TOYOPUC PC3J/PC2J FL/ET-net-5

FL/ET-net-5 is a module with the function of “FL-net" and "Ethernet". The FL-net mode and the Ethernet mode are switched with the dip switch in front of the module. FL-net is the best for the data link between a high-speed,/large capacity control equipment. Ethernet is the best for the communication by the command response with the personal computer. Please select left contents about details. Ethernet　is a registered trademark of Xerox.

1. The interconnection with the product for other companies FL-net is possible by a standard network for next generation FA.
2. A high-speed (10Mbps) and large capacity (2048 points +2048 words) can be communicated. (When CPU module is used since PC3JL-CPU, 2048 points + 8192words can be communicated. (one word = two bytes))
3. Participation/secession to the FL-net communication is always possible because of the management of the token of Mastarres (transmission right) in each node. (Even when the trouble occurs in the power supply determination and the communication cable and telecommunications equipment, etc. , keep communicating between nodes which can be communicated. )
4. Participation/secession to the FL-net communication is always possible because of the management of the token of Mastarres (transmission right) in each node. (Even when the trouble occurs in the power supply determination and the communication cable and telecommunications equipment, etc. , keep communicating between nodes which can be communicated. )

N:N data link communication

In N:N communication method, the transmission data of a certain node becomes receive data in another node, and common "Common memory" data in the entire network is shared.

1:N data link communication

In 1:N communication method, The transmission data of the bureau which corresponds to master bureau (*1) is received in slave bureau (*1) and the transmission data from the slave bureau is received only in the master bureau. The data link of the slave bureau is not done. There is merit by which the data link area in the slave bureau can be saved when using (*O) with Andon etc. ＊In 1:N data link method, though communicated without the distinction of the master bureau and the slave bureau because the network of FL-net is Masterless, the bureau which receives the data of all bureaux is virtually expressed , "master". The bureau which communicates only with "master" is expressed, "slave".

1. It is the best for the communication with the personal computer etc. corresponding to Ethernet which is the world standard of the communication between computers.
2. Ethernet can have eight independent ports, and communicate simultaneously with eight terminal bureaux or less.。
3. The communication cable and telecommunications equipment for Ethernet widely marketed can be used. (The telecommunications equipments such as the transceiver, repeaters, and HUB must use the one for the IEEE802.3 standard. )

Computer link method

The response is returned to the command transmitted by the personal computer etc. The command which can be used I/O register word reading/writing I/O register byte reading/writing I/O register bit reading/writing I/O register multi point word reading/writing I/O register multi point byte reading/writing I/O register multi point bit reading/writing Data extension word reading/writing(for PC3J) Data extension byte reading/writing(for PC3J) Data extension bit reading/writing(for PC3J) Data extension multi point reading/writing(for PC3J) etc. Besides this, the command can be forwarded to other CPU modules connected with HPC-LINK, ME-NET, and FL-net, and "Relay command" be used.

File memory method

The data of the I/O register is sent and received by processing the sequence program. The reception side transmits "Reception confirmation" by which data is normally acknowledged to the transmission of the file memory.
