Scadapack serial ports use modbus rtu serial protocol. Telepace is a ladder programming package for Scadapack units made by control microsystems. You do not state which Allen Bradley plc you are using.
I assume one of the RSlogix 5, or packages will work to program it. If you have an ifix software package, it runs a driver to get data from the plc. If it is connected to a serial port on the Scadpack, I would assume the ifix MBR driver serial modbus rtu is being used. In order for you to connect any device to a serial connection on the Allen Bradley, Scadapack or ifix workstation, it will have to talk the specific protocol native to that device. And either you device or the plc will need to be programmed to transfer data.
Thank you Rod for your reply. Thanks for conforming my questions. I hope you understand my question - simply saying the PLC should first send data to my device then my device should do some task and send back the data to the PLC and then the PLC should send that data to the modem. Could anyone please help me in this matter.
Thanking You -Sandeep. Regardless of the PLC, there are essentially 3 ways to communicate with it: 1. Issues with 1: Most of the protocols are fairly complex. Either way, you are probably best off searching for IP intelluctual property which supports the protocol you are interested in and using it as "canned" FPGA code, if it exists.
There are also sometimes generic "boards" that you can mount your circuitry to. So expect to do some sort of level shifting to be able to interface. Issues with 3: This is fairly easy to accomplish and often the simplest to be able to support. This tends to look like the issues with 1 above. Thank You very much for your reply. It uses Telepace Ladder Logic Editor to configure the ports and communications, and also handles the program to talk with it slave PLC's with the help of ladder logic program written for slave devices which follows poll type of communication i.
But now, i am confused with 1 what changes should i do in the ladder logic program so that it communicates with my FPGA device 2 the Telepace software configuration settings should be changed to detect my FPGA and send it data. The default configuration of the serial port is the one which i require, so is that when i connect my FPGA device does the PLC automotically detect my device or should I configure the serial port again to the required parameters.
These commands will tell me how to write the code to handle the data when it sends to my FPGA device. Hands-on training will help you put theory to practice giving you the skills and confidence you need to be a SCADAPack user.
Introduction to features in the Telepace Studio Programming software including ladder logic programing, step by step instructions to build a ladder logic program in Telepace Studio. Introduction to features in the Realflo flow computer configuration software, learn in detail how the flow computer operates and understand flow computer regulations.
Step by step instructions to build and simulate a flow computer in Realflo, utilizing the Gas, Liquid and Water flow computer functionality. Introduction to the SCADASuite software, learn how to build a measurement compliant Welltesting application utilizing the programming previously created in Realflo. Included in the course:. Configuration registers are used to modify the configuration of an application on an RTU.
Control registers are used to make run time changes, like enabling a manual override, or changing a set point. Status registers are used to view the status of an application via Modbus. The Exclude Configuration Registers option allows you to generate an export without configuration registers. Take care when using this option, because if configuration is actually enabled, then the export won't be complete and register contention may occur.
See the Applications and Modbus section for details. Sample Modbus Register Export. Export to Telepace. Use this button to export the application's Modbus register map into a format that can be imported into Schneider Electric's Telepace Studio software.
Telepace Studio requires that tag names are unique and less than 32 characters long. Because of this, some long names may be truncated or have numeric characters appended.
Each tag has an application specific prefix prepended to the tag name. This identifies what type of application that the tag belongs to, and also creates a unique name for a tag across all applications. Prefixes are listed in the table below. Function Generator.
Well Test. Plunger Lift. The Exclude Configuration Registers option can be used to create an export that doesn't include any of the registers that are used for configuration groups and parameters. This is useful in the case where the application is configured to not allow configuration via Modbus registers.
See the Applications and Modbus section for more details. Export Glossary. Use this button to export an application glossary in CSV format. The glossary contains all the configuration, control and status parameters for teh application along with the description of how to use the parameter that is either shown in the configuration screens are on the test tab. This makes it easier to understand what each parameter does without having to move through multiple screens.
The export uses ClearSCADA server and client ViewX automation to create points, configure the points for minimum, maximum and other settings, create mimics and display points on said mimics. Once the export is complete the only remaining step is to connect the automatically created Outstation object to a Channel object.
Select the Create Mimics option if you want the export to create and configure mimics. This feature uses ViewX automation, which is not officially not supported by Schneider Electric. Unchecking this option will create and configure groups and points, but won't use any ViewX automation. Uncheck this option if you see errors during the export. This export is really a proof of concept, and isn't much use for real systems. Contact Gen7 Systems if you're interested in this functionality.
