Hi. I have a problem with MODBUS TCP MASTER. I treid to read HR in range 3027-3037 but I cannot read them. I have modbus slave chanel with offset 0x3037. I checked what I read and it looks like I am reading HR in range 1-10. What I am doing wrong.
hello Use FC3 instead of FC4
codesys is in hex and starts at 0
your other program is set to decimal and maybe starts at 0 or 1, I can't tell.
