Hi all,
I'm standing in on a project for commissioning on an S7 IM171-7F fail safe PLC.
I was told it had Ethernet Interface onboard but when I arrived I discovered it didnt, only MPI/Profibus.
I have no serial port on PC and was able to get comms up and running with a USB to serial converter and an MPI PC adapter. The speed of it was so slow and I kept getting thrown offline. I switched to a USB PC adapter which while stays online is draining the life out of me with speed.
Last time I used an S7 (8 years ago) we used CP5512 cards for programming which were quite good. I'm told there are not supported on VM machines and some dont even work on modern laptops? Is this true?
That being the case what is the best programming cable option available for S7's. I 'll get some ordered so this dosen't happen again.
Now my real question......
Also in the project I found a Hilscher NetX NL50-MPI adapter. Could this be what was meant by Ethernet interface? It appears to allow one program the PLC via TCP/IP through the MPI port?
Has anyone ever used one of these and if so would it enhance the speed? I have tried installing the drivers but I cannot get the Hilshcer application to even recognise the device to give it an IP address. I need to do this presumably before Simatic Manager will recognize it?
Any help greatly appreciated!
