Good morning Fiixers, I hope everyone is doing wellWe are wondering if anyone has ever had issues with adding to many devices to their PLC network. Earlier this week, we attempted to add 4 additional devices to our PLC network. We are using an Allen Bradly 1769-L35 PLC to run roughly 32 ethernet connected devices, like Allen Bradley 1734-AENTR remote I/O and PowerFlex VFS’s.We attempted to add 4 more devices to the network,( All IP’s were pinged before adding the devices ) and the network bricked, it would not allow COMs between the RsLogix 5000 or our Maple HMI Easy Builder software on our computers. Once we remove the devices from ethernet network, and reset the 1769-L35 PLC, ( Dropping out one whole half of the plant ) we were able to establish connectivity again. We are operating under the assumption that we exceeded the amount of ethernet devices that are able to run on the Allen Bradly 1769-L35. We do have a call in with support to confirm this assumption, but are wondering it an
Good morning Fiixers, We are using Allen Bradley PowerFlex 525 throughout the plant, as you may know the lead time on new VFD’s is currently weeks out. We are wondering if, the PowerFlex power module from a 523 is compatible and supported with a Powerflex 525 HIM module. If this works, then we could simply order the PowerFlex 523’s and change out the HIM module to the PowerFlex 525. Thank you
