Productivity 1000 Series PLC Array Functions Part 3

An array is a storage area for a group of common data type tags. They usually have some relationship with each other and need to be manipulated as a group. Previously we defined an array and use this in an indirect addressing program. It sequenced bits in an output card indirectly. We then looked at the following instructions: Array Statistics (STA), Copy Array (CPA), Fill Array (FLA), and Shift / Rotate Array (SRA). We will now look at the final four array instructions: Pack Boolean Array (PBA) - Pack an Array of Boolean tags into a destination Word Array Pack Word Array (PWA) - Convert one 8 bit or 16-bit array into a 16 or 32-bit Destination Array tag. UnPack Boolean Array (UPBA) - Unpack an Array of Word tags into a destination Boolean Array. UnPack Word Array (UPWA) - Convert one 32 or 16-bit array source tag into four 8 or 16-bit array tags. Let’s get started with our final look at arrays in our Productivity 1000 Series PLC. More information can be obtained on our website.
