Resolving the block configuration errors
Table 34 lists the parameters of all the blocks that can cause the status bit of Block Configuration
Error to be set in their respective BLOCK_ERR parameters. The following table provides the
initial values and the valid range for the parameters.
ATTENTION
Block configuration errors can only be cleared if the function block is being
executed (running). One way of determining block execution is by doing a
series of two or three reads of the BLOCK_TEST parameter and confirming
that the first byte of the parameter is incrementing. This works, if the execute
rate is fast relative to the speed of reading BLOCK_TEST. A very slowly
executing block may not appear to execute as the parameters are updated
only when the block executes.
Table 34: Resolving block configuration errors
Parameter Initial Value Valid Range Corrective Action
ALERT_KEY 0 non-zero Initial Value is a configuration error.
Set value to non-zero number.
SIMULATE 1 (disabled) 1-2 (disabled -enabled) Set value in valid range.
PV_FTIME 0 0-200 Set value to valid range.
ALARM_HYS 0.5 (%) 0-50 (%) Set value to valid range.
HI_HI_PRI,
HI_PRI,
LO_LO_PRI,
LO_PRI
0 0-15 Set value to valid range.
HI_HI_LIM,
HI_LIM
+INF +INF or within
OUT_SCALE range
Set value to valid range.
LO_LIM,
LO_LO_LIM
-INF -INF or within
OUT_SCALE range
Set value to valid range.
BYPASS 0 1:OFF, 2:ON Initial value is a configuration error.
Set value in valid range.
SHED_OPT 0 1-8 see Shed Options in
the FF specs.)
Initial value is a configuration error.
Set value in valid range.
HI_HI_LIM
HI_LIM
+INF
+INF
PV_SCALE, +INF Values must be set in rank order. For
example, LO_LIM > LO_LO_LIM but <
HI_LIM etc.
LO_LIM
LO_LO_LIM
-INF
-INF
PV_SCALE, -INF Values must be set in rank order.
OUT_HI_LIM

+/- 10%
Verify that OUT_HI_LIM > OUT_LO_LIM.

Verify that SP_HI_LIM > SP_LO_LIM.
