The Omron CP1H programmable logic controller has several different table data processing instructions. These instructions are used to handle table data, stacks, and other ranges of data.
We can define a stack of data. With this data, we can then do the following: add new data by pushing onto the stack, use FIFO (First In First Out), use LIFO (Last In First Out), find the current stack size, and read, overwrite, insert or delete from the stack. Dimension record tables are used to define the length of each record and the number of records. We can then write and read these records. This is ideal for data acquisition projects.
Other instructions found in the table data processing instructions include searching, summing, and finding minimum and maximum values.
We will be looking at these instructions in the Omron CP1H PLC. Examples of the instructions will be presented.
