You can set individual sizes of the 4 Modbus data type databases. It is also very easy to modify the register / data point values. You may need some way of talking RS485 / RS422 from the PC though as I expect that the interface you are going ti use from the PLC / CP will be ...
The solution is to open the port, then wait a bit (my program waits for 1 second). After 1 second, you can read/write and everything will work. Here is a portion of code I used, adapted from some other examples i found on the web for serial communication via codesys and raspberry ...
I need to receive data from two interfaces (RS232 and RS485) on my IoT. But since it only has one serial port, I would like to add a serial to usb adapter to be able to read both. I would like to know if this is possible and how it should be done.Not
UART READ BYTES ERROR (IDFGH-1839)#4048 Closed What if you change this You should then get data event and break event As for the mod, the newer uart.c has changed so much I can't figure out where to put the mod now... uart.c at line 850 now is: ...
Since the RS-422 four-wire interface uses separate transmit and receive channels, there is no need to control the data direction. Any necessary signal exchange between devices can be done in software mode (XON/XOFF handshake) or hardware mode (a pair of separate ...
