Posted 26 Jan 2017 Hello everyone. i use q04udeh cpu and rs-485 qj71c24n-r4 communication module. I try to receive information from external device(2000amp power supply). im not a professional plc guy. On that moment i get MSG_RECV_String[7], and store them in separate buffer from K1B108 to K1B120. i skip one because i do not need that k4B100 , and start from k1B108. I want to show value Voltsx10, but i need some help to do it. when i change value i see numbers from each separate MOV block function, but i can not convert them to decimal.(or i do not know how to do it). When i try BIN command i have error message 4100. Thank you for any suggestions. Share this post Link to post Share on other sites
Posted 31 Jan 2017 If I understand you correctly you get a string value and want to convert that to Decimal. You should use the VAL command instead of BIN. Bin is for converting a decimal value to String. Val converts a string into a Decimal value. You can use the LEN instruction to find out the length of the string.
