Red Lion to V1000 via Modbus

[mikulen]

I have been tasked with developing control of a set of 64 Yaskawa V1000's using a Red Lion G310 HMI on Modbus. I am totally unfamiliar with all three of these. I know I need to learn them but I was wondering if someone who has a program that they could send me a copy of as a reference? I have worked almost exclusively with AB and Siemens and I am having a difficult time finding enough slow time to learn this scheme. Specifically, I do not see how to setup the tags in the HMI to send a speed reference to the inverter. I read through some of the manuals that came with the Crimson 3.0 software but I cannot find were modbus tags are addressed.

Hello
The V1000 Technical Manual (#SIEP C710606 18A) has a section on Modbus. On page 386 of my manual starts all the registers now these are all in hex. So 0001H would be 4001 or 40001 decimal.

Now 0001H is a bit value you will need to be able to input from the HMI. I have done it with EZ-Touch and Proface HMIs mostly with PLCs. 0002H (4002 or 40002dec)is your Frequency Reference.

H5-01 thru H5-12 are the drive paarameters for setting the drives communication protocol (you will need to set these to the same as the HMI).
NOTE: Each drive must have a unique address I start with 1,2,3...

Now you will have to set the parameters to be able to control (write) to the drive b1-01 & b1-02.

Now if you want to just monitor the drive at first then the H5-_ _ parameters are all you need to change (this is what I start off with first).

This should get you started.

Thanks Tom,

That is a great start. But I am not seeing how to setup the write from the HMI. It is a packet of 4 words to each inverter (if I am reading the manual correctly) that I need to send to modify the frequency preset.

Post what you have done so far and we can help. If you haven't started a configuration, do so - you will find it is easy to do what you want to do.

Hi,

I had a quick look at the V1000 and it has RS485 Modbus as default and Modbus TCP as option.
Do note that there is a limitation on RS485 of max 32 devices, but I would never have that many devices - as the update time will be in the range of seconds..
I believe that Schneider recommends up to 8 slaves on RS485 Modbus...

So for your sake, I hope that you intend on running it on Modbus TCP....

My 2 cents

I'm still not seeing how to send a data packet from the HMI.

From the Yaskawa Tech Manual:
Message Content
In MEMOBUS/Modbus communications, the master sends commands to the slave, and the slave responds. The message format is configured for both sending and receiving as shown below, and the length of data packets depends on the command (function) content.
SLAVE ADDRESS
FUNCTION CODE
DATA
ERROR CHECK

Remove the Gateway block, Configure the correct comm settings for the RS-485 port, Configure PLC1 with the correct Device ID.

Then create Read/Write Tags and address them to PLC1 using the correct Modbus registers.

I don't have the register list for your drive, but once you figure this out and get the comm settings right, you will be able to write from your G310 display.

Again, remove the Gateway block completely. You don't need anything below the PLC1 because the tags (on a display) take care of the comms.

Hi
If you are using Serial Modbus RTU
Under the navigation pane click the communication button,now click on the RS-485 Comms Port enter the port settings. Under driver selection try Yaskawa Series 7 Invertiers if I remember the V1000 and Generation 7 (F-7...) the regesters were close to the same.
Right click on RS-485 Comms Port and add a couple another devices.

In the navigation pane click on Data Tags, click New to add a tag. Now you should see tag 1 in the main window under Source change internal to PLC1 this will be the drive with address 1.
Now a window should of poped up here is where you will select the parameter written to or scroll down and use Direct Address.

Thanks Guys. Here's what I have so far. I really could not have gotten this far so quickly without all your help.

I doubt that you need separate read and write tags. I noticed that you are using the same address for both. Why not just have a read/write tag?

 

[mikulen]

Here's what I have to start. The reads and writes work. I just need to fill in the tags and copy my indicators.
