I/O Scanner Performance The TSXP575634M CPU used for the following measurements is at version 2.0, with its embedded Ethernet port at version 2.0. Time (ms) TSXP575634M CPU with Embedded Ethernet Port 32 devices 1 ... 16 devices PLC Scan Time (ms) The bottom curve shows that the response times for 1 to 16 devices are within 1 ms of each other. The response times for 32 devices are 9 to 10 ms longer initially; as scan time increases, the difference in response times becomes smaller. The table below shows the data used to generate the graph represented above. 380 Number of Devices to Scan Time from Scanned Device Input to Local Output (ms) TSXP575634M (v2.0) + Embedded Ethernet Port (v2.0) 10 ms Scan 20 ms Scan 50 ms Scan 100 ms Scan 200 ms Scan 1 device 23 42 102 201 402 8 devices 23 42 102 201 402 16 devices 24 43 103 202 403 32 devices 33 52 110 208 405 31006929 8/2007
