TwinCAT IO and FCxxxx

TwinCAT IO with FC310x, FC510x and FC520x

TwinCAT IO contains the device drivers and the configuration software (TwinCAT System Manager) for the FC310x, FC510x and FC520x PC cards under Windows NT, 2000 and XP.
The FcIoApi DLL provides the interfaces for freely selectable Windows applications for accessing the process data of these PC cards.

Regarding the configuration of the fieldbus via the TwinCAT System Manager please refer to the descriptions of the following PC cards: FC310x, FC510x, and FC520x, which also contain detailed descriptions of the respective diagnostics interfaces.

In addition to the fieldbus configuration, an IO task for re-triggering the associated fieldbus card has to be set up in the TwinCAT System Manager. The cycle time of the IO task corresponds to the fieldbus cycle time. To this end, at least one fieldbus device variable (FC310x, FC510x or FC520x) has to be linked with an IO task variable.
