Serial Output

[JoeB7774 0]

Hello.  I am new to programming with a Modicon 340.  I would like a serial output to a printer (or an LCD screen) (eg) an input is registered and I would like an output to display the results of the input.  Does the Modicon 340 support this?  I have the P3420302 module which appears to have a serial connection (along with ethernet).  If someone could point me in the right direction I would greatly appreciate it.

Hi, just use PRINT_CHAR block  to send any data via serial interface.

You will find example in the description of this block.

Also to add to quant you must specify in the port config if you are talking rs232 or rs485 etc before communicating to the printer. Normally this will be rs232 and as Quant suggested use the Print_Char function block
