Hello Jack_TGI; The different model numbers are explained in the screenshot below, the image is taken from Appendix H of the S7-200 System manual: https://support.industry.siemens.com/tf/us/en/posts/s7-200-cn/71606/?page=0&pageSize=10 The Simatic S7-200 family has been offered worldwide since around 1990. For markting purposes Siemens decided to offer a Chinese version of the S7-200, the S7-200CN, with very smilar part numbers, but slight differences such as the Regional settings of the Windows OS needed to be set to Chinese, and different sets of approval certificates. As you can see in the following discussion, (pay special attention to the entries from Ganes10 and pfuser) the main difference between the standard and CN expansion modules is the missing UL standard approval; they still carry the CE certification though. If thisis not a problem for your project, you can use the 6ES7231-7PB22-0XA8 as a diect replacemen for the 6ES7231-7PB22-0XA), without any problem. Hope this helps, |
