A-1.1 RX3i System Descriptions
Multi-Device with MRP (3i PNS)
This system contained an IC695CPU320, IC695ETM001, and an IC695PNC001 in the main
rack. The PNC001 was connected in a Media Redundancy Protocol (MRP) network of eight
RX3i PNS modules (IC695PNS001), each configured for a 1 ms PROFINET update rate. Each
PNS contained between one and nine discrete input, discrete output, analog input, or
analog output modules. The I/O Loopback measurement was taken using a 32-point output
module (IC693MDL740) owned by one RX3i PNS that was then tied to the 32-point input
module (IC694MDL660) in the same device. The input module (IC693MDL660) was set to
have a 0.5 ms input filter time.
Multi-Device
This system contained an IC695CPU320, IC695ETM001, and an IC695PNC001 in the main
rack. The PNC001 was connected in a network bus configuration to 20 RX3i PNS modules
(IC695PNS001), each configured for a 16 ms PROFINET update rate. Each PNS contained at
least two discrete input, discrete output, analog input, or analog output modules. The I/O
Loopback measurement was taken using a 32-point output module (IC694MDL754) owned
by one RX3i PNS, that was then tied to the 32-point input module (IC694MDL660) owned
by a different RX3i PNS. The input module (IC694MDL660) was set to have a 0.5 ms input
filter time.
