B.2 – Large System
B.3 – Very Large System
GFK-2816F
Appendix B. PROFINET IO Performance Examples
This system contained an RXi controller connected in a network bus
configuration to 20 VersaMax PNS modules (IC200PNS001), each
configured for a 16ms PROFINET update rate.
Each PNS contained at least 1 discrete input, discrete output, analog
input, or analog output module.
The IO Loopback measurement was taken using a 16-point output
module (IC200MDL741) owned by one VersaMax PNS, that was
then tied to the 16 point input module (IC200MDL640) owned by a
different VersaMax PNS.
The input module (IC200MDL640) was configured for a 0ms Input
DC Filter time.
This system is identical to the B.1 – Multi-Device configuration,
except that MRP was in use. The network was set up in a ring
configuration and the PNC was configured as an MRP Manager with
a configured Default Test Interval of 20ms.
This system contained an RXi controller connected in a network bus
configuration to 64 VersaMax PNS modules (IC200PNS001), each
configured for a 16ms PROFINET update rate.
Each PNS contained at least one discrete input, discrete output,
analog input, or analog output module.
The I/O Loopback measurement was taken using a 16 point output
module (IC200MDL741) owned by one VersaMax PNS, that was
then tied to the 16 point input module (IC200MDL640) owned by a
different VersaMax PNS.
The input module (IC200MDL640) was configured for a 1ms Input
DC Filter time.
This system contained an RXi controller connected in a network
bus configuration to 64 VersaMax PNS modules (IC200PNS001)
and 64 third-party PROFINET devices.
Each PROFINET device was configured for a 16ms PROFINET
update rate and contained at least one discrete input, discrete
output, analog input, or analog output module.
The I/O Loopback measurement was taken using a 16 point
output module (IC200MDL741) owned by one VersaMax PNS,
that was then tied to the 16 point input module (IC200MDL640)
owned by a different VersaMax PNS.
The input module (IC200MDL640) was configured for a 1ms
Input DC Filter time.
