FX 40 Manual

[skwsproul]

Does anyone have a pdf copy of the manual for an fx40. The little one that comes with it, with the wiring diagrams. I am trying to do mod and n2 on one and need the wiring diagram to ensure where to tie the modbus.

It won't work on a 40, you'll need a 60. 40's only have one rs485 port and is not expandable. 60's come with one but you can get an expansion card for two more.

[skwsproul]

That is what I thought but I read somewhere about someone doing it and I was not 100% sure.

[skwsproul]

So I am hosed there is no way to bring in a RM7800 burner interface into the jace.

There is a second com port on the FX40, but it is RS232 not RS485. You would need a converter, but it should work.

Or you could use a converter to go from the rs485 to IP and use the modbus tcp/ip instead of serial.

I though both of them were on the same COM port?

Its the lower rj-45. You will have to make it. I cant remember the pinout off the top of my head.

I think checkvalve is refering to using an ethernet to rs-485 device (router ?) that get connected to the LAN (TCP/IP) and the other side goes to the RS-485 device. I have heard of them but I don't know if you can load a driver for modbus into an FX-40.

Hoping for answer on the modbus.

skwsproul, do you still need the pdf for the install manual ?

email in profile if ya do.

Yes, but I thought you could only use one at a time?

look under C:\%Niagara_Installation_Folder%\docs\MtgWiring\JA CE-403

[freddy-b]

Nope, I have a 485 N2 bus and modbus pluging away together on several 40's.

[freddy-b]

Yes, but I thought you could only use one at a time?

Upon further review, I use lon not n2 on the 403's/40's at the buildings with modbus. Freek may be right.

That's what freeks are for, right?? :confused:

They show different leds for COM1 (serial port) and COM2 (rs485 port). Looks like I am wrong...

I may be thinking about the modems...

[skwsproul]

OK now I am lost. I found a disc with stuff from the JCI fx class and the only thing I can find is "The FX40 includes one RS-232 communication port where you can connect an external modem for remote dial-up access. Alternatively, you can order the FX40 with a factory-installed modem." So does this mean that the 232 can be used with an adaptor for modbus? The only modbus I have used is integrating the rm7800 into existing lon projects, so I have no idea if this will work.

[ddcfreek]

Is this existing or new?

If it's new, just get the fx60 and be glad you did. You can get the modbus driver and rs485 expansion.

If it's existing, I have never tried to use COM1 for anything before. It looks like it might work, but I have never done it. You can get the modbus driver for the 40's too.

[skwsproul]

Its existing unfortunately. Trying to decide if it is worth it to try this or get a fx20.

Simple answer, YES it will work. Both ports can be set up for rs485 as well as rs232. In your station look for the port settings. I have done this many times and used lon as well with all three.

OK and they all work together at the same time. Just to be 100% sure. Thanks

I am currently looking at the serial port settings and I think I see what you are talking about, but I do not see the setting to change com 2. Will that show up when I ad the modbus to it?

In the Niagara folder are the doc files, there is one on setting up comm ports, and yes they will and do work at the same time.

THANK YOU:)

So... if you put the modbus on COM1 (RJ45) port it would stand to reason that you lose the functionality of using "System Shell" on the port.

Is that correct ? Is that a problem ?

[skwsproul]

You have to put a jumper in to put it in shell mode.

[Cagey57]

No offense but I know that (the jumper part).

My question is, if that port is Modbus/RS-485 will the shell still work ? I simply don't know, never been to that point (with 2 RS-485's on an FX-40).

The more I learn the less I know !

You can get the shell to work by setting the port back to rs232. After your done doing shell set it back to rs485 or you can leave it rs232 and put a converter in.

Sorry. I was kinda thinking that there is not normally a lot of nead to use shell mode and I was not sure if you knew that.

After I reread that i realized what you were asking and I am not sure if the port would revert to shell mode when rebooted with the shell jumper in. I would think so because the platform is in shell mode and has not yet started the station. It has been a while so I am not sure if the platform even starts a station in shell mode. HMMMM interesting. Hopefully the Tridium boys thought of this one.
