Abstract
Provided is a relay device and manufacturing system that relays communication based on SECS/GEM protocol to a manufacturing system using a different communication protocol, and enables integrated management via a SECS/GEM host. Relay device performs protocol conversion between a SECS/GEM protocol and an original protocol that is a non-SECS/GEM protocol, and transfers data transmitted between user host and manufacturer host. Also, relay device performs transfer processing based on a port correspondence database that specifies local IP addresses of manufacturer host and the like and TCP protocol port numbers corresponding to these IP addresses.
Claims20
A system comprising:
- a host computer configured to perform control via communication based on a SECS/GEM protocol;
- multiple devices configured to perform communication via a non-SECS/GEM protocol that is not based on SECS/GEM;
- and:
- a relay device disposed between the host computer and the multiple devices, the relay device including circuitry configured to:
- perform conversion between the SECS/GEM protocol and the non-SECS/GEM protocol when data is communicated between the host computer and at least one of the multiple devices;
- set multiple communication ports, each corresponding to one of the multiple devices;
- receive transmission data that is sent from the host computer to the at least one of the multiple devices and that specifies a communication port corresponding to the at least one of the multiple devices that is a transmission destination for the data;
- and
- transfer the data to the at least one of the multiple devices that is the transmission destination including changing a destination address in accordance with the communication port.
