Omron PLC programming software also increases the function block function block preparation software features to IEC61131-3A function block call a ladder exampleThe main purpose is to promote good function block structured programming, function calls; allow complex programs to create less code, more manageable process.A block from the block header and block body compositionPhysique - to … Continue reading Omron PLC programming software to use the function block
Frequency measurement for Omron PLC high-speed counter
By PRV instruction, you can read the frequency of the input pulse, high-speed counter frequency measurement, frequency is measured in Hz, hexadecimal 8-bit output, and can be used only in high-speed counter 0. In addition, also during high-speed counter 0 comparison operation at the same time, measurement frequency. Even in the frequency measurement, nor will … Continue reading Frequency measurement for Omron PLC high-speed counter
Omron PLC equipment disassembly sequence and method
(1) downtime must be two or more people care operations; (2) The front panel of the CPU mode selector switch from "Run" to "stop" position; (3) off the main power supply of the PLC, and then close the other to die Sakamoto power supply; (4) The power supply shelf connected to the power line wire number and remember … Continue reading Omron PLC equipment disassembly sequence and method
