CoDeSys has powerful program editors where toolbar icons, menu items are automatically adjusted as per IEC language selected. Sample for CFC programming displays freely placed blocks rather than a grid. Off-line Simulation CoDeSys has an off-line simulation facility.
This is very vital utility for an application program developer, as one can develop complete program logic independent of PLC. This feature helps the developer to complete the application program development on or before scheduled time. On-line Functionality CoDeSys has on-line program monitoring and on-line program modifications features. This makes it suitable for continuous process application, where program modifications without process interrupt may be required.
Watch and Receipt window facilitates to monitor multiple variables, simultaneously from multiple program organization units POUs. It has command entry line cum result display window, which is like a combo-box.
It has smart history of latest executed commands, which Sample for using PLC browser, a handy and quick tool for developer displays it without repetition of command. The concurrent and continual data logging is possible by devising advanced programming techniques in Microsoft Excel spreadsheet. These values in Excel spreadsheet sheet cells get overwritten, on very next pre-defined time interval in CoDeSys project.
One needs to use symbolic variables. This sampling rate is user settable. The sampled values are stored in internal trace buffer. If this ring buffer gets full, data purging takes place i. Trace configuration facilitates user to set various parameters for sample trace. The trace configuration settings can be saved to a file, which can be reloaded with option load trace feature. Similarly, sampled data can be saved in text file. The detailed parameters description for trace configuration is as explained here.
Other features like stretch, compress, Y Scaling Typical example of sampled temperature and pressure, in a process application allows user to adjust the trace window for the requisite visibility. Enabled show grid option makes grid as well as X-Y axis values to be visible. Parameter Description Trigger Variable This terminates sampling activity. Trigger ON. This decides percentage of measured values, which will be recorded Trigger Position before Trigger On event occurs.
Positive Triggering occurs after the rising edge of Boolean Negative Triggering occurs after the falling edge of Boolean Triggering Edge Both Triggering occurs both at, rising and falling edge of Boolean None Triggering does not occur at all.
Number Minimum 32 of Samples Maximum Similarly the saved text file for sampled data can be readily transported to Microsoft Excel, where user can take further analytical and database storage actions. This allows user to design application specific screens, using various GUI elements or visualisation elements like: rectangles, rounded rectangles, ellipse, polygon, polyline, curves, BMP images, buttons with limited events and the other visualisation itself.
It also facilitates a user to have a regular configuration of these elements. These configuration parameters vary as per visualisation element. This makes Visualisation as very handy tool for viewing the dynamically changing data in textual or even graphical form. User can simulate a mimic or even a process using these visualisation elements.
Also user can force PLC outputs from this interactive screen. In comparison with other front end tools Visual Basic, Power Builder, Oracle Forms , this has limited capacity and features. It is strongly recommended to use this tool for test and monitoring purpose rather than control action. Thus, a function block can call other function block or function and cannot call program.
Class Class defines the scope of the variable viz. Global elements are accessible to all the POUs in a project. CoDeSys compiler forcibly insists data type declaration for an every variable used in the project, except PLC addresses.
Thus these variables can be referred in other POUs of the same project. Value of the variable can be given along with the call, in calling POU.
Value of these variables are returned back at the calling POU. These variables can be used further, in the POU. Value of such a variable is always passed by reference rather than value. These variables are not applicable to the function. The CPU is capable of handling various data types. The CPU can handle various instructions like: l Boolean instructions l String handling instructions compare, search, left, l Timer instructions right etc. Physical Layer Physical layer is comprised of several elements viz.
Maximum supported distance is 1 KM. The RS connected station is called as Half Duplex as it either receives or transmits the signal. In some cases, TX needs to put to tri-state when receiving starts. Nexgen x series having serial 2'nd and 3'rd port, are convertible from RS to RS and vice versa.
Protocol Protocol is synonymous to language as both the devices should communicate and understand the same language. It is predefined sequence of codes for data exchange. By using protocol converter, two devices having un-identical protocols can communicate.
A protocol is command and response having, header, body and a trailer. Header is indicative of a new message begin, body is comprised of command number, data and any other information need to communicate. Trailer has error checking checksum and end of transmission character. Protocols work independent of physical layer. Messung Protocols are specific to Messung products and are not open for its use. Communication parameters are Baud rate, Data bits, Parity bits and Number of stop bits.
Typically one byte frame consumes 11 bits and at bits per seconds, it takes 1ms per byte frame. Nexgen has two buffers viz. RX buffer and TX buffer which simultaneously handle transmission and reception, functions independently and in parallel to PLC scan.
It delivers same throughput, facilitates variety of communication speeds and exerts complete control on communication scheme. User can create only single instance of the block and can be attached to any port.
ModeSel can have values as 0, 1 or greater than 1. Its 0 value stands for on-demand or manual updation, only once but in overriding mode. Its value 1 stands for cyclic execution but only once per network scan. When ModeSel has value greater than 1, it can be grouped and gets executed along with cyclic. This can be attached to any of the Nexgen communication port. Freqrol Inverter FB This block facilitates a user to connect 31 freqrol Inverters and user need not know Inverter interface protocol.
It reflects fast changes to set point changes. Communication speed is settable to 9. The base plate is available with or without expansion connector to offer economic solution. It is available with or without power supply connection facility. In multi-rack system, additional power supplies can be connected into expansion plates.

The module converts thermocouple input mV values No. Temperature Resolution 0. Isolation Channel to Channel Nil Channel to internal circuit 1. Of Output Channels 2 Isolated, 12 Bit resolution. The module provides 2 isolated channels with 12 bit No.
Output type is Voltage only. Conversion Time 20 m S. Isolation Channel to Channel 1. Accuracy 0. ADC Resolution The Multifunction Input module provides mix of inputs with programmable filter time, pulse catch input, interrupt input and counters with programmable 16 bit operational mode. Programmable filter 10ms and up counter is the default configuration.
In such case, the inputs are not available as normal inputs. The pulse having minimum m sec ON time can be detected. Upon detection of interrupt signal, the operating system of PLC branches to predefined interrupt task. The counters can be programmed for external reset using normal inputs. These inputs Discrete can be selected in groups of 4. Programmable Delay Pulse catch 2 m sec. These are accumulating type programmable reset 4 counters. The counter has external direction input and programmable reset 2 10 Khz input.
This count is available in predefined register. Equipped with programmable display and keys, HMIs allow easy operation and monitoring in the production area.
HMIs display operational and fault messages, enable machine specific parameters to be monitored and modified in suitable format. HMI keeps the operator fully informed of the current status of operations at all times.
