Step7-200

Hello guys
I have been working on a problem with Siemens step7-200 CPU 226-CN,
It was burnt out and I couldn't found the these Chinese version of the PLC,So I bought the original version, I contacted the manufacturer and they gave me a copy of the software , but now I have troubles downloading the software because the software has BGN_ITIME, CAL_ITIME , they're incompatible with the cpu...
Anyway to solve the problem.. or to get around them using original timers..

I haven't used either of the instructions, so don't ask me for more information.

A copy of the Siemens Manual:
https://cache.industry.siemens.com/dl/files/582/1109582/att_22063/v1/s7200_system_manual_en-US.pdf

Page 203 for BGN_ITIME.

Page 78 you could use ReadRTC and store it, Read RTC again and subtract one from the other.

Or use a millisecond timer T0 or T32 or T64 or T96, obviously make sure they aren't used anywhere else.

What are the part numbers of the CPU 226-CN, and the "non-CN" CPU?

Incompatible with the CPU or with the current CPU firmware version?
Maybe its a matter of updating the CPU FW to the latest compatible with your hardware.

The S7-200 wasn't like the S7-1200, you couldn't upgrade firmware.
