Need help on MicroLogic 1500 online monitoring, what is the best way to connect a PC to micro logic 1500 PLC. what kind of cable is needed?

Pretty sure the 1500 has a 9-pin standard serial port, which is male, so you would need a serial cable with female on both ends. If it doesn't work initially, you need to swap wires 2 and 3, or get a 9-pin null modem adapter.

The most common cable to connect from a PC to a MicroLogix 1000, 1100, 1200, 1400 or 1500 controller is the 1761-CBL-PM02. These cables have a round "Mini-DIN" connector that plugs into the controller's Channel 0 port and have a female DB9 that plugs into your PC.

The MicroLogix 1500 model 1764-LRP controller and the MicroLogix 1400 controllers also have a DB9 serial port that is identical to the serial port on an SLC-500 or ControlLogix, so you can use a 1747-CP3 or 1756-CP3 cable to connect.

In most cases a straight-through serial cable with a null-modem adapter may be used in place of the 1747-CP3 or 1756-CP3 cable.

I know you use RSLogix500 software to program the SLC500 series processors (makes sense, cuz both end with '500'). What software do you need for the Micrologix

series? RSLogixMicro?

OK sit down because it may shock you to find out that you can actually program two different AB named hardware packages with the same product! You use the RSLogix500 package to program the Micrologix Line. I am sure that Rockwell wont mind if you want to purchase a separate RSLogix500 package for your micros... There is a freebie micro version that can be used to program the 1000 and 1100. I think I have heard it will work on other micrologix as well but I am not sure so dont bet on that one. There is a post about it on this forum.

MicroLogix controllers, despite their Logix-sounding name (they were released in 1995 or so !) use the SLC instruction set and operating system so they're really little SLCs.



I recently got the rundown from my A-B salesman on the variations of RSLogix 500. We use Standard because we use the whole line of MicroLogix and SLC-5/0x.

I don't have pricing handy.... I know Micro Starter is about $130, Starter is about $500, Standard is about $1100.
