If you have a SLC 500 processor: Category # L551-1747, SER: C proc Rev: 5
OS: 1747-OS501, SER C, FRN 9th
when switching, LED status: FLT all days of
solid red, RUN forever. Other (BATT, strength, ENET, RS232) stops blinking or off.
try, you can communicate with the processor 232 can not connect.
I appreciate all your input. If you need more information, ask here.
Try removing the battery, and either for about 1-2 minutes, or use a jumper, where he was waiting in the short remaining battery voltage involved.
If any of REpower CPU and the LED patterns are still there, and you can not connect, then the CPU is probably pooched
Understanding in this case
Processors were back to our office on a separate bench to put the same theoretical examination. While they are at various booths on plants that were installed in delayed, but we feel through rack / power supply from different backgrounds was a good idea. Our test has the same rack as the shelves in this area.
Yes, these devices have been installed and is running every day for about four years. The batteries were the false ads, so we went to replace them.
Yes, we were looking at remanufactured processors. I had to explain how it causes confusion. (more…)

I am nearing the end of the project, which is the Omron PLC, CJ1M series communicates via Modbus network with SCU41 map read / write, send and receive data over a network. However, I came in recently with a problem that all my work is to discover anything.
I have functional block for each type of folder on the network, whether existing or regulator circuit, it is just a block and move it vypracuje scheme plus serves as a black box, the ‘t you see what he does, just results.
But since many, many lines of comparison I Uinta mapping different data types in different network elements (aka, the program automatically inserts know weather its efforts to create UDINT, Floating Point and collect the necessary data), I had too many steps and ran from UM. I changed it from a CPU11 CPU22, and everything should be good. However, I am now the error message “Internal error. Malfunctioning block instances generated code” that prevents me from sending my program to a new CPU. Only one of my FB seems immune to this error. Any help? (more…)

Programmable logic controllers (PLCs) are widely used today for industrial automation and control for the factory assembly lines. Unlike general-purpose computer, the PLC is designed for operation in harsh environments, and most manufacturers offer a wide range of I / O and communication options to choose from.
While the basic concepts of PLC programming are common to all manufacturers differences in the I / O addressing, memory organization and instruction sets that PLC programs are never perfectly interchangeable between different makers. Even within the same product of a manufacturer, different models are not directly compatible.
For real-time systems, our diverse experience in various manufacturing environments has enabled us to specialize in a variety of PLC brands and platforms. Some well known brands of PLC, we also know: Allen Bradley, Siemens, GE Fanuc, Omron, Modicon / Telemecanique, Toyopuc, Mitsubishi, Bristol Babcock, SCADAPack Series, Koyo, and Panasonic (Matsushita brand). Our team of experienced engineers and programmers, you need all your design and programming assistance. (more…)
