BLOCK_ERR parameter bits

Several SIS function blocks have the BLOCK_ERR parameter. The following table shows the BLOCK_ERR bits that can be set in SIS blocks (each block's BLOCK_ERR parameter contains a subset of the bits). The table also shows the bit position for each error and how to access the bits from DeltaV Operate.
