Hello everyone, this is my first time asking for help here, so please bear with any problem my english or lack of experience can cause.
i have a little problem with the serial reading on RSLogix 5000.
My project basically is a microcontroller connected by serial to my PLC L32E, i first send from the micro 3 strings of 17 chars, after those i send an array of the first three in one longer string, with the first 3 ones there is no problem, but after sending the last one, it adds characters of $$ to the end of the line, sometimes in the middle of the string appears $$$ or even $00, which cause the buffer to stay with a query of 2, and that misplace the next lines incoming, that extra characters appears at random, and since i am using ARD it is causing a lot of problems.
i read the manual of the rslogix about configuring the serial connection, the instruction help of the commands and still cant figure out what is the problem.
