hi
I have developed a PC Based SCADA Sytem using WINCC Flexible Advance to replace the unrepairable Siemens' OP 270 HMI and saved lots of cost to buy a new + software development cost.
I am having problem in communication. I have two CPU 224XP & 226. the baud rate for both the CPUs are 19.2, PC adress 0, 224XP @ 1 & 226 @ 2. all the setting of com port are same, but I am still facing problem in connection to establish communication.
I am also using a PC adapter of ADAM. I connect as follow:
Red = Data+ (Adam terminal)
Green = Data- (Adam terminal)
using COM 1 at PC & same as on CPU 224XP.
Adam controller's led status shows the I am getting data but when I start run time, there is no communication happening.
so guy help me out, I am running short in time.
Thanks
Nitin
