The productivity series of PLCs comes with 4 built-in communication ports for easy connectivity to your PC or various industrial networks. Ethernet protocols like Modbus TCP can be utilized with the RJ45 port on this PLC. Modbus TCP is an open (published) protocol that uses the Server (Master) / Client (Slave) architecture. It’s a very common protocol used in industrial automation controls.
We will be using the RJ45 (Ethernet) port to communicate to a Click PLC. Modbus TCP will be the protocol used on this Ethernet communication media. The Productivity 1000 PLC will be the server and the Click PLC will be the client. We will be creating a network between the two PLC units. A heartbeat will be used so if communications are lost, the server (slave) will know. The throughput time will be timed by using a small program in the Click PLC. You will soon see how the Productivity Series of PLCs is the best way to handle communication with other devices. Let’s get started.

There are several reasons why we are using the Productivity 1000 Series Controller. Here are just a few.
- 50MB user memory - Can handle very complex applications easily.
- 4 built-in communication ports – Easy connectivity to your network.
- Data logging up to 32 GB on a microSD card
- Add up to 8 IP modules to communicate to your field sensors. This will give you a total of 128 discrete IO points or 32 analog IO channels.
- Free Software and 30 days of free training with every CPU from Automation Direct.
- Interactive PLC Configuration Tool
- Tag Names
- Auto-discovery IO – Physical I/O tags will be generated based on each module’s position in the base.
- I/O Modules have QR codes under the wiring cover. This can be scanned so you can have the latest specifications/wiring diagrams for the module.
- Limitless PID – Autotuning – Individual or Cascade Mode - etc
- Web Server and Mobile Access
- Advanced Software instruction set
The Productivity 1000 series of programmable logic controllers currently has all of these features built into the P1-540 CPU.
This CPU (Central Processing Unit) is also known as MPU (Multi-Processing Units) because of its communication capabilities.
