Programmable Logic Controller Analog I/O Module XGT Series User’s Manual z Read this manual carefully before installing, wiring, operating, servicing or inspecting this equipment. Simply convert your analog output value to a percentage (0-100) and input that percentage into the "Scale_analog_output" library function provided by Siemens (see link above). iv ACS 500 Programming Manual Warnings, Cautions, and Notes ARNIW NG! Your drive contains dangerous voltages when connected to the line power. To meet the specifications, you should enable analog input filters for all inputs of the module. In RSLogix 5000, the screen would look like this. Hardware with Analog Inputs. Programming software, such as CX-Programmer, is used for programming on a PC. By utilizing two of these registers MODBUS can support the IEEE 32-bit. The naming convention for CLICK PLC memory addresses uses X to indicate "real-world" inputs, and Y for real-world outputs. These input devices include sensors, push buttons, limit switches, etc. Follow the procedure below to confirm that the analog data can be properly read out. Thanks for your supports. A variety of discrete and analog I/O modules are available for flexible. programming will be done online so that changes can be immediately tested. As You can see in the above picture that we have converted the data received by PLC in to 0 to 100 accordingly. 5 EXAMPLE PROGRAM. more effectively. - Inputs 5 and 6 can function as either digital or analog inputs. More specifically, we present a technique for the system to measure analog inputs using an analog to digital converter (ADC). HOW PLC INPUTS WORK. Includes 1 PLC,1 Training Module with 4 discrete inputs and 4 discrete outputs, 1 analog input , 1 analog output, power switch, programming cable (our USB-SC09-FX), power cable, sample program, Flash Drive, PDF version of operating manual, Flash drive is the programming software (1000 word version), manuals and drivers for USB adapter and lessons. The process of sam-pling the data is not instantaneous, so each sample has a start and stop time. It allows the user to learn about PLC logic programming, different PLC programming languages, PLC to PC communication, etc. MELSEC-L CPU Module User's Manual (Function Explanation, Program Fundamentals) Operating procedures are explained using GX Works2. Like analog inputs, analog outputs are generally connected to a controlling device through a transducer. 2 Logic Symbols, Truth Tables, and Equivalent Ladder/PLC Logic Diagrams www.
