MC−PNC (controller)
I/O data l Configurable up to max. 5760 bytes input
l Configurable up to max. 5760 bytes output
Data transport l Ethernet frames
Communication l PROFINET IO−RT
– cyclic and acyclic
Acyclic data l Read, write, record: max. 1 kbyte/request
l Alarms
Functions l Cyclic process data
l Buffering host−controlled data exchange of cyclic
data
l Minimum cycle time: 1 ms
l Different cycle times are configurable for different
devices
l Max. 32 devices can be configured
l DCP
l Context management via CL−RPC
l One buffer is available per device for diagnostic
data
Special features l No support for
– RT over UDP
– Multicast communication
– DHCP
l Only one IOCR1 per IO device is possible, IOCR data
length: 1024 bytes
l Max. number of the connectable IO devices
decreases to 25 when cycle times lower than 4 ms
are used.
l NameOfStation of the IO controller cannot be set
via the DCP Set NameOfStation service but only by
the configuration during the start
