System Limits


4 PROFINET Controller modules per RX3i CPU, connected to the same network or to
separate networks.

128 IO-Devices on the PROFINET network.

8 IO-Controllers per network

64 IO-Devices per PROFINET Controller

128 IO-Devices per network, spread across a maximum of 8 IO-Controllers

63/64/130 total devices per PROFINET network, depending on the topology:
For a network using ring topology, the maximum number of devices is 64 – consisting of
o
the PROFINET Controller plus up to 63 IO-Devices. If the ring uses Media Redundancy
Protocol, this means one Media Redundancy Manager and up to 63 clients.
For a network using star topology, the maximum number of devices is 65 – consisting of
o
the PROFINET Controller plus up to 64 IO-Devices.
o
For a network using line topology with two PROFINET Controllers, the maximum number
of devices is 130 (2 PROFINET Controllers plus 2 x 64 devices).

4 PROFINET Controllers per RX3i CPU node

128 IO-Devices per RX3i CPU Node, spread across up to 4 PROFINET Controllers

128 Kbytes of combined input and output memory per PROFINET Controller

Machine Edition Project Maximum Limits

With the above limits, the maximum number of PROFINET IO-Controllers and IO-Devices in a single
Proficy Machine Edition project is:

16 PROFINET IO Networks in a Proficy Machine Edition project

32 Proficy Machine Edition targets per Proficy Machine Edition project

128 IO-Controllers (32 RX3i CPU targets × 4 IO-Controllers per RX3i CPU Node)

2048 IO-Devices (16 PROFINET IO networks × 128 IO-Devices per network)
Total: 2176 Devices (not including backplanes, power supplies, IO modules, etc).
