EtherCAT Init Block DC Error Values

The Simulink® Real-Time™ EtherCAT Init block returns the following EtherCAT® distributed clock (DC) error values related to the master shift controller and the bus shift controller.

Error Value

Description

1 (0x1)

Initialization function not called or not successful

2 (0x2)

Controller error — synchronization out of limit

Master shift: error 2, Maximum controller error exceeded

Bus shift: error 2, Maximum controller error exceeded

3 (0x3)

Not enough memory

4 (0x4)

Hardware layer — (BSP) invalid

5 (0x5)

Hardware layer — error modifying the timer

6 (0x6)

Hardware layer — timer is not running

7 (0x7)

Hardware layer — function is called on wrong CPU

8 (0x8)

Invalid DC synchronization period length

9 (0x9)

Error DCM Controller SetVal is too small

10 (0xA)

Error DCM Controller — Drift between local timer and ref clock too high

11 (0xB)

ERROR: Error DCM Controller - Bus cycle time (dwBusCycleTimeUsec) doesn't match real cycle

27 (0x1B)

DC controller not ready

Master shift: error 27, DC controller not ready
