Description

NETID

T_AmsNetId

The network address of the TwinCAT computer on which the ADS command is to be executed can be specified here. For the local computer an empty string may be specified.

DEVICEID

UDINT

The DeviceId is used to specify the SERCOS master whose communication phase is to be set. The device IDs are specified by the TwinCAT system during the hardware configuration.

PHASE

BOOL

The communication phase in the SERCOS ring that is to be set.

SET

BOOL

The function block is enabled by a positive edge at this input.

TMOUT

TIME

Specifies the time-out period that must not be exceeded when the command is executed.

Description

BUSY

BOOL

When the function block is enabled, this output is set and remains set until a feedback is received.

ERR

BOOL

If an error should occur during the transfer of the command, then this output is set once the BUSY output was reset.

ERRID
