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.
Claims5
1:
- A relay device in a manufacturing system provided with a host computer configured to perform control via communication based on a SECS/GEM protocol, and multiple devices configured to perform communication via a non-SECS/GEM protocol that is not based on SECS/GEM, the relay device comprising:
- protocol converting processing configured for performing conversion between the SECS/GEM protocol and the non-SECS/GEM protocol when data is communicated between the host computer and each of the multiple devices;
- and
- transfer processing configured for setting multiple communication ports corresponding to each of the multiple devices, receiving transmission data sent from the host computer to each of the multiple devices via the communication port corresponding to the device that is a transmission destination for the transmission data, and transferring the data of after the protocol converting processing to a device in accordance with the transmission port.
1 more element
2:
- The relay device according to claim 1, wherein
- the transmission destination is changed in accordance with at least one of a function or a stream representing contents of the transmission data set based on standards of the SECS/GEM protocol set inside the transmission data sent from the host computer.
3:
- The relay device according to claim 2, wherein
- the multiple devices include a work machine and a management device configured to manage control data for controlling the work machine, and in a case in which a number of at least one of the stream or the function is a number related to the control data, the management device is set as the transmission destination.
4:
- A manufacturing system comprising:
- the relay device according to claim 1;
- 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,
- wherein
- the multiple devices include
- a work device, and
- a management device configured to manage control data for controlling the work machine, and
- the host computer, before starting work by controlling the work machine using the control data, performs control data acquisition process for acquiring control data from the management device.
6 more elements
5:
- The manufacturing system according to claim 4, wherein
- the host computer, during the control data acquisition processing, in a case in which multiple versions corresponding to the control data to be acquired are saved in the management device, performs notifying processing for notifying a fact that the multiple versions are saved.
