MicroLogix 1000 has a perfectly good serial port that supports DF1 and DH485 protocols. You can connect up to it with any serial modem, or a radio modem.
Does management just want a data log for this one pit pump, or do they want to bring that conductivity alarm data into their ShopLogix facilities management and analytics software system ?
What format do they want the data log in ? Just a text file ? An entry into an Excel document ? An entry into a table in an SQL database ?
A lot of modern IOT and SCADA systems start with the EtherNet/IP protocol used by the MicroLogix 1100 and 1400 instead of going to the trouble of connecting to legacy serial systems.
If you've got a TCP/IP network near this controller, either WiFi or radiomodems or ordinary Ethernet, then you can get a purpose-built "EtherNet/IP to DF1" converter equivalent to the old 1761-NET-ENI.
The Net-ENI would even power straight from the MicroLogix port (which has a +24V DC pin on it). A modern equivalent is available from Real Time Automation, part number
515RTAENI.
Or if you've got a SCADA system that does support good old DF1 Full Duplex, you can use a commercial off-the-shelf serial server that doesn't know anything about industrial protocols. Presumably you want something fairly rugged like a LanTronix UDS1100 or Moxa NPort 5110. From your ShopLogix or SCADA system perspective, they're just using whatever COM Port Redirector utility the vendor provides.
If your question is "what SCADA platform is right for my site and purpose", that's a bigger question.
Any platform that is more than a toy is going to support OPC and OPC-UA if it doesn't have an A-B serial driver, so buying an install of Automation Toolbox or Kepware for this controller should be a tiny component of your sitewide SCADA architecture and budget.
Because the answer to "what SCADA should I choose" on this forum is "Inductive Automation IGNITION", I will note that MicroLogix and SLC-500 controllers with only serial ports are supported by the "MicroLogix via Net-ENI" driver with the browse option disabled, and of course a Net-ENI or equivalent. To my knowledge, Ignition doesn't support direct serial connectivity via DF1 protocol.
