Husam Posts: 101 Rating: (11)	Hello I am a student working a project using WinCC 6, CPU224XP.. I have written a Ladder code that reads and writes data to the serial port of the CPU. THe problem is i have followed the example ladder provided in the manual that initializes the blocks and the port by SM0.1. The problem is that i can read and write to the port only once, and cannot read again.. can somebody help? it is urgent.. i need a continous read/write to the same serial port of the CPU..
