Hello Navnag it all depends on how the I/O has been configured in the S5 155H system. S5 redundant I/O's (which I presume some of yoursare) could be used with or without the so called "error Locating Facility"(in simple terms this means thata redundant DI card pair required a "locating Digital outputs" cardand a redundant DQ card pair required a "locating Digital inputs" card, S5 H system had some rather "convoluted" and wiring intensive possibilities for redundant I/O's). Your "surplus" DI+DO modules in rack 1 could for example be used for the purpose of "error Locating Facility" (in which case you do NOT need it anymore in a 400H) OR it could simply be a single sided I/O card (in which case you would stillneed it in a 400H). You will need to determine first what the configuration of the S5 I/O's is before you can decide on the 400H configuration andto do soI suggest you do the following: 1.) Grab a copy of the S5-155H Programmable Controller (CPU 948R / CPU 948RL) Volume 1/2(seechapter 4 of Part I for all things I/O configuration related). It also won't hurt to download Volume 2/2 (Programming Guide) 2.) Ideally have (or get) a copy of COM 155Hand evaluate DX1 of the S5 program (it contains the I/O configuration, see Part III of the manual for more on it). If you can not get hold of COM 155H, get a copy of the electrical schematics and determine the I/O functionality from there. I hope this helps at least toget you started in the right direction |
