Hi, I am new to GE Fanuc LM90-30 and this morning I was asked to upload PLC program from an online-running GE Fanuc LM90-30 series with the CPU 363. The PLC program running online uses proficy machine edition however the laptop I'm using does not have Proficy Machine Edition installed, therefore a trial programme was downloaded from the internet and installed in the laptop. Test was done offline with a new blank CPU363 and it was successful. I then tried to hook up to the Running PLC but failed and messages saying Timeout error. I check all connections and they are okay. RUN LED was on as seen on the online running processor and the key slot was horizontal. I retried by creating a new project, right click on the target and select the type of LM90-30 then go online to verify connection but it still fail with communication error. With the offline CPU363, I can connect and see the PLC with RUN LED off and key slot in horizontal.. Need your assistance, thank you.
