We are excited to inform you about the release of KPA EtherCAT Master 2 for Linux x64 version 2.7.1310.0.
Since version 2.7.604.0, this latest version brings the following improvements designed to offer you an enhanced user experience.
- KPA Master Redundancy software solution
From now on MDK2 for generic Linux x64 supports software solution for KPA Master Redundancy.
This solution does not require some specific HW module and only a regular Ethernet switch is used for connection Master and the bus. To switch from Secondary to Primary mode the software fast switch is used.
The following changes were made:- Added the samples 55_MasterRedundancy and 56_DynamicStringDemo demonstrating how to work with the Master Redundancy feature.
- Renamed the INI parameter master.secondary.timeoutbase to master.secondary.timeout.
- Removed the INI parameter master.secondary.timeoutfactor and related usage in source.
- Reviewed the description of KPA Master Redundancy in MDK Manual (updated the chapter Master Redundancy, added error codes description in Troubleshooting).
- Extension of the dmkpa library
In order to ensure backward compatibility with Master 1, the following functions have been moved to the dmkpa library:- KPASyncCreate – сreates a synchronization object to synchronize with Master cycle.
- KPASyncReset – resets a synchronization object.
- KPASyncWait – waits for the event on a synchronization object.
- KPASyncDestroy – destroys a synchronization object.
Note that if you have used these functions in Master versions earlier than 2.7, you will need to recompile the dmkpa library to use these functions in the latest version.
