A packer module with selective control and fluid bypass can be interactive with other packer modules in a system for isolating and evaluating. The packer module includes a motor section, a conversion section, a control section, a sealing member, and an isolated flow path section. The control section includes a ramp sleeve cooperative with the sealing member to set a retracted configuration, an initial sealed configuration, and an isolated sealed configuration of the sealing member. The isolated flow path section includes an isolated flow path channel. The isolated flow path channel can only be opened with the sealing member in the isolated sealed configuration so that a zone formed by the packer module can be isolated and evaluated. Measuring and detecting instruments along the different flow paths through packer module evaluate the fluid properties of the bypass fluids and isolated fluids through the different flow paths.
