Hi All,
I have dim and distant experience of building PLC systems 10+ years ago (when I did some work with siemens hardware), but nothing recent so I'm not up on the current offerings from manufacturers. I now have a requirement to replace an old hardware based control system (mainly relay logic) which has a reasonable amount of I/O. the system I am looking at has :
46 x digital inputs
45 x digital outputs
12 x Analogue input
12 x Analogue output.
Id like to keep all the I/O within the same enclosure which is a 19" 6U unit. All I/O is presently connected to the old unit via 8 D-sub connectors.
The system is used to switch on / off and monitor some power supplies as part of a larger system and applies some very simple logic and sequencing to them. It has a front panel of illuminated buttons, which I would seek to replace with a HMI panel.
Id rather avoid using distributed I/O if at all possible
Would anyone recommend any particular manufacturer and product family.
