Highspeed Link(Ethernet)
The Ethernet High Speed Link program is used when fast communication between CIMON PLCs is needed. This program allows each PLC to send and receive data of 64 stations,
but sending stations are limited to 32 stations. There can be a maximum of 64 words executive data in a station. In order to enjoy the best performance, it should be separated with other networks.
If it works with other networks, its network speed will be significantly reduced.
Registering the HighSpeed Link(E) program
Select [File] -> [New Program] -> [HighSpeed Link(E)] menu.
Enter the Program Name, Program ID and Program Free Space (OnlineEdit Buffer).
Click the [OK] button.
Note: [PLC Link] in [Parameter] does not support High Speed PLC Link to PLC-S.
Only [Ethernet High Speed Link] program in the Communication Configuration supports this function.
Communication modules compatible with [Ethernet High Speed Link] program are as follows:
PLC-S: All CPU modules with Ethernet Option
PLC-S: CM3-SP01EET (Ethernet Expansion module)
CP/XP: CM1-EC10A, CM1-EC10B
Note: CM1-EC01A of CP/XP series is not compatible with Ethernet option of CM2-BP series.
High Speed PLC Link Port
Communication Port Number: UDP/IP 10264
Writing the HighSpeed Link(E) program
An example of using the Ethernet HighSpeed Link program: Communication is established between two modules where #1 PLC-S sends data which increases
by +1 at every second to the device area D11 of #2 PLC-S. Then, the received data will be sent back to the device area D11 of #1 PLC-S.
Likewise, this example includes 32 blocks of internal communication between these two PLC-S modules.
Have two PLC-S modules ready and connected with two programs inside the CICON software.
Write a scan program that increases the data by +1 at every second as shown below.
Below images are two separate Ethernet High Speed Link programs for two PLC-S modules.
Set station numbers (Stn) as 0 and 1 for #1 PLC-S and #2 PLC-S respectively.
Then, click on [Add] button.
Block numbers for #1 PLC-S and #2 PLC-S must be the same in order to communicate. Configure so that TX block number of #1 PLC-S is identical with RX block number of #2 PLC-S as shown above.
The address of the Block Number 0 will travel from Device D10 of #1 PLC-S and send data to D11 of #2 PLC-S as shown above.
In the same way as above, you can add 32 blocks for each #1 PLC-S and #2 PLC-S. When you complete adding blocks, it will look like below image.

TIP: PLC can send and receive a maximum of 64 data blocks while sending blocks are limited to 32. If the number of sending blocks exceeds 32, you will get an error message as shown below.
When you’re done with configurations, download the programs into the #1 and #2 PLC-S respectively and see the communication results.
When you check the communication results, you can use Memory Monitor to see the online status of PLC-S while in RUN mode.
