How the #$@# do I do this???

the computer chip enchants me and piques my interest... what did they leave out of the com port on the hmi? driver hardware?? sufficient current capacity??? makes ya wonder sometimes.

Either channel on this ML is capable of DF1, may try using one of AB's port splitters. I have no idea what effect it may have when the modem is in use tho.

That would work but we need to connect to the 8way DIN because our modem is connected to com port 1

I believe its the hand shake. Ill find out more and post it ASAP.

That was what I was refering too, using the port splitter for com 1 to share it between the modem and HMI, just not sure what effect it may have.

Hmmm I dunno...I’m very new to all this and attempting to navigate my way through non standardized muck.
 
The 1747-DPS1 RS-232/DF1 port
​
splitter allows a single RS-232/DF1 port
​
on a Rockwell Automation controller
​
(e.g. SLC™ 500, MicroLogix™, PLC-5®,
​
ControlLogix®, CompactLogix™) to be
​
expanded (or split) for communication
​
with two external devices at the
​
same time.
​
From a single DF1 port, the splitter
​
creates one full-function port for twoway
​
communication between the
​
controller and a local network. The
​
second port is respond-only and is
​
primarily designed to run a programming
​
terminal or human machine interface
​
(HMI). Both the initiate/respond, and
​
respond-only


the one full function, and one not, may be an *** biter...

diagram on 1747_pp018A doesnt show a modem at all.

That may work but our modem sends data every 15 min during operation....plus our panel view displays real time data so im not sure but that sounds like a congested highway.
 
Looks to me like 3 choices.

Talk to AB and see if you can use the mini din port with a modem. I have done this so know it is possible but been awhile.

Buy the cable(s), if available, from the HMI manufacturer.

Get another HMI that offers a cable to connect to the 8 pin port that is available now.
 
One other option is to buy a NET-ENI and convert the 8 pin mini port to ethernet.

That way you can let the HMI talk Ethernet (no fancy cables required) and still be able to plug in to configure while leaving com 1 and the modem well alone.

This is assuming the Magelis has an ethernet port of course.
I just went this route with a Xycom and it worked a treat.
 
I would simply buy a 1761-PM02 and fabricate a cable to go from the DB9 end to whatever your HMI requires...No need to cut and splice anything...

The Net-ENI module is a good device too in my experience, and the splitter looks like it's worth a try too, but I have not used it...
 
If you look at the cable wiring given for the PM02 it does not show true serial type wiring, know if it has all of the 8 pins wired? I can not remember but it does not show either 2 or 3 connected. The picture is on this thread.
 
If you know your pinout..(by reading this thread, that would be NO) we can make you one.

The one that Ron link to on Ebay is mine, I sold it..., but we can make you a custom cable if needed, we do it all the time.

Send me a PM if interested.

4 and 6 are jumped and 9 on the dbf is NOT terminated, 1 and 8 on the DIN are not landed

So, GIT, do you have access to the 8 pin connector that fits?

Hi Paul,

We use a standard din and modify it... they fit very well, some use just a standard and they will fit but, you have to force them. The one thats hard to get is the 90deg version, ours and most others are straight, so like on a SLC you have to keep the small door open (not a big deal)
