Function Block DI

Diagnosis messages
Parameter
BLOCK_ERR
Miscellaneous
The function block does not leave the
„Out of Service" mode
The value of OUT_D is not the same
as the PFC sensor values measured
by the transducer blocks.
The value of OUT_D is not refreshed
or shows strange behavior.
Simulation cannot be activated.
Parameters cannot be written.
Subject to reasonable modifications due to technical advances.

Error detection and problem solutions
Cause
A value other than 5 has
been assigned to the
parameter „CHANNEL".
No schedule was assig-
ned to the function block.
The transducer blocks
report a status of "Bad -
Device Failure". This
might be caused by a
hardware error.
Simulation is active for
this block.
The block is in „Out of
Service" mode.
Cause
There is a block configura-
tion error which is signalled
in "BLOCK_ERR".
The resource block is in
"Out of Service" mode.
Simulation is active.
I/O-Option "Invert" is
active.
The function block is in
"Man" mode.
The parameter
"PV_FTIME" does not
equal 0.
The simulation switch is not
switched ON
Write protection activated.
Elimination of Error
Elimination
Set „CHANNEL" to 5.
Integrate the function block
into a function block applica-
tion and load this into the
device.
Send the device to Pep-
perl+Fuchs for repair.
See chapter 5.4.2 and
appendix B.
• Select suitable target mo-
de.
• Check Block Configuration
Error.
Elimination
See "Diagnosis
messages".
Set resource block
into "AUTO" mode.
Switch off simula-
tion.
Switch off "Invert"
option.
Set function block to
"Auto" mode.
Set parameter value
"PV_FTIME" to 0.
Check in resource
block whether the
simulation switch is
ON; switch ON, if
necessary.
Deactivate write
protection.
