YASKAWA VIPA SPEED7 - OB 86 - RACK_FLT - Slave Failure; Restart

6.9.6 OB 86 - RACK_FLT - Slave Failure / Restart
The operating system of the CPU calls OB 86 whenever the failure of a slave is detected
(both when entering and outgoing event).
If OB 86 has not been programmed, the CPU changes to the STOP
mode when this type of error is detected.
The OB 86 may be delayed by means of the SFC 41 and re-enabled by the SFC 42.
The following table describes the start information of the OB 86 with default names of the
variables and its data types:
Variable Type Description
OB86_EV_CLASS BYTE Event class and identifiers:
38h: outgoing event
39h: incoming event
OB86_FLT_ID BYTE Error code:
