How many ACS880 drives can we communicate with drive composer pro via Ethernet network?
There are 184 Numbers of ACS880 drives in one of the process line. Requirement is to communicated all the ACS880 drives with one drive composer tool. FENA-11 Ethernet adaptor was installed on all the 184 drives and the network configuration as follows.
15 numbers of 16 Channel Ethernet switched were used and 14 drives were connected to each Ethernet switch. All the Ethernet switches were connected each other with Ethernet link. An Ethernet cable was routed to the PC from the 1st Ethernet switch.
Started the Drive composer pro in the PC and added fixed IP for all the 184 drives and tried communicating. I have noticed only 128 drives were communicated. Checked each and every drive communication by pinging individually and found okay.
Is there any limitation with drive composer pro, that only 128 drive can be communicated??
I can advise you to ask ABB Drives support for exact limitation on how many drives could be connected to Drive composer trough FENA-11 module.
Also may be there is a suitable technical solution in your case (not like using of 2 Drive composer's and drives, separated in two segments).
I suppose the connection is based on Modbus TCP/IP.
Looking on your explanation for max. 128 nodes, I could conclude that is the limitation, coming from Modbus TCP/IP.
