The Productivity 2000 series of programmable logic controllers has a slim DIN rail density form factor. This means that this micro-modular PLC can have a power supply, CPU, and seven IO modules in only 10-1/2 inches. Input and output cards can be installed, removed, or replaced without turning the power off to the PLC system. (Hot-swappable) This means that your system can remain running while troubleshooting your system hardware. The Productivity 2000 hardware supports up to 240 local I/O for discrete, analog, and motion applications with a high-performance CPU equipped with five communications ports and 29 discrete and analog I/O modules. Several remote IO options are available on this award-winning PLC in the Productivity series family.
Productivity 1000 (Stackable Micro PLC)
Productivity 2000 (Micro Modular Programmable Controller)
Productivity 3000 (Modular Programmable Controller)
These three series by FACTS engineering currently make up the Productivity Series PLC from Automation Direct.
We will be looking at the features of the powerful P2000 controller. Let’s start by looking at the P2000 hardware. Keep on Reading!
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that can be programmed. The gantry loader is one of these machines. It will pick up metal boxes from a conveyor and place two on a wooden pallet. The Click PLC will be used to program this virtual machine.
Using the Click Plus PLC, we will connect the simulator to the gantry loader machine. This will be done using Modbus TCP (Ethernet) for communications. Using the five steps for program development we will show how this is programmed. The logical sequence step will include a flow chart and a sequence of operations. The sequence of operations will be done using indirect addressing in the Click PLC. Let’s get started. Keep on Reading!
EasyPLC Software Suite is a complete PLC, HMI, and Machine Simulator Software package. This PLC learning package includes a Machine Simulator (MS). This virtual 3D world with real-time graphics and physical properties can communicate to several different programmable logic controllers. (PLC)
We will be developing a Click PLC program for a transfer line. This is just one of the prebuilt machines in the simulator to learn PLC programming. We will be developing the ladder logic, connecting via Modbus RTU, and testing our program. This will be done using the five steps to PLC program development. Let’s get started! Keep on Reading!
All Solo Standard Process Temperature Controllers that support RS-485 serial communications can use the SL-SOFT configuration and monitoring software. This free package will communicate to monitor multiple SOLO controllers using Modbus RTU or Modbus ASCII protocols.
We will be installing the SL-SOFT configuration and monitoring software package on our Windows 10 PC. Communicating through our Waveshare USB to RS485 adapter, Modbus RTU will be used as the protocol to establish communication. Let’s get started. Keep on Reading!
Many questions come from serial communications using the Click PLC. Most of these questions deal with communication timing when using multiple send and receive instructions. We will show you how to deal with serial communication timing in the Click PLC.
Receive and Send instructions will allow you to send and receive serial data to an external device. The communication method that you set up can be ASCII or Modbus. ASCII (American Standard Communication for Information Interchange) can be used to send to devices such as a printer. Receiving ASCII can be used for connecting barcode scanners to the PLC. The barcode will be read as an ASCII string in the PLC. Modbus serial communication (Modbus RTU) is a standard protocol used in many automation devices.
We will demonstrate the Send and Receive instruction by communicating Modbus RTU to a Solo Temperature Controller. Parameters from the Solo process temperature controller will be read using multiple receive instructions. The send instruction will be used multiple times as well to set the Set Value (SV) and Limits of the SV value entered in the temperature controller. The set values will only be changed when required. Let’s get started. Keep on Reading!
