[PSUBS-MAILIST] PLC HMI selection

[Alan via Personal_Submersibles]

Thanks Cliff,
glad to hear you have 49 I/Os, I thought I was getting carried away at 53.
My trouble is I want 41 analog inputs, & the Automation direct stackable micro
series only has 4 channels per slot, with a maximum of 8 additional slots.
I really liked that PLC but will have to compromise on my analog or look elsewhere.
Yes I like the idea of data logging. The PLCs first job will be monitoring my thruster
testing & logging temperature.
Thanks for the heads up on the screen size.
Cheers Alan

The current configuration on the R300 uses 20 analog input channels, 2 RDT, 10 digital input, 2 RS232, 6 analog output and 9 digital output channels.  I am currently using the D2-260 cpu but I would use the newer Do-more cpu if I rebuilt the system.   I would not use any smaller than a 8" HMI.  Programming the PLC ladder logic is straight forward.
