Posted 8 Nov 2016 Dear All, Hi my name is arum. I am just starting my own project using CS1W-LCB01 and Omron CS1G CPU42 H, and i am using CX process to program the LCB01. The first time i try the LCB, it was doing well, no error occurred. But now, I have some problems here. 1. Internal board error always appear 2.Error 0A0D was detect when i am try to download the program to LCB. Iam using CX server communication driver. Because the problem always occurred, I clear the PLC memory then download again the PLC configuration, and then restart the PLC configuration every time this problem occured After some times, it doing well. 3. But now, I even cant download the program because there always communication timed out Anyone had experience with this case. Please give me some advise. Thank you in advanced.
