EC_ReadAxisInfo
| Function block | EC_ReadAxisInfo | ||
|---|---|---|---|
| Reads an axis' state through Service Data Object (SDO). | |||
| VAR_IN_OUT | |||
| V | AxisIn | AXIS_REF | Reference to an axis. |
| VAR_INPUT | |||
| V | Enable | BOOL | Gets the value of the parameter continuously while enabled. |
| VAR_OUTPUT | |||
| V | Valid | BOOL | TRUE if a valid set of outputs is available. |
| V | Error | BOOL | Signals that an error has occurred within the function block. |
| V | ErrorID | MC_Error | Error identification. |
| V | VendorId | UDINT | Vendor ID of the device. |
| V | ProductCode | UDINT | Product code of the device. |
| V | RevisionNumber | UDINT | Revision number of the device. |
| V | SerialNumber | UDINT | Serial number of the device. |
| V | SlaveId | UINT | The slave index. This index value is automatically assigned by the KINGSTAR master when the EtherCAT network starts, based on the physical connection order. The first device connected directly to the master is assigned Index 0, followed by Index 1, Index 2, and so on. These indexes remain consistent within the slave array even if devices are added, removed, or reconnected. Please refer to the use cases in HotConnect, Repair, and Restart for more details. |
| V | PhysAddress | UINT | The physical address of a device, used by the EtherCAT master to access the device. It is configured by the master during startup. Values are 1001 + slave index. |
| V | AliasAddress | UINT |
AliasAddress (or station alias) is used to identify multiple identical devices with the same Vendor ID and Product code. It is a software defined value, stored in the device's EEPROM, and can be written using tools or by the EtherCAT master (WriteSlaveAlias). You can set up AliasAddress for devices in specific roles, such as X, Y, and Z axes. When the AliasAddress is changed, the device must be power cycled for the change to take effect. IMPORTANT: The alias address is intended to be a software defined value, but some devices map it to a hardware DIP switch. In such cases, the value should never be changed in software, as it may trigger a device error. Please check your device's user manual for the station alias information before using it. |
| V | State | EC_State | EtherCAT state of the device. |
| V | CycleTime | UDINT | Cycle time for a slave. If the slaves on the KINGSTAR Fieldbus network can't catch up the cycle time of the master, KINGSTAR auto-configuration will slow down their cycle time based on their capabilities. |
| V | Resolution | UDINT | Encoder resolution set in the device, if it is a drive. |
| V | Name | STRING | Name of the device. |
