Can you provide the complete catalog number of your Omega transmitter. And the Analog card.
10volts to power a transmitter is very unusual.
And where is the 10 volts coming from on the PLC side?

Actually that's a symptom of the other pandemic we are having.

HMMM? Have you tried removing the .abc part?

Do you have RSLogix500? Version should not matter.
What software do you have? FYI the free version will only work with a ML1100 and a ML1000 program.
What kind of error are you getting when you try to open it?
Post the file here and someone can create a pdf file of the program for you.

June 29th, 2016, 08:26 AMOne method to determine the PLC-5 address is to use a computer with RSLinx Classic software to browse the network.
Connect a computer to the 1785-KE with a suitable cable (ideally a 1784-CP10, but any null modem cable will do) and set up an "RS-232 DF1 Devices" DF1 Full Duplex driver with the appropriate COM port number and the 9600 baud, BCC serial settings. The "Autoconfigure" button may not work; do not depend on it.
The important part is to set up the DF1 Full Duplex device with the Device Type = "1770-KF2/1785-KE/SCANPort". That will cause the RSLinx driver to browse for all the DH+ node numbers on the DH+ network.See above from the mastercts_user -
What works is most important. And easy enough to understand.

Good to hear you solved your problem.
I did see the other forum's responses also, great minds think alike.

Was there anything connected to channel 1 ?
The port may not be configured for DF1 protocol.
Do you have the offline file to check how the port is configured?

No, but double check the pin-out

3 to 2
5 to 5

First, not all USB to serial adapters work.
Second, not all USB to serial adapters support "Autoconfigure"
You might try configuring the driver DF1 in Rslinx's manually.
Default for your controller's channel 1 is..
DF1 full-Duplex
Baud rate 19.2 kbps
Parity none
Station 0
No handshaking
Error BCC
Data bits 8
stop 1

A ML1500 does not support Ethernet. Is there an adapter in between the HMI and the ML1500?

See link.. It is an online curve software to generate a formula for you.
Then just use a compute instruction.
