1. Series 31

Communication with Ethernet Board Ethernet version is realized by the socket communication (TCP/IP communication) with FANUC Ethernet Board, or FANUC Fast Ethernet Board. And in case of Series 16i/18i/21i-MODEL B and Series 30i/31i/32i-MODEL A, Ethernet version can communicate with CNC side by the 'Embedded Ethernet function'.

Before using, refer to the necessary manual, and confirm the following items. Settings of TCP/IP in your personal computer side. Settings of the Ethernet Board and Embedded Ethernet function in the CNC side. Physical network connection between your personal computer and the CNC. The number of the application software(clients) that can connect to one CNC at the same time depends on the type of Ethernet interface as follows. Fast Ethernet Board Ethernet Board Note 1) Embedded Ethernet Clients at the same time maximum 20 maximum 10 maximum 5 PCs at the same time maximum 20 maximum 10 1 (recommended) Note 1) Maximum 3, in case of 6561/03, or 6561/04(for Series 16i/18i/21i, Power Mate i). Series 30i/31i/32i-A does not support the Ethernet board.

See the manual 'APPENDIX D RESTRICTIONS' in 'FANUC Ethernet Board/DATA SERVER Board OPERATOR'S MANUAL (B-63354EN)', 'FANUC FAST Ethernet Board/FAST DATA SERVER OPERATOR'S MANUAL (B-63644EN)' for details. The communication using the Embedded Ethernet is processed on the CNC CPU. This means that the running condition of CNC may affect the communication performance of the Embedded Ethernet, and conversely, the communication condition of the Embedded Ethernet may affect the process of CNC. The Embedded Ethernet function is processed at lower priority than the process such as the automatic operation, or each axis process at the manual operation.

Therefore, during the automatic operation, or in case that the CNC is configured so as to have many controlled axes, the communication speed may be slow. The other way, the Embedded Ethernet function is processed at higher priority than the process such as screen display process of CNC, C-language executor(except the high level task), macro executor(except the execution macro). Therefore, the performance of these processes may go down by doing the communication of the Embedded Ethernet. The following Ethernet applications cannot be used because the adequate performance may not be acquired by the above reasons. CNC Screen Display Function. Application for the DNC operation. In case that the Embedded Ethernet is connected to the Intranet that uses many broadcast data, it may take a long time to process the broadcast data.

Series 31

So, it may affect the performance of the process such as screen display of CNC. Modified: 2018-06-10.

Number of path: 10 - 15 path Max. Total number of control axes: 96 axes (72 feed axes, 24 spindles) / 10 path 72 axes (56 feed axes, 16 spindles) / 15 path Max.

Number of simultaneous control axes: 24 axes The big capability of this model helps to realize an advanced multi axis machine tool. Thanks to a number of control axes, various machining processes can be executed at the same time. Its 5-axis machining function can achieve the machining of complex shape. It has the flexibility to control various types of machine tools.
