While the 5/01 could communicate over a DH-485 network, it was only able to “respond” to messages sent it from either a PC or future SLC-500 controllers (5/02, 5/03, etc)Īs far as the Fixed SLC-500's are concerned, they shared all the same specs as the 1747-L511, except each had a limited number of build-in I/O points, and accepted a single two slot I/O expansion chassis. (Advanced Interface) programming software for the SLC-500, called “ PLC–500 A.I. Icom also release a version of it's popular A.I. SLC-5/01s could be programmed through their DH-485 port using either a Hand Held Terminal (a 1747–PTA1E installed in a 1747–PT1) or the SLC-500 version of Rockwell's 6200 software known as APS (Advanced Programming Software, 1747-PA2E.) Note: Please avoid plugging Ethernet device into SLC-500 DH-485 ports as it could damage your device and/or SLC. It's important to note that all SLC-500's with a native DH-485 RJ45 style port also provide power via that port for accessories like the original Hand Held Programmer ( 1747-PT1) as well as the DH-485 Link Coupler ( 1747-AIC.)

They both came with a DH-485 programming port that accepted an RJ45 style connector, a connector most readers today will associate with Ethernet cables. These processors had an average scan time of 8ms per 1K of program, and supported 52 Ladder Logic instructions. While the L514 used battery backed memory, the L511 had capacitor backed memory with the option to use a battery.īoth 5/01 models were said to be capable of controlling up to 3840 digital I/O points across a maximum of 3 I/O Chassis and 30 I/O Slots. It launched in a 1K memory version ( 1747-L511,) which was quickly followed by a 4K version ( 1747-L514.) The first controller to come out for SLC-500 modular systems was the 5/01. The 5/01 and Fixed Controllers: Modular and Brick That said, the first controllers released in the SLC-500 line were just mere shadows of the PLC-5… The SLC-500 also programmed with software and instructions nearly identical to the PLC-5. The most obvious reason was that it was smaller and less expensive than A-B's flagship product at the time, the PLC-5. The SLC-500 family of Programmable Logic Controllers was quite popular when it launched in the early nineties.
