Direct Logic PLC's
Direct Logic PLC's
(OP)
Hi,
Does anyone have any experience with Direct Logic PLC's.
I just visited thier web site, and the pricing is very inviting. We currently use Allen-Bradley every where. However, we are open to new things. Can anyone relate Direct Logic's limitations and or advantages (besides price).
I'm most curious about the handling of analog I/O and PID loops.
thanks,
Ken Moore

RE: Direct Logic PLC's
The I/O addresses are pre defined such as each slot has a memory range that is consumed by it. But they can be changed (if only to keep everyone confused.) They are not the I:2/4 they look more like X246, and then you would have to know where X246 was. Unlike AB there is only one type of memory although the memory is divided in to groups there is still only one type of memory "V memory" so it is possible to over write sections of memory.
Also, if you are an old guy and miss your RPN HP 11C calculator this is the Directsoft software is for you. But if you are one of though new guys with you TI-86 this means when you add some thing it goes like this
A+B=C
LOAD value A into memory
ADD value B to memory
MOVE memory to Value C
Well that a quick skiny.
I would Highly recomend thier switches they have no draw backs.

Keep an eye out for the new catalog in a month or two. Quite a few of the issues you have brought up are solved:)
I'm not in sales or bean counting....just an applications/support guy for ADC.

The programming software is IMHO very easy to use and understand. The stage programming, which is kind of like a free-form function chart, is pretty nice once you get used to it.

Only place AD tech support is lacking is on Software Products they market... In my experience.
