If you are working with our AKB-P model, by default they output the data in hexadecimal. Then, in your PLC, you need to setup a Bit Field Distribution to parse out the data to get the decimal value you are looking for. Below are examples of a 16 bit distribution as well as a 20 bit distribution. Depending on the value you are trying to get, you may need to use more or less bits.
