5 Configuration

By changing the following variables of the structure g_sercansII.config during the first IEC cycle some configuration settings of the card can be influenced:

6 Detect and Solve Problems

A: The system seems to be unable to communicate with the drives:

A1: The following variables might give you a hint what causes the problem:

-check Global_Variables_SercansII -> g_SercansII.strDiagnosis

-check Global_Variables_SercansII -> g_SercansII.sb.scr.psY31SysErrorSercans

-check Drive_Basic global variable g_strBootupError

A2: If there is no error information:

-check if interrupts occur. Therefore force Global_Variables_SercansII -> g_sercansII_bDebug to TRUE and watch Global_Variables_SercansII -> g_sercansII_udiSercansInterrupts. This number should be increased with every Sercos cycle.

A3: only CoDeSys SP RTE:

-check whether you have installed the driver RTIOdrvBRCSerc under RT Service->System- >IOdrivers

A4: If interrupts occur:

-check whether your task is triggered by the “external event” <name of AxisGroup>.bSync or g_bSercosInterrupt. If no interrupts occur, then there is a problem with the IRQs on your system

B:The drives start up, but seem to be non-synchronized:

B1: task configuration

-check whether your task is triggered by the “external event” <name of AxisGroup>.bSync or g_bSercosInterrupt. If no interrupts occur, then there is a problem with the IRQs on your system

B2: only CoDeSys SP RTE:

-check whether you have installed the driver RTIOdrvBRCSerc under RT Service->System- >IOdrivers

B3: interrupt timing

-force Global_Variables_SercansII -> bDebug to TRUE and watch Global_Variables_SercansII -> g_SercansII_Times.uiMinDiff and g_SercansII_Times.uiMaxDiff. They should be about the cycle time of the AxisGroup.
