There are two option: 1) PC Step 5 with cable6ES5734-2BD20 2) PG Step 5/Step 7 with cable 6ES5734-2FB00 Unfortunately,both option are not working with this CPU and I'm not sure why. Both option are working perfect with CPU 95, 100 and 115, but not with 948 - where is my mistake? Any help will be muchappreciated, cause I'm at sea, my internet is very limited and I'm just a user.

I have tried to connect directly to the CPU, but there was a path (PG/AS511-H1-H1-ENDP) in the project settings. I have just presumed, that for point to point connection, the path should be removed. From other side, my attempt to connect the PG720 to CP5430 (6GK1543-0AA01) as per the path settings (via cable 6ES5734-2FB00) was unsuccessful. According all documentation, I will be not able to go online through CP5430 with my PC (STEP 5 7.23) and cable 6ES5734-2BD20, cause there is no supply +5V from this CPU to pin 14, but there should 't have problem for PG720 and cable 6GK1543-0AA01. Am I right about the above? Kind regards Nikolay 1st elector-technical officer m/v ORIANA

You should be able to use both your PC and PG to connect to CPU directly without any other interface between. 2. As you have mentioned, 6ES5734-2BD20 can only be used with PG. I have the attached the manual for CPU948. Take a look at chapter 11. Regards, Behnam www.sigmaprocess.ca/blog Attachment S5-155U-CPU948.pdf (76 Downloads)
