EMERALT - a short introduction
EMERALT is a powerful operation control software designed to realize everything from consolidated control functions to complex, shared control systems with high-speed feedback control. EMERALT enables you to design flexible and modular solutions for anything from a simple control system to a control network involving several devices.
EMERALT software works on all IBM-compatible PCs using the operating system Windows2000.
The operating speed of EMERALT software depends on the performance of the PCs involved. Thanks to its high flexibility, EMERALT software supports the configuration of almost all types of devices:
64 analog inputs (max. 512,16 bit resolution)
4 analog outputs (max. 64, 16 bit resolution)
144 digital inputs and outputs (max. 576)
16 full duplex serial RS-232C ports (max. 64)
IEEE-488.2 interface, transfer rate 1MB/s
EMERALT software consists of several different components. The main component, called EMERALT Kernel, represents the services control point for all connected equipment. The EMERALT Kernel is a command line application, responsible for the communication among the connected devices through the relevant drivers.
EMERALT Command Line
The EMERALT Kernel is a command line application that can be used to interact with the EMERALT Kernel, i.e. send relevant instructions or commands to the EMERALT Kernel.
The programming language EMERALL is another important part of the EMERALT software.
EMERALL is composed of a pre-compiler and an interpreter. The C-like programming language is of very solid and simple structure, but at the same time it includes sophisticated regulation elements to run extensive control sequences. These enable the user to set up a program for frequently used or long-running procedures.
The EMERALL programming language is able to combine several different language elements into one. It allows to program command blocks in a way that they can be run several times in a row (loop construction). You may also, among others, inquire the current condition and react to the relevant returned values.
This programming language enables the user to operate the equipment any way required while having full control of the sequence of events.
EMERALL consists of the following language components:
Supervision of execution time
Realization of parallel processes
Synchronization of processes (program components that are being executed in parallel)
Communication of processes (program components that are being executed in parallel)
Based on C language
For a detailed description of the EMERALL syntax as well as instructions on the use of the compiler and the interpreter, please refer to our manual.
EMERALT GUI is the graphical user interface of the EMERALT Kernel. It visualizes the connected devices as well as their current condition. Each condition has been assigned a different color, so it can easily be identified whether the device is still working in the assigned area or whether an error has occurred. The EMERALT GUI includes a message window listing all commands executed and the relevant return values from the EMERALT Kernel. This enables the user to supervise whether or not the EMERALT Kernel has executed a command correctly.
All programs written with the internal EMERALL language can be compiled, started and terminated in a designated program window. All compiler messages will be displayed in the message window, so any possible syntax or compilation error can be detected immediately.
