BRX Do-More PLC to Modbus TCP RTU Remote IO Controller BX-MBIO

The BRX Do-More PLC can communicate to a remote I/O (input and output) controller modules using the Modbus protocol for communications. The BX-MBIO provides both Modbus RTU and Modbus TCP interfaces. Modbus RTU is a serial communication and Modbus TCP is an Ethernet communication. Modbus RTU is supported over an RS-485 serial connection. Modbus TCP is supported over an Ethernet connection. They function as listening/replying devices (slave, server) and can connect with any mastering (master, client) device that communicates using the Modbus protocol.
Previously we looked at the BX-MBIO Modbus RTU TCP Remote IO Controller wiring and configuration.

Modbus RTU TCP Remote IO Controller BX-MBIO

The BX-MBIO Modules are remote I/O controller modules that provide a remote input and output (I/O) using the Modbus protocol for communications. They provide both Modbus RTU and Modbus TCP interface. Modbus RTU is a serial communication and Modbus TCP is an Ethernet communication. They function as listening/replying devices (slave, server) and can connect with any mastering (master, client) device that communicates using the Modbus protocol.
Modbus RTU is supported over an RS-485 serial connection. Modbus TCP is supported over an Ethernet connection. Any Modbus RTU master and Modbus TCP client that adheres to the Modbus.Org standards, and support the function codes listed can communicate with the BX-MBIO.
The remote I/O expansion units feature the following:

SIO-MB12CDR
– STRIDE discrete combo module, Input: 8-point, 12-24 VDC, sinking, Output: 4-point, relay, (4) Form C (SPDT) relays, 2A/point, (1) Ethernet (RJ45) port(s), Modbus TCP server.
SIO-MB04ADS

Our BRX Do-More PLC program will also take into consideration watchdog (communication time out) and power-up events for the Stride remote input and output units.

C-More EA9 HMI Series Headless RHMI to Solo and Click PLC Controllers




The cmore EA9 HMI has an event manager that can be used to trigger actions based on various events.

We will be adding a Click PLC to our headless RHMI cmore EA9 program that we created last time to communicate to the solo process temperature controller. The Solo will be connected via RS485 using the Modbus RTU protocol. Using the Modbus TCP protocol we will connect the Click PLC to the Ethernet port. Using the event manager we will be writing the set value (SV) and present value (PV) of the solo process temperature controller to the Click PLC. We will also allow the Click PLC to write the SV into the solo. This is in addition to the writing of the set value via remote apps and the solo itself. Let’s get started. Continue Reading!

C-More EA9 HMI Series Headless RHMI to Solo Process Temperature Controller




The cmore EA9 HMI can connect to the Solo process temperature controller using the built-in RS485 serial communication port. This will connect up to 32 solo units back to the HMI for display and control.

We will be setting up our headless RHMI cmore EA9 to communicate to the Solo process temperature controller. Using the information that we have discussed previously, we will set up data logging, file transfer protocol (FTP), bitmaps, etc.

We will also set up an object library of the Solo 4896. This will consist of a bitmap, numeric display, numeric edit, indication lights and up and down increment. The system will then be controlled using the remote applications discussed last time. Let’s get started. Continue Reading!

Stride MQTT Gateway to Adafruit IO

MQTT protocol is used for machine to machine (M2M), internet of things (IoT) communication. This publish/subscribe messaging is used where limited device resources are available or network bandwidth is low. The MQTT protocol provides small size, low power usage, minimized data packets, and efficient distribution of information to one or many receivers.

The Stride MQTT Gateway is an industrial 4.0 hardware component (IIoT – Industrial Internet of Things) that provides isolation and can easily interface with existing Modbus RTU and Modbus TCP communication protocols.

We will again be connecting a Stride MQTT Gateway to a Solo process temperature controller with Modbus RTU(RS485). The MQTT Gateway will communicate to the Adafruit IO Broker. The broker can display, log and allow us to control the data. This is done in an easily configured interface. Let’s get started. Continue Reading!
