Schneider Modicon Quantum PLC

[ScottyUK]

My site is shortly going to receive a Modicon PLC incorporated within a larger system. I'm likely to be the first port of call on this system, although I'm not familiar with this model of PLC. Most of my PLC experience is on Allen-Bradley's SLC5's, with a little on the Siemens S5.

Does anyone have any opinions, good or bad, about the Schneider product? Any known weaknesses or common faults I'm going to meet? All comments warmly received.

On the assumption that I can get hold of Modsoft, can anyone confirm the pin connections of the serial cable to connect a laptop to the PLC? I have the following:

1 - 1
2 - 3
3 - 2
4 - 6
5 - 5
6 - 4
7 -
8 -
9 -

Are these connections correct / complete?

TIA.

Hi Scotty,

Yup that looks OK but you also need to short pins 7 & 8 on both ends

Kevin,

Thank you very much. I had a fleeting chance to bell out sonoeone's cable and totally overlooked the links within either connector and only took the end-end results. Not so clever as I thought at the time!

Hi scotty,

No prob.

I have a drawing of this cable which also shows the screening arrangements. If you want a copy you can either post your email here or leave it at the 'Send e-mail'
link at the bottom of my website home page.
