Explain the Input and output limitation of the PLC?
With a PLC the I/O is fixed when you buy it. Smaller stand alone units are hardwired with the exact I/O you are going to have. Even expandable configurations have a fixed input and output memory table. The PLC scans its Boolean algebra logic, constantly and sequentially, and compares that program to the I/O tables' inputs, outputs and relays. Then it makes its' decisions depending on their state.

What limits the the number of virtual input and output instructions in a PLC ladder logic?
The only thing that limits the number of inputs and output instructions is the size/amount of the PLC memory.

What is memory organisation?
Memory can be organized into a one-word-wide organization, wide memory organization, interleaved organization and independent memory organization. The types of memory include HDD, RAM, ROM, and GPU.
What is a PLC Memory?
Memory is the component that stores information, programs, and data in a PLC. See more..... projuktiponno The process of putting new information into a memory location is called writing. The process of retrieving information from a memory location is called reading. Types of Memory The common types of memory used in PLCs are Read Only Memory (ROM) and Random Access Memory (RAM). A ROM location can be read, but not written. ROM is used to store programs and data that should not be altered. For example, the PLC’s operating programs are stored in ROM. A RAM location can be read or written. This means the information stored in a RAM location can be retrieved and/or altered. Ladder logic programs are stored in RAM. When a new ladder logic program is loaded into a PLC’s memory, the old program that was stored in the same locations is over-written and essentially erased. The memory capacities of PLCs vary. Memory capacities are often expressed in terms of kilobytes (K). One byte is a group of 8 bits. One bit is a memory location that may store one binary number that has the value of either 1 or 0. (Binary numbers are addressed in Module 2). 1K memory means that there are 1024 bytes of RAM. 16K memory means there are 16 x 1024 =16384 bytes of RAM.
What forma programmable logic controller training is available in Oklahoma City?
