[Tweet](https://twitter.com/share) ### Version 3.0.0 of the Opto 22 Library Package for the CODESYS Development System is now available. [![blog.opto22.comhubfscodesys-Jul-18-2022-05-30-16-65-PM](https://blog.opto22.com/hs-fs/hubfs/social-suggested-images/blog.opto22.comhubfscodesys-Jul-18-2022-05-30-16-65-PM.png?width=200&height=200&name=blog.opto22.comhubfscodesys-Jul-18-2022-05-30-16-65-PM.png)](https://www.opto22.com/support/resources-tools/downloads/opto-22-library-package-for-codesys-development-sy)For all of you taking advantage of the CODESYS programming environment available for *groov* EPIC, you'll want to hear about this week's [version 3.0.0](https://www.opto22.com/support/resources-tools/downloads/opto-22-library-package-for-codesys-development-sy) release of the Opto 22 CODESYS library package. With CODESYS, you can program *groov* EPIC for industrial control and monitoring using any familiar IEC 61131-3 compliant language. Version 3.0.0 brings you a new collection of OptoMMP client function blocks you can use to access any area of an Opto 22 device's memory map. The IEC 61131-3 standard includes several languages, some of which you may already know. [*groov*](https://www.opto22.com/products/groov-epic-system)[ EPIC](https://www.opto22.com/products/groov-epic-system) supports all IEC 61131-3 compliant languages, including: - Function Block Diagram (FBD) - Structured Text (ST) - Sequential Function Charts (SFC) - Ladder Diagram (LD) The OptoMMP memory map provides a programming interface to an Opto 22 device's I/O and other features. The new function blocks are:  - MmpClient - MmpClientReadBlock - MmpClientWriteBlock - MmpClientReadQuad - MmpClientWriteUDINT - MmpClientWriteReal #### What are Opto's engineers most excited about for this release? The most significant update is the ability to get quality and status data from I/O modules and their channels. Now you can parameterize all configuration, quality, and status info into your CODESYS control logic. You could use these function blocks to save I/O configuration data within your CODESYS project, or even configure I/O via your HMI. Using these functions also lets you leverage the OptoMMP Scratch Pad area and integrate many legacy Opto 22 systems into your projects. [![GET CODESYS 3.0.0](https://hubspot-no-cache-na2-prod.s3.amazonaws.com/cta/default/439485/1389dab7-04d6-4216-8c8a-689d8e68f3c1.png)](https://hubspot-cta-redirect-na2-prod.s3.amazonaws.com/cta/redirect/439485/1389dab7-04d6-4216-8c8a-689d8e68f3c1) For the details on this latest 3.0.0 library package, please see the[release notes](https://documents.opto22.com/RM_Library_Package_for_CODESYS.pdf). If you're just getting started with CODESYS on groov EPIC, the CODESYS Development System is available at no charge from the CODESYS Store at [https://store.codesys.com](https://store.codesys.com/).
