Plc-2

[Robobob 0]

I would like to connect to a Plc 2 Processor with my laptop using AI PLC 2 software. I need a cable pin out. So I can make one up. Can anyone help me out. PLEASE! I am intending on using the serial port on the laptop. Thanks in advance Bob :*-(

The PLC-2 front port isn't a conventional RS-232 port, so a simple "wiring diagram" won't do the trick. You need a PLC-2 "smart cable" to connect your computer's serial port to the front port of the PLC-2. Only A-B sells those. There's an Australian company that sells a programming package that works with some PLC-2 models, but I haven't heard any feedback about them. PLC-2 isn't something I advise beginners to try; they're old enough that they should be left to guys who already have invested in the software and hardware to work with them.

Thanks for the input guys I should have mentioned that I have a PCMK com card. This is how I'am going. Searching the rockwell site I found some more info. You can communicate to the PLC 2 from you Laptop through a 1784-PCMK module with a 1784-PCM2 cable. Note: Laptop must have a PCMCIA slot available. Any software.This cable is $270 If your are using AI software you can use a PLC 2 serial smart cable 9399-L2103. This will connect to the 9 pin serial port on your computer and connect to the PLC 2 programming port (15 pin). This cable is $3100 ouch! If your computer has a 16 bit ISA or EISA expansion slot you can use a 1784-KTX. The cable is 1784-CP15. Any software. Use can also use a 1784-KT with a 1784-CP2 cable. Have a great day everyone

"Ouch" is one word for it ! :*-( I've been told that the "Smart Cable" is an RS-232 to current-loop serial converter, so that something from B&B or Black Box might do the same job. But I've never read specifics about it. The price for the Smart Cable is of course less of a money-making device and more of a mechanism to encourage users to upgrade away from this obsolete and expensive-to-support controller.
