Thank you for your interest. I use 6 serial ports.

Thanks for your reply.
However, each address of ModBusMaster_Local_3 you modified must have a different Slave ID.

HMI (Touch Screen) operates in Modbus Master Mode.

Thank You.

I cannot edit components.
Please help me how to fix the component and I will fix it.
Is there no way?

Please help me.
Thank you.

I posted my project.

Could I apply your advice and test it over the weekend?

Thank you.

Does the Modbus master of FC10 support 8bit Data, Parity None, and 2Bit Stop bit?
If FC10 supports it, please tell me how.

Thank you.

I am posting my project abbreviated here.
Please review carefully and point out my mistakes.

And please refer to the link as well.

I am developing equipment for industrial use. I can't use C language, so I use FC10 to develop equipment. The developed equipment was installed today, but was rejected by the customer. The reason is that the Modbus/RTU Master reads data from the device too slowly, so the data is not read properly an...

Good morning.!

I am trying to read data from a Modbus device.
In FC10, only the baud rate can be changed.
However, the device supports even, odd parity, or 2-bit stop bits.
How can I read Modbus data from a device?

Thank you.

Can you please advise how to speed up the MCU? It's so hard. Modbus Master still operates too slowly.

Thank you

I tried many things. However, MCU speed is still poor and sometimes unreadable.
Perhaps timing is the issue.

Still no way. I'm looking for another way.

Please Help me.

Thank you.
