An array is a storage area for common data type tags. They usually have some relationship with each other and must be manipulated as a group. We can use arrays for motion control, recipe management, sequencing (indirect addressing), math, etc. The Productivity 2000 Series PLC uses arrays programmed using the Productivity Suite Software.
Previously, we defined an array and used this in an indirect addressing program. It indirectly sequenced bits on an output card. 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 eight or 16-bit array tags.
Let's start with our final look at our Productivity 2000 Series PLC arrays.

There are several reasons why we are using the Productivity 2000 Series Controller. Here are just a few.
CPU with 5 communication ports
50MB user memory - Can handle very complex applications quickly.
Limitless PID – Autotuning – Individual or Cascade Mode - etc
OLED message display on the CPU module
Plenty of discrete and analog I/O modules
Status displays on all discrete I/O modules
I/O Modules have QR codes. This can be scanned to have the module's latest specifications/wiring diagrams.
OLED data display on analog modules
P2-RS remote I/O expansion module, or use the Productivity1000 P1-RX remote expansion module to add even lower-cost remote I/O to your system
FREE full-featured Productivity Suite software
Programming with several ports - USB, Ethernet, Serial
Hardware auto-discovery
Hot-swappable I/O - Remove cards with power on the system
Choose from three wiring options
Slim DIN rail density form factor:
hardware - power supply, CPU, and seven modules in only 10-1/2 inches
All project files (program, tag name database, and all the program documentation) in the CPU
Run-time editing and debug mode on CPU
Easy data logging with micro SD on CPU
Secure Web server to access data files and system tags
Easy drive and motion controller integration
Coordinate motion control with PS-AMC allows management of up to 16 axes and synchronization of up to 4 axes
Two-Year Warranty

The Productivity 2000 series of programmable logic controllers currently has all these features built into the P2-550 CPU.
This CPU (Central Processing Unit) is also known as PAC (Programmable Automation Controller) because of its communication capabilities.
