Product Description XI/ON - Eaton Automation

XI/ON: Gateways for Modbus TCP 7 Guidelines for Station Planning
Further limitations can be placed on the maximum possible number
of XI/ON modules by the use of the Power Feeding modules
XN-PF-24VDC-D or XN-PF-120/230VAC-D; these being used either
for creating potential groups or by insufficient field supply.
Attention
Ensure that a sufficient number of Power Feeding or Bus Refreshing
modules are used if the system is extended to its maximum.
Note
If the system limits are exceeded, the software I/O-ASSISTANT generates
an error message when the user activates the "Station →
Verify" command.
