Hi, I'm new with PLCs omron and I have a problem when comunicating to the plc, I connect with the plc serial port and when I click the "Auto online" button, everything is just fine, the program uploads to my pc with no conflicts at all, but when I try to go online with another program to download using the "Work online" button the software says that it can't connect and maybe the PLC is bussy, which is not because I can upload the plc program at any time. Please help me I've worked for 2 years with plcs Allen bradley and Siemens. Thank you for your support.
