Click PLC Retentive Data Memory Registers

The Click PLC retentive data memory registers are not included in the program file by default. All Click PLC CPUs are included. This option must be selected to include the C, CT, DS, DD, DH, DF, CTD, and TXT memory in the Click project file.
We will be enabling the option to include the retentive data memory in the Click program file from the Click programming software. We will also be installing a battery and programming an expiry date. This will indicate when the battery will need to be replaced. Let’s get started.

More information can be obtained at our website. This includes all of the links mentioned in this video.

CLICK PLCs were designed with simplicity in mind, providing reliable control at a low, low cost and with little to no learning curve.
This simplicity makes CLICK a perfect solution for small machines, home automation projects, pneumatic applications, or anywhere a simple system needs a budget-saving control solution.
Building on the original CLICK’s simple design, the new CLICK PLUS PLCs offer the same practical control but with some surprising bells and whistles. Using the same FREE, streamlined PLC programming software as its predecessor, the CLICK PLUS PLCs provide no-headache programming combined with advanced capabilities like Wi-Fi communication and data logging.

Features of the new Click PLUS PLC (C2-0xCPU) includes the following:
• Micro USB
• DHCP support
• DNS support
• Wi-Fi (programming and Modbus TCP)
• Bluetooth (Wi-Fi) provisioning
• SD Card (Data Logging)
• Data Logger
• Network Time Service
• MQTT (Publish/Subscribe)
• Required PLC Password
• Disable Ports
• Strong Password Support
• Disable Ping Response
• Encrypted Password Transfer

There are several reasons why we are using the Click and Click PLUS PLCs. Here are just a few.
- Investment is low for the hardware and the software is free
- Standalone PLC with built-in I/O
- Communication ability - Ethernet Port, RS232, RS485 - support for protocols such as Modbus RTU, Modbus TCP, etc.
- Ability to expand the system with a variety of modules including RTD and Thermocouple inputs directly.
