Parameter
Description
Limitations
The size of the bus configuration file is limited by the size of the RAM
Disk (1 Mbyte)
The usable (minimum) cycle time depends on the number of used IO
Devices, the number of used input and output data.
RT over UDP not supported
Multicast communication not supported
DHCP is not supported (neither for PROFINET IO Controller nor for
IO-Devices)
Only one IOCR per IO-Device per direction
One instance of DeviceAccess AR can be used at the same time only
MRPD is not supported
Planning of IRT is not done by the PROFINET IO Controller protocol
stack
Sync Slave is not supported
One fragmented acyclic services can be used at the same time only
Multiple MRP Managers are not supported
One DCP Service can be used in parallel only
Multiple Sync Masters are not supported
