RSTI-EP PROFINET I/O Controller User Manual
GFK-2571R
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.
16ms PROFINET Update Rate Systems
Multi-Device
This system contained an IC695CPU315, IC695ETM001, and an IC695PNC001 in the main
rack. The PNC001 module 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 0 ms Input DC Filter time.
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 PNC001 module was configured as an MRP Manager with a
configured Default Test Interval of 20ms.
Sixty-four IO-Device
This system contained an IC695CPU315, IC695ETM001, and an IC695PNC001 in the main
rack. The PNC001 module 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 1 ms Input DC Filter time.
