To Create Modbus Map in ION7650

Hello,

Our client is asking to create a specific Modbus Map with their required Modbus addresses in a way that their RTU reads their Required Registers from ION7650 through it's RS485. I found Modbus Export Module can do this job but I couldn't get it to work. I set Connection to 'Serial Connection 1' and assigned the same ID of ION7650 serial port 1 for 'Slave Addr'. (please find below screenshots for the details of this module). 3 phase voltages linked to source input of Modbus Export module and also a Periodic Timer send a pule to 'WriteNow' every second. I did try to read the values of three voltages (Vll ab, Vll bc, Vll ca) started with address 256 using Modscan but I couldn't read the right values. Modcsan was talking to this serial port 1 of ION7650 BUT it seems my configuration in Designer hasn't changed anything in registers reading through this serial port. the configuration of serial port 1 of ION7650 is as below:

Modbus RTU, 19200 bps, ID:201, Tran Delay: 0.010, 8N1

Modbus Export setup is as below:

Connection: serial connection 1

slave add: 201 (the same as port 1 address)

Reg Addr: 40256

Request type: Multiple

Format: singed 32B

scaling: No

Your helps to get this work is highly appreciated.

Mohsen

Re: To Create Modbus Map in ION7650

Now I understand that you need actually to build a modbus map for the GE D20 RTU inside the ION7650.

This means ION7650 will be the master and the GE will be the slave.

To create such map you need to use a "Modbus Master Map Module" to create the map for the GE device/s, then several "Modbus Master Device modules" for each GE device that you add under the ION7650.

In the ION Reference document, please refer to "Modbus Master Map Module" to see a example of a map for ION6200. Similarly, you can setup one for the GE device.

I hope this clarifies the situation. If more help is needed, please create a technical support case.

Re: To Create Modbus Map in ION7650

Hello Mohsen,

If I understand correctly your application (you're trying to write/send data to the third party RTU), then the only thing you need to change is the ION7650's protocol to Modbus Master (master device) instead of Modbus RTU (slave device).

Re: To Create Modbus Map in ION7650

Hi Victor,

thanks for the response.

Client is requiring their own Modbus map with specific addresses for some parameters (ex. addr 256 for Vll ab Lowbit, addr 257 for Vll ab Highbit). I thought that it is possible using Modbus Export module but not sure.

Thanks,

Mohsen

Re: To Create Modbus Map in ION7650

I think client RTU would be master as it's polling for the data if so ION7650 should be slave (or Modbus RTU). Not sure if this is achievable.

Re: To Create Modbus Map in ION7650

If that's the case, then you need to use Modbus Slave modules to expose data to custom addresses and, as you mentioned, to set the 7650 to Modbus RTU.

However you need to check first the "default data registers available on the ION7550/ION7650" and see what's already mapped to those addresses.

Re: To Create Modbus Map in ION7650

Thanks Victor.

I just sent you our client required Modbus map; could you please have a look and advise if it is achievable.

Thanks
