Posted 18 May 2023 Hi everyone, I wonder if there are registers contains Lot No of C200H or CJ1M CPU. It is like A311, A310 of CP1H. Thanks Share this post Link to post Share on other sites
Posted 22 May 2023 I have looked but can not find a adress for them but you can check it with CX programmer go online with the PLC then open PLC IO right click the CPU you get a menu , then select Unit Manufacturing information and there is the lot number . you can also see it on the sticker on the side of the CPU but its kind a hard to see if its installed . be warned the manual states before 2003 models support can be non existend on some CPU models Share this post Link to post Share on other sites
