FB-PLC uses binary code to store and to execute calculations. If want to send the internal PLC data to the
●
external displays such as seven-segment displays, it is more convenient for us to read the result on screen
by converting the BIN data to BCD data. For example, it is more clear for us to read the reading "12"
instead of the binary code "1100."
Converts BIN data of the device specified at S into BCD and writes the result in D when the operation
●
control input "EN" =1 or "EN↑" (
0~9999999), then the error flag FO0 is set to 1 and the old data of D are retained.
