Netload Robustness for Security test

[rottava]

Hello,

I have some questions regarding this test.

1. A PC with Ubuntu to run the SL1-Tester was prepared and it's working fine. Followed the instructions given by the document "How to install and to run the security level 1 tester V2.43.0.0_V1.0.pdf". This is sorted now.

2. Using "normal_d_V2.43.0_RT_CU_POF_V19.zap19" PLC program as example, changed 'dut' and 'd' devices to match mine.

But...

- My 'dut' (a 2-port device) is set to exchange 1 input and 1 output words for cyclic data. This is what I've done for all tests. However, PLC shows in the HMI an error message related to IO data. How should I proceed in this case?

- According to Figure 5-7 from document "Testspec-PN_2572", a switch "R" is required to connect all devices. Is it ok to use a Scalance XC208, the so called 'b' device for other tests?

- Should I add this 'b' device to my PLC program as well?

- I am not including information about topology, as already done for MRP Inter. Am I right?

Please let me know your comments about these points.

Best Regards,
Luciano.

Hi Luciano,

1. What exactly does the error message from the PLC say?

2. The Scalance X208 will not work for netload testing because it is a managed switch. An unmanaged "dumb" switch is needed for netload testing so the maximum network traffic is transmitted to the dut. The unmanaged switch won't need to be added to the TIA portal project.

You're correct that topology is not necessary for netload testing.
