A
B. – 16ms PROFINET Update Rate Systems
B.1 – Multi-Device
This system contained an IC695CPU315, IC695ETM001, and an IC695PNC001 in the main rack.
The PNC was 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 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 0ms Input DC Filter time.
B.1.1 – Multi-Device with MRP
This system is identical to the B.1 – Multi-Device configuration, except that Media Redundancy
Protocol (MRP) was in use. To exercise MRP, 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.
B.2 – Max Device
This system contained an IC695CPU315, IC695ETM001, and an IC695PNC001 in the main rack.
The PNC was 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.
