6. l e PSC crashed when recording large models The database parameter max_allowed_packet increased to 100M e PSC showed warning PRJ W 032 for parallel connector when using 2 VLD elements between the same nodes This is suppressed now for VLD as it is intended for the standard case e PSC showed error INT E 137 NULL IDatabase after simulation when not recording to database e Check for positive connector length did not work as expected e PSC crashed some times when using RAM limit of more than 2047MB because of the B value exceeds the int limit e GUI Bugfix Selection Editor Got error message Table pscresults sim doesn t exist if database schema pscresults does not exist e PSC Viewer Bugfix Tracks are now drawn in the same order as in the project file e Analysis Tool Analysis handles now also emf footer logo pictures Output for lines leakage current Now using default unit mA m may be changed back to A km or A m in preset if necessary Output for lines Added columns to datasheet for pantograph voltage that show course ID engine index and timestep of engine that caused the minimum or maximum voltage at the particular location Output for energy overview Added possibility to output mechanical energy of the vehicles traction braking braking achieved through regeneration This has to be enabled in preset by setting the attribute use of the corresponding row item to true under TableTypes Energy
