 Function Block - Returns a list of bad EtherCAT connections.

Inputs

Input

Data Type

Range

Unit

Default

Description

Enable

BOOL

FALSE, TRUE

N/A

No default

Read the communication errors on the rising edge.

Connection

ECATCommErr_ref

See the ECATCommErr_ref Structure table.

N = 0 to 2 times the number of EtherCAT devices.

N/A

No default

Array of bad connections.

The safe size for the list is:

[2 * (number of devices) - 1].

Outputs

Data Type

Range

Unit

Description

Done

BOOL

FALSE, TRUE

N/A

Indicates whether this function block has completed without error.

Error

BOOL

FALSE, TRUE

N/A

Indicates whether this function block has completed with error.

ErrorID

DINT

No range

N/A

The function call error result, if Error is TRUE.

  • See the Error Codes table.
  • Upon success, Error is set to 0 (zero).

ConnectionCount

UINT

No range

N/A

The number of bad connections.

Valid indices in the Connection array range from 0 (zero) to ConnectionCount -1 (assuming ConnectionCount != 0).

Remarks

If EtherCAT network communication is shutdown, the failed connections are based on information that was taken at the time the network was shutdown.

Error Codes

Value Dec (hex)

Error Code

Description

0

ECERR_OK

The SDO call succeeded.

1000 (0x3E8)

ECERR_DEVICE_ACTION_IS_INVALID

The requested Device Action is invalid.

1003 (0x3EB)

ECERR_DEVICE_ACTION_MINIMUM_ONE_NODE_REQD

1004 (0x3EC)

ECERR_DEVICE_ACTION_MINIMUM_ONE_DC_NODE_REQD

A minimum of one Distributed clock capable device must be present in the EtherCAT network.

107 = 0x6B

ECERR_INVALID_ARRAY_SIZE

The size of the connections is too small.

  • When the array size is smaller than the number of bad connections:
    • The array is filled with the data to the size of the array.
    • The error ECERR_INVALID_ARRAY_SIZE is set.
  • In this scenario, the output ConnectionCount is set to the size of the array and it is smaller than the number of actual bad connections.
