A-2 PACSystems* RX3i PROFINET Controller Manual – December 2011 GFK-2571A
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 PNC was connected to a single VersaMax PNS (IC200PNS001) configured for a 1msec.
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 1ms 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 PNC 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 0ms 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 PNC was configured as an MRP Manager with a configured Default Test Interval of 20ms.
A.3 - Multi-PNC Multi-Device
This system contained an IC695CPU315, two IC695ETM001’s, an IC694MDL732, an
IC694MDL645, and four IC695PNC001 modules in the main rack. Each PNC 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 1ms Input DC Filter time.
