A-2.2 VersaMax System Descriptions
1ms PROFINET Update Rate Systems
Single Device
This system contained an IC695CPU315, IC695ETM001, and an IC695PNC001 in the main
RX3i rack. The PNC001 was connected to a single VersaMax PNS (IC200PNS001) configured
for a 1 ms PROFINET update rate. The PNS contained four mixed discrete 16 point in/out
modules (IC200MDD844). Each I/O module had its outputs tied to the inputs of an adjoining
I/O module, and each input module was configured with a 1 ms Input DC Filter time. The I/O
Loopback measurement was taken using one of the IC200MDD844 modules.
Multi-Device
This system contained an IC695CPU315, IC695ETM001, and an IC695PNC001 in the main
RX3i rack. The PNC001 was connected in a network bus configuration to eight different
VersaMax PNS modules (IC200PNS001), each configured for a 1ms PROFINET update rate.
Each PNS contained at least one discrete input or 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 0 ms
Input DC Filter time.
Multi-Device with MRP
This system is identical to the A.2 – 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 PNC001 was configured as an MRP Manager with a configured Default
Test Interval of 20 ms.
