Abstract: The present invention makes it possible to reduce a load associated with transfer of parameters. A control system is equipped with first and second controllers connected to a network, and a drive apparatus for driving a motor in accordance with an instruction from the first controller. The drive apparatus includes a memory that stores a safety program for implementing a safety function, and a parameter group referenced by this program.

Abstract: A precast concrete silo complex and a method of constructing it, in which quarter-cylindrical precast concrete members, constituting unit members, are each provided with a pair of radially protruding couplings near both the ends of the member, and the unit members are arranged to form unit cylinders. The unit cylinders are arranged lengthwise and crosswise, with the couplings facing the couplings of adjacent unit cylinders for defining a coupling space between each two adjacent unit cylinders. Horizontal clamp rods extend through the coupling spaces between the end portions of the unit members and between the couplings, and concrete is provided in the coupling spaces. The horizontal clamp rods are tensioned to clamp the end portions of the unit members and the couplings, to give prestress to the concrete, thereby combining the adjacent unit cylinders and solidifying the unit cylinders arranged lengthwise and crosswise.
