Abstract
A programmable logic controller capable of maintaining waterproofness or dustproofness includes a base unit with a substrate, a base case housing the substrate, and at least one holding part to hold a connection unit which is one of a plurality of module units. The connection unit includes a module-side connector, an engagement mechanism to be detachably engaged with the at least one holding part, and a module case with a fitting tenon to be engaged with the base case. The programmable logic controller includes an elastic member to apply a force in a first direction, which is a direction in which the connection unit moves away from the base unit, thereby pressing the engagement mechanism of the connection unit against the at least one holding part of the base unit, and a sealing member to seal a gap between the base case and the fitting tenon of the module case.
