BLOCK_ERR Block Configuration
Error
The parameter "CHANNEL"
has not been assigned a valid
value (1 ... 4). Assign valid value (see section
6.3).
The function block was not
assigned a schedule. Include the function block in a
function block application and
load this in the device.
The target mode of the block is
"RCas" and "SHED_OPT" is at
"undefined". Assign valid value, e. g. "Normal
Schedule - Normal Return".
Input Failure The status of PV_D is "bad". • Check the value fed back by the
transducer block.
• Check diagnosis message of
transducer block.
Output Failure There is an error in the trans-
ducer block which affects the
output. Check diagnosis message of
transducer block (section 7.3).
Simulate Simulation for this block is acti-
vated. See section 5.4.2 and appendix
B.
Local Override The reference value has been
overwritten by the safety value
via the bus due to as missing
reference value specification. • Check communication.
• Check device which specifies
the reference value.
Out of Service The block is in "Out of Service"
mode. • Select suitable target mode.
• Check block configuration error.
Problem Cause Elimination
Cross
reference
The function block does not leave
the "Out of Service" mode There is a block configura-
tion error which is signalled
in "BLOCK_ERR". See "Diagnosis
messages". See "Diagnosis
messages".
The resource block is in
"Out of Service" mode. Set resource block
into "AUTO" mode. See also section
7.2.
The value of OUT_D is displayed in
READBACK_D instead of the value
fed back by the transducer block The option "readback sup-
ported" in parameter
"FEATURES_SEL" of the
resource block is not set. Set option.
The value of OUT_D is not trans-
ferred to the transducer block Simulation is ON. Switch OFF simula-
tion.
Simulation cannot be activated The simulation switch is not
switched ON. Check in resource
block whether the
simulation switch is
ON; switch ON, if
necessary. See also section
5.4.2.
Parameters cannot be written Write protection activated. Deactivate write
protection. See section
5.4.2 and
appendix C.
