Hi, I am working on a machine recently shipped from China. The PLC is an "S7-226 CN" connected to a TP178B touch screen. I discovered that this Siemens hardware is intended for sale & use in China only. All the part numbers correspond to the usual ones except that all Chinese made gear ends with an '8', hence TP178. When I try and download the program block to the PLC, it aborts saying that the instruction mnemonics are invalid. When I change the language on Micro/WIN to Chinese, it works ! I would've thought the PLC would actually care about the language settings? Any ideas anyone ?
