7 segment LED driving

Hello,

How can I drive a 7 segment LED with an S7-300.Is there any hit or tip to be able to program a LED.I want LED to show 4-20 ma output value with 2 digit.Do you think is there a ready function in s7-300.

Thanks.

How are the 7-segment LEDs connected to the outputs? If the display interface is BCD then you can use the ITB instruction which converts an integer to BCD and then output the bit pattern to the digital outputs directly.

Hans, you can use FC93 SEG from TI-S7 converting blocks section of Standard Library.
