Click to Click PLC Communication – Remote IO

Click to Click PLC Communication

We will connect two Click PLUS PLCs and communicate in three different ways. Using the send and receive commands, we will set up one PLC to be the master (client) and communicate with the slave (server). WiFi, Ethernet, and Serial communication will share common memory areas between the Click PLCs. The send and receive commands … Read more

BRX Do-More PLC High-Speed Input Pulse Catch

BRX Do-More PLC High-Speed Input Pulse Catch

The High-Speed Input Pulse Catch will set an output that can be seen by the PLC ladder logic scan in response to an input pulse. Inputs that are too fast to reliably be seen by the ladder logic scan time will be seen. The BRX Do-More series of programmable logic controllers have built-in high-speed inputs. … Read more

Click PLC Serial Communication Timing

Click PLC Serial Communication Timing

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. … Read more

Click Plus Real Time Clock Setup and Use

Click Plus Real Time Clock Setup and Use

The real-time clock on the Click Plus can now be more accurate. A network time service (NTP or SNTP) has been added to the Click Plus controller. This will allow the time to be synchronized with an internet time server or local network. Daylight savings time is quickly implemented with just a memory retentive bit … Read more

Click Plus PLC MQTT Communication

Click Plus PLC MQTT Communication

We will now look at the MQTT communication capability using our Click plus PLC. MQTT stands for Message Queuing Telemetry Transport. This simple ‘publish and subscribe’ communication protocol, does not take too many resources. Constrained devices with low bandwidth are ideal for MQTT. This protocol provides machine-to-machine (M2M) connectivity which is ideal for the Internet … Read more
