Version 6 continued this trend and included more SCADA-like functionality in addition to the poll-based real-time control system that still remains the core of the Citect software today.

Version 7 was released in August 2007. A. This version is also the first version to support Windows Vista Operating system. Support for Windows 7, along with notable features such as Pelco Camera integration, was added in 2010 with the release of version 7.20.^[3]CitectSCADA 2015 release on 2 July 2015^[4]

Version 8 was released in 2016, with an overhauled UI and support for Windows 10.^[5]

Introduction

In large applications where CitectSCADA has to talk to many Siemens PLC's, a need has arisen to have a higher performance Siemens Driver interface. Simatic Net has a lot of limitations on the number of PLCs it can connect to and also the performance of the Siemens API has been an issue. Citect also needed a way to optimise the way the SCADA communicates to the PLCs, because it was too easy to build setups that overwhelmed the S7NT driver - particularly if the user attempted to poll large configurations of Function block instance DB's directly (User Defined types).

The ProSCADA Citect direct interface driver is a front-end / back-end driver, meaning that the driver consists of two parts:

• The back-end server polls the data from the PLC's at configurable intervals.

• The back-end puts the data in a memory cache.

The front-end is a native Citect driver which reads the data from the cache instantly with 0 delay (does not poll the PLC's).

Advantages over the traditional Citect Drivers

This has the following advantages:

1. The Polling of the data is completely de-coupled from the rate at which the clients are requesting it, which means the clients cannot choke up the IO server with requests - no matter how badly the system is configured.

2. With a traditional Citect Driver, all polling is Dynamic & client driven. With this driver each block of data has an individual poll time. This allows each block of data to be optimised to poll as SLOW as is acceptable for that sub-application. This then leaves more resources available for other data that needs to be faster. For example: poll analogs at 5 second interval, setpoints & run-hours at 30 second intervals. Operator perception of speed is associated to digital status and alarm inputs. These can be polled at 0.5 seconds intervals.

3. The data is already available when a client polls it and data is displayed immediately without delay. For example popup screens open instantly with data from the cache.

4. The back-end polls raw blocks of data from the PLC. The front-end can then request any data type from this one polled block. This results in substantial efficiencies when you have many mixed data types in close address proximity. For example: Siemens Instance DB's (User Defined types) like the PID loop DB's are very complicated structures containing floats, words & bits. The Citect S7NT driver would generate a poll for each data type whereas this driver would read the information in one network poll block of bytes to be stored in the cache, the Front end driver then processes a Citect Driver request For each datatype from the same cached data.

5. Communications can be configured and debugged outside Citect. Data can be read from the same cache using a simple OPC client before or while Citect is running.

Advantages over the Siemens Softnet Solutions

This section refers to the Siemens Ethernet back-end. To setup Siemens Simatic Net on a PC and to test the communication can be very tedious. Multiple IO servers have to be used to communicate to more than 20 PLC effectively.

The ProSCADA driver will take 5 minutes to install and run a test with OPC (An Example Citect project is supplied OPC is not used with CiTect). The driver works with any standard 10MB, 100MB or 1GB Ethernet card. To date more than 50 PLCs on a single system have been tested with one standard 100Mb card. More Ethernet cards can be used to communications to PLCs, however there are no real performance or reliability gains. The driver works equally well sharing Citect, Windows workgroups, & Siemens ISO thru 1 Ethernet card. A good Ethernet switch handles different link speeds & network node isolation.

Performance: Siemens has marketing propaganda scaring people into buying their expensive cards with graphs showing performance bottlenecks at the PC card. Our experience is different. The PLC's are the bottleneck & the total Ethernet bandwidth used by the Scada PC Ethernet card is < 5% typically. This driver maximises the communication to all the PLC's on your network by implementing a multithreaded parallel polling strategy. This driver supports up to 64 PLC's on one Network. It has been proven on a system with 50 PLC's & 80 000 IO.
