Resolving the block configuration errors

Table 30 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.
