Parameter Descriptions:
CALL FC24 // Call diagnostic function
IBDB := DB20 // INTERBUS data block
ACTIVATE := I4.0 // Acknowledgment button
AUTO_START := M100.0 // Automatic restart
RUN := M100.1 // Message: INTERBUS active
PF := M100.2 // PF (Peripheral fault)
BUS_QUALITY := M100.3 // Determined error
density exceeded
DETECTION := M100.4 // Diagnostic routine is
active
BUSY_STATE := M100.5 // FC IB_DIAG display active
RET := M100.6 // Result bit
START_UP := M100.7 // INTERBUS start after PLC
startup (OB100)
IBDB Global INTERBUS data block (in the
example: DB 20).
ACTIVATE This parameter is controlled by a button
which must be connected externally and
acknowledges an existing error. After a bus
error, the INTERBUS system is restarted.
The diagnostic display is refreshed in the
event of a peripheral fault.
AUTO_START = 1: If an error occurred, the function of
bit 0 or 2 of the standard function start
register will automatically be activated. If
the error cannot be removed, the function
of bit 0 or 2 will be re-called (see DBW98 in
IBDB) at a certain interval.
= 0: Only the "ACTIVATE" (or START_UP)
parameters enable activation of the
function of bit 0 or 2.
RUN Status message: INTERBUS is active.
= 1: INTERBUS is in RUN
= 0: INTERBUS is in STOP
