This analog and digital variables data logger featured 8 configurable analog inputs that could read thermocouples, Pt100, Pt1000, voltage and current signals. Accuracy was 0.2% of the span for thermocouples, and 0.15% of the span for other input types. Capable of performing mathematical operations in the input channels, this high-speed reading and logging device utilized a 24-bit A/D converter enabling up to 1000 samples a second and a suite of connectivity options including a 10/100 Mbps Ethernet interface that allowed for access through a browser (HTTP), FTP (client and server), e-mail sending (SMTP), SNMP and Modbus TCP. A precision plastic hybrid 10K-ohm potentiometer delivered a voltage divider output signal that was linearly proportional to the travel of the spring-loaded measuring cable, based on the movement of the grain bins, which the FieldLogger then read and recorded at 1 reading an hour. CAS DataLoggers recently provided the datalogging solution for GSI Grain Storage in Assumption, Illinois, the world's largest manufacturer of steel farm grain bins, commercial storage grain bins and grain silos, as well as grain dryers and material handling systems including grain bin sweeps, spreaders, chain loop systems, commercial bucket elevators and conveyors. GSI Grain Storage installed a Novus FieldLogger data acquisition system in a grain storage bin that was repeatedly loaded and unloaded into the storage floor area to measure the separation of the floor sections.

Flexible and rigid cables or bars for power transport can be installed in a power panel. In a three-phase system, instruments can be installed that measure the single electrical parameter, one per phase, or a voltmeter and a current can be installed with the voltage and current switches, allowing the measurements to be displayed in sequence. The plank floor was sectioned out like a house's wooden flooring section, and personnel needed an industrial data acquisition solution capable of reading voltage and connecting to a string pot to read and record its measurements to learn where these separations were and their extent. The only possible reference is the reading of the displayed value, for example, of the current. This high performance and high connectivity equipment also offered personnel easy configuration and operation to get the project underway as quickly as possible. It also offered 2 relay outputs and 8 digital ports individually configurable as inputs or outputs.

This versatile datalogger proved to be a cost effective solution for handling analog, digital and other types of variables with high resolution and speed and also offered expansion modules. There are many different types of serial communication protocols like I2C and SPI which can be easily implemented with Arduino and today we are going to look at another most commonly used protocol called RS485 which is very commonly used in high noise industrial environments to transfer the data over a long distance. To provide a convenient means of attaching two grounds to the serial cable, there are several pins (labeled GND) on the communications connector that are connected to the controller’s ground plane. It consists of two insulated copper conductors twisted together, which helps reduce electromagnetic interference and ensures signal integrity. Likewise, the terminal’s transmit signal TxD is connected to the QScreen Controller’s receive signal RxD1. The normal way to implement this is with a two wire system with differential signal levels. To ensure that no two devices drive the network at the same time, it is necessary that each slave device be able to disable its own RS485 data transmitter.

The flexible RS485 Cable is ideally suited for any industrial application.

The pymodbus library is far more comprehensive than minimalmodbus in that you can do a lot more with it. I've tried using the ftdi d2xx drivers to connect to it, but so far I can't read any data and while the writes don't fail, I'm not sure they're working. However, the length can be extended considerably with a trade-off with slower data rates. This is a sensor that can collect data for Electrical Conductivity (EC) and Total Dissolved Solids (TDS) in Liquids. NTI's RJ45 RS485 Sensor Port Hub for E-16D Large Enterprise Environment Monitoring System adds eight RJ45 RS485 sensors to the E-16D.
