Modbus TCP Slave

[BenR]

Hello,

In your project options please can you turn off the Auto clear watchdog setting. The watchdog isn't running so these are a load of instructions that aren't required.

Also I would highly recommend disabling the Low Voltage Programming setting unless you are specifically using it. This can cause a stack of issues. e.g. freezing, self erase etc.

If these don't help then you could also try running the chip at a lower frequency and see if that resolves the problem. As a test maybe try 16MHz - OSCFRQ = 0x05; Remember to also update the frequency in the project options.

I will try it tomorrow morning .
Thank you

I adjusted the options as you instructed.
I tried changing the clock in various ways.
However, the result is as above. It doesn't work.

When will it be fixed?

[seokgi]

I tested various PIC MCUs, but not all of them work.

I don't think this is my fault.

Please fix it quickly.

Thank you.

ModbusTCP Slave still does not work.
Please help me.
Thank you.

problem

Modbus Master: FC10 Simulator, Modbus Poll
Modbus slave: PIC18F67K40, PIC24FJ512GA606

1. When retrieving data, up to 8 data are operated stably in FC10, and only 1 data is operated stably in Modbus Poll.
More than 10 will not work.
2. When importing data, the return value is
Occasionally repeats 0,1. (FC10)
Repeat read error, write error. (Modbus Poll)
If 255 is returned, the slave device is hung up. After resetting the slave device, it restarts successfully.
Sometimes I get 255 and it works fine after a while.
Sometimes it stops after about 10 minutes.

Even if I test the above by changing various options, I get the same results.

Please Help me!
Thank you.
