Overview
Modicon M580 automation
platform
I/O architectures
Modicon M580 type of architecture
Note: These architectures can be combined with each other
Architectures with local racks (main rack and expansion racks) Architecture with local racks (main rack and expansion racks) Architecture with racks in remote drops
Hardwired Distributed peripherals over eldbuses Distributed peripherals and I/O over Ethernet Remote over Ethernet
Compact topology with devices hardwired
on local I/O
Compact topology with devices distributed
over eldbuses
Distributed devices and I/O topology over Ethernet Remote I/O + Remote functions (including eldbus master)
