With lean automation, it is not recommended to make full use of the specified limits with regard to the maximum number of stations
per Manager and the maximum number of I/Os per RIO. The following points should be taken into account:
The load on the RIO Manager increases with the rising number of RIO stations. This has an impact on the overall ap-
plication in the RIO Manager.
If there is a large number of RIOs, a sufficiently large amount of PCD media must be reserved on the Manager for the
data transfer.
With a rising number of RIO stations, the build and download process in PG5 is lengthened accordingly. Likewise, the
start-up behavior of the Manager or the entire RIO network is proportionately longer.
Recommendations:
20 Smart RIOs per Manager is a sensible configuration for efficient and problem-free operation, and simple com-
missioning and support.
The Smart RIOs do not have a battery. In the event of an interruption to the power supply, all the data in the RAM memory (registers,
flags, DBs/text) will be lost. Data and parameters that are to remain must either be transferred by the Manager or stored in the RIO’s
flash file system. If this is not possible, the use of a normal controller in place of a Smart RIO is recommended. The user programs are
stored in the flash memory of the RIOs and are retained in the event of an interruption to the power supply.
