Hex to ASCII

[AngBaj]

Hi there,

How to do HEX conversion to ASCII in Rockwell software? In Siemens there is HTA instruction. Any advice's?

I have RFID scanner I need to display scanned code on the HMI, but read value need conversions.

Has anyone got Add on instruction for that?


Thank you in advance

I'm going to assume you are only converting numbers, unless you are spelling words that only contain A through F, is this correct?

If so, take the SINT form of your Hex value and ADD 48. Then MOV this value into your new String. Example: MyString.DATA[0], next one in MyString.DATA[1], etc... Make sure to set the length of your string MyString.LEN.

If the task is to take a value stored as an integer in the Rockwell Logix PLC, and convert it to a string in that PLC, you may find this you-tube video helpful:

There is also an example in the Rockwell sample code, but it is harder to find than the video linked above.
