A-2.2 VersaMax System Descriptions

A. – 1ms PROFINET Update Rate Systems
A.1 – 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.
A.2 – 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.
A.2.1 - 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 20ms.
A.3 - Multi-PNC001 Multi-Device
This system contained an IC695CPU315, two IC695ETM001's, an IC694MDL732, an IC694MDL645, and four
IC695PNC001 modules in the main rack. Each PNC001 module was connected in a network bus configuration
to eight VersaMax PNS modules (IC200PNC001), each configured for a 1ms 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 1 ms Input DC Filter time.
