question for web browser

[yang]

I am new for iX developer, but I have many years experience in C#. Is it possible to use web browser in iX developer?

[mark.monroe]

There is a web browser that is available on some of the HMI units that run iX Developer. The web browser has limited functionality however. It does not run Javascript or other standard web browser plugins like flash.

I am using T4A, so it supports web browser?

also I have a question for modbus.

We have one device A as Modbus gateway. It has serial port and ethernet. I try to connect HMI with that device through Ethernet, it works. But I can't use this connection to access device B connected to device A through serial port. is it possible to get access to the device B from HMI? If possible, how I can setup?

[mark.monroe]

No the T4A does not support the web browser.

You can set the Modbus Master Controller driver in the HMI to use serial. You can also have multiple Modbus Master controllers in the HMI, one can be set to use Ethernet, the other can be set to use serial.

Thank you for your response.

For modbus connection, I have device A(modbus gateway with ethernet port and serial port), device B(modbus serial port), so device A is connected to device B. At last I connect HMI to device A through ethernet port. So If I want to connect HMI to device B, how I can do it? Based on your reply, it seems I only can connect HMI to device B through serial port right?

I would suggest you contact the vendor of the modbus gateway. The HMI should be able to communicate through the gateway to modbus device B. There is nothing on the HMI that you need to set to communicate though a modbus gateway.

thank you for your response, currently,

device A is able to communicate device B and also I can use modbus test software on pc to communicate device B via ethernet port on device A. But on T4A, I choose modbus master driver in modicon and If device IP is 192.168.1.105 and device addr. 250, and device B's addr. is 5, how do I set in controller settings on HMI

Under the modbus master driver in iX Developer there are stations. You can type in what node you want to use.

Thank you for your response.

I notice one thing from my modbus test tools. the device B needs the first byte is high, I only see your modbus master driver only can change 32-word order (big endian and little endian), but it can n't change the byte order within one word. right? my serial device only read the first byte high value

[mark.monroe]

Yes you are correct. The 32-bit word mapping Big or Little endian is for 32 bit data sent over the line.
