Host Engineering was started in early 1992 in a partnership with Koyo Electronics Ltd. in Japan. Koyo chartered Host Engineering to create a PLC programming package in coordination with the 1994 launch of PLCDirect by Koyo (now who would be selling the Koyo-produced PLC products. The result of this effort was DirectSOFT, the first Windows™ based micro-PLC programming package.

From those humble beginnings, Host Engineering has 'enlarged its tent' to cover control and communications products including enhanced PLC programming software, data servers, human-machine interface products, PC-based control, Ethernet, Profibus, Ethernet/IP, and motion interfaces to encoders and drives.
