Look at the Help on the Protocol block - it allows you to create a "stream" variable which will map the contents of the serial port to a block of MI registers. You can compare these registers to another block of registers containing your "exact value" and set a bit.
Hi - we have added this to the feature request list. I don't have a time line for development right now, but I certainly can see the need @SoCold, thanks for raising the issue!
(and thanks to @Joe Tauser for tagging me )
In info mode -> serial -> monitor I can read card numbers in ASCII but I have no idea how to get to that data on HMI. How can I get to it in ladder program? I would like to create a program that read card numbers and if card number = some exact number then it would set some memory bit to 1 for few seconds. Please help.
Serial port properties are: PCOM, RS232, 9600, 8, n, 1, 9984 us, card numbers are shown on Rx.
