If for some reason I run out of space on the PLC, from what I understand I can just use the PLC as a Serial I/O Board connected to a laptop where all the programming can be stored. Is that correct? Will all the PLC functions (I/O) be available to be programmed on the laptop?

Thank you very much. Your explanation is very clear. This project is starting to take shape. Things are going well and after this pilot project we might have 10 more with Nissan and even more with other car manufacturers. Cant wait to get my hands on these PLCs they really seem wonderful hardware.


Again, I ask. Is there enough space to program two minutes of the described control in these units?

What do yo u mean by "could be in inverted states"? What will that depend on?
What does the T100MD2424+ have to prevent such thing from happening? I will be buying the T100MD2424+ anyways because there might be other stuff I want to control, but still please explain the above.
Also concerning the AO can I use a MOSFET transistor so drive the gauges?
In the end what would you recommend I use for driving the gauges? PWM or the AO with a transistor?
Also again the most important concern is if there is enough space on the device to program all these controls to run for two minutes.

Thank you.

Hello. First I would like to say sorry, I am really new to PLCs. Just yesterday I was on wikipedia reading what they really are. Truth is I am not very knowledgeable at electronics beyond basics. I am however on a crash course right now. The company I work for just got a huge project and the weird stuff got handed to me.

My company requires from me control a vehicle gauge cluster for two minutes. What I mean by that, is that the speed and tach gauge needs to be at any position I want it to be during those two minutes. I also need to control the speed of the transition between those two points. Basically I need to make the gauges seem like they are working on the road for two minutes. I figure I can do that with the PWM output. Is that correct? Can I also do it with the AO? What is the difference between the AO and the PWM?

Also I need to control the steering wheel with a stepper motor for two minutes like the car would be driven. Can someone recommend me a stepper motor and a stepper motor driver for such an application to be controlled by your PLC?

Also is there enough programming space on the device to program all these controls?

Thank you very much and again sorry for my "newbiness"
