Note 1 Even if the operation cycle is synchronized, the order of operations in
function blocks is the operation execution order shown above. So, the
operation order is not necessarily the same as the internal connection order
in the software wiring. For example, the connection is as follows when the
internal connection is analog input block, square root block, PID operation
block, non-linear block and then analog output block:
