To date more than 50 PLCs on a single system haveД«een tested with one standard 100Mb card. The driver works with any standard 10MB,ДЎ00MB or 1GB Ethernet card.

Minutes to install and run a test with OPC (An Example Citect project is Multiple IO servers have to be used toД¬ommunicate to more than 20 PLC effectively. To setup Siemens Simatic Net on a PC and to test theД¬ommunication can be very tedious. Data can be readДЇrom the same cache using a simple OPC client before or while Citect is running.ДЄdvantages over the Siemens Softnet Solutions The Citect S7NT driver would generate a poll for eachДata type whereas this driver would read the information in one network pollД«lock of bytes to be stored in the cache, the Front end driver then processes aД¬itect Driver request For each datatype from the same cached data.Д¬ommunications can be configured and debugged outside Citect. For example: Siemens Instance DB's (UserДefined types) like the PID loop DB's are very complicated structures containingДЇloats, words & bits. This results in substantial efficiencies when you have many mixed data The front-end can then request any data type from this one polledД«lock. For example popup screens openДЇrom the PLC. The data is already available when a client polls it andДata is displayed immediately without delay. Is associated to digital status and alarm inputs. Setpoints & run-hours at 30 second intervals. For example: poll analogs at 5 second interval, This then leaves more resources available for otherДata that needs to be faster. This allows each block of data to be optimised to poll as SLOW as is acceptableДЇor that sub-application. With this driver each block of data has an individual poll time. With a traditional Citect Driver, all polling is Dynamic &Д¬lient driven. The rate at which the clients are requesting it, which means the clients cannotД¬hoke up the IO server with requests - no matter how badly the system is The Polling of the data is completely de-coupled from

Advantages over the traditional Citect Drivers back-end driver, meaning that the driver consists of two parts:Д«ack-end server polls the data from the PLC's at configurable intervals.Д«ack-end puts the data in a memory cache.Дriver which reads the data from the cache instantly with 0 delay (does not poll The ProSCADA Citect direct interface driver is a front-end

Particularly if the user attempted to poll large configurations of FunctionД«lock instance DB's directly (User Defined types). CitectДЄlso needed a way to optimise the way the SCADA communicates to the PLCs,Д«ecause it was too easy to build setups that overwhelmed the S7NT driver. Simatic Net has a lot of limitations on the number of PLCs it canД¬onnect to and also the performance of the Siemens API has been an issue.
