  1. Slow serial communication

    seven posted a topic in Mitsubishi

    I have to receive data via serial port from a device and I am using a FX5U with RS232 port.  The only baud rate which seems to work is 2400, which is very low in my opinion. I have tested the serial comm on the device with a PC, same cable and it works flawlessly at 57600 baud rate. The FX5U and device serial settings are similar. Any ideea what can cause the low speed?

    Cable is double shielded and 3m length. With the PC I got the right data at any baud rate, but with PLC I got corrupted data or no data at baud rates higher than 2400.
  3. I have the following array received from the RS232 port: RD_data[0]=H0020 RD_data[1]=H0030 RD_data[2]=H0030 RD_data[3]=H0030 RD_data[4]=H0031 RD_data[5]=H0035 RD_data[6]=H002E RD_data[7]=H0032 RD_data[8]=H0036 which means " 00015.26" how do I convert it to the real number 15.26 in FX5U PLC? SOLUTION: I used BTOW to set the data for EVAL instruction
