cpu226cn to cpu226 conversion

hi all..
i have cpu226CN,,, i want to change my this china cpu with orignal CPU226.,, is this possible to do so??
Furthermore,, CPU226cn is connected with em231-em232 and em222 and siemens hmi ,,, if i changed cpu226cn,,do i also need to reprogrammed all modules and hmi??or i can use existing programme??

thanks in advance,,!

Hi Dear,
There is no difference in 226 and 226CN. CN is Siemens copy. All software for 226 work on 226CN. Do you have backup of 226CN cpu? Just download 226cn backup to 226 CPU through Micro win software. All other modules remain as same position. No need to change or reprogram of HMI.

using microwin 4.0 sp9,, to communicate with Cpu226cn,,

i changed languange to chinese,, but it shows following screen.

kindly respond!! :-(
