i have a problem as my device net DRM21 being used with CJ1M CPU13-ETN is indicating "F1" on its 7-Seg display - means Bus OFF Detected as per the manual. The manual says the Correction is check the following: • Matching master and slave baud rates • Proper cable lengths (trunk and branch lines) • Broken or loose cables • Installation of terminators at both ends of the trunk line • Excessive noise The only thing i wonder is about the DeviceNet cables. But there are many cables used for this network and they're covered closely. anybody who can help me.
