Draw terminal wiring diagram of the control system; lists the I / O allocation table; design ladder.Analysis example1) Terminal Blocks2) I / O assignment Input Output QA-X0 KM-Y0 TA-X1 0 when input contact … Continue reading PLC circuit Program
PLC ladder program should be prepared in the following programming skills to master.1) more contacts in series at the top of the ladder circuit series 2) number of parallel contact circuit should be placed to the left, as shown in Figure 4-26. Figure 4-26 b) ratio of a) eliminating the 0RS and ANS instruction. Once … Continue reading PLC programming skills
PLC programming should follow basic principles.1) external input contacts, output relays, internal relays, timers, counters and other devices can be repeatedly used, without using complicated structure of the program to reduce the use of contacts.2) Each line of the ladder left the bus started, the coil connected to the far right, the right contacts can … Continue reading The basic principles of PLC programming
(1) Peripheral Communication Interface PLC with a variety of communication interfaces, PLC can communicate with the programmer, printers, other PLC, computers and other devices to communicate via these interfaces. It can be composed of multi-machine system or even into the network, larger control. (2) Expansion Interface For connecting the I / O expansion unit and special function … Continue reading PLC’s Extended Interface and peripheral communication interface
CPM1A series PLC has a rich instruction set, according to their functions can be divided into two categories: basic instructions and special function instruction. Its command functions similar to FX Series PLCCPM1A series PLC instruction mnemonics and operands generally composed of two parts, mnemonic CPU executes this command to complete the function, and the operands … Continue reading OMRON C Series PLC Instruction
The user program through the programming sequence entered into the user memory, CPU and the user program cycle scan order, which is the basic working process of the PLC. When the PLC is running, the user program has a large number of operations required to perform, but the CPU is not to perform multiple operations simultaneously, … Continue reading Execution after power PLC
Relays and the data area is divided into CPMl A series PLC internal relay area (1R),Special Auxiliary Relay Area (SR), Temporary Relay Area (TR), the relay holding area (HR), auxiliary relay memory area (AR), link relay area (LR), timer / counter area (TC) and data storage ( DM). CPM l A series PLC internal … Continue reading Omron CPM1A series PLC relay area and a data area
