Single Device
This system contained an RSTi-EP Standalone Controller with embedded PROFINET EPSCPE100/CPE115 and
IO Scan in Normal Sweep mode. The embedded Ethernet is connected to PME. The embedded PROFINET
Controller CPE100/CPE115 was connected to a single RSTi-EP PNS (EPXPNS001) configured for a 16 ms
PROFINET update rate. The PNS contained 10 I/O modules with combinations of discrete 4 point in/out
modules & analog 4/6 channel in/out modules. Each I/O module had its outputs tied to the inputs of an
adjoining I/O module. The total data Bytes size is 122. The I/O Loopback measurement was taken using EP-
2214 (DO4) & EP-1214 (DI4) discrete modules and EP-3124 (AI4 V/I 12BITS) & EP-4264 (AO4 V/I DIAG) analog
modules.

Single Device Max-IO
This system contained an RSTi-EP Standalone Controller with embedded PROFINET EPSCPE100/CPE115 and
IO Scan in Normal Sweep mode. The embedded Ethernet is connected to PME. The embedded PROFINET
Controller CPE100/CPE115 was connected to a single RSTi-EP PNS (EPXPNS001) configured for a 16 ms
PROFINET update rate. The PNS contained 64 I/O modules with various combinations of discrete 4/8/16 point
in/out modules & analog 4/8 channel in/out modules. Each I/O module had its outputs tied to the inputs of an
adjoining I/O module. The total data Bytes size is 713. The I/O Loopback measurement was taken using EP-
2218 (DO8) & EP-1218 (DI8 2-wire) discrete modules and EP-3124 (AI4 V/I 12BITS) & EP-4264 (AO4 V/I DIAG)
analog modules.

Max-Device
This system contained an RSTi-EP Standalone Controller with embedded PROFINET EPSCPE100/CPE115 and
IO Scan in Normal Sweep mode. The embedded Ethernet is connected to PME. The embedded PROFINET
Controller CPE100/CPE115 was connected in a network bus configuration to eight different PNS modules (4 -
EPXPNS001, 1 - RX3i CEP001, 1 - RX3i PNS001, and 2 - VersaMax PNS001), each configured for a 16ms
PROFINET update rate. All the devices contained 96 I/O modules with various combinations of discrete 4/8/16
point in/out modules & analog 4/8 channel in/out modules. Each I/O module had its outputs tied to the inputs
of an adjoining I/O module. The total data Bytes size is 1262. The I/O Loopback measurement was taken on
device EPXPNS001 using EP-2218 (DO8) & EP-1218 (DI8 2-wire) discrete modules and EP-3124 (AI4 V/I 12BITS)
& EP-4264 (AO4 V/I DIAG) analog modules.

4-Device with Ethernet Protocols
This system contained an RSTi-EP Standalone Controller with embedded PROFINET EPSCPE100/CPE115 and
IO Scan in Normal Sweep mode. The embedded Ethernet LAN1 port was configured with 2 Modbus Client
channels with 200 data Bytes, 2 Modbus Server channels with 150 data Bytes, 2 SRTP Client channels with 256
data Bytes, 2 SRTP Server channels with 50 data Bytes, 2 EGD Producers with 800 data Bytes at 100ms
production rate each, 2 EGD Consumers, and connected to PME. The embedded PROFINET Controller LAN2
port was connected in a network bus configuration to four different PNS modules (EPXPNS001, RX3i CEP001,
RX3i PNS001, and VersaMax PNS001), each configured for a 16ms PROFINET update rate. All the devices
contained 70 I/O modules with various combinations of discrete 4/8/16 point in/out modules & analog 4/8
channel in/out modules. Each I/O module had its outputs tied to the inputs of an adjoining I/O module. The
total PROFINET data Bytes size is 831. The I/O Loopback measurement was taken on device EPXPNS001 using
EP-2218 (DO8) & EP-1218 (DI8 2-wire) discrete modules and EP-3124 (AI4 V/I 12BITS) & EP-4264 (AO4 V/I
DIAG) analog modules.
