INTRODUCTION
The FieldLogger is a high-resolution and high-speed data acquisition and logging equipment for analog and digital
signals. The result of an advanced technological development, the product is distinguished in diverse aspects, such as
high-performance, high-connectivity and ease of configuration and operation. This technology is presented as the ideal
solution for applications that require flexibility and functionality for diverse communication networks.
Its main features include:
•
Analog inputs: 8
•
Digital inputs/outputs: 8
•
Relay outputs: 2
•
2 MB internal memory
•
SD Card interface (up to 16 GB – not available in some models)
•
RS485 interface
o Main: Modbus RTU master and slave
o Auxiliary (DB9 connector – not available in some models): Modbus RTU slave
•
Ethernet services (not available in some models):
o DHCP
o HTTP (web page)
o FTP (client and server)
o SMTP (e-mails sending)
o SNMP
o Modbus TCP
•
USB:
o Host
o Device
•
HMI (human-machine interface – optional)
There are four input channel types in the FieldLogger: analog, digital, remote and virtual. Analog and digital channels
are those acquired directly by FieldLogger through their respective inputs. The remote channels are those acquired
through Modbus RTU protocol, operating as master on its RS485 interface. Virtual channels are a special type of input
channel where mathematical operations can be carried out, allowing the calculation of complex formulas from the
measured information.
The analog input channels are configurable for reading voltage, current, thermocouples, Pt100 and Pt1000 signals.
These inputs count on the precision of a 24 bit A/D converter with high acquisition speed, which can reach 1000 samples
per second. The digital channels can be configured individually as inputs or outputs.
The Ethernet interface allows data download and data access of the inputs and outputs, through services that can be
individually enabled and configured. Through a web browser (HTTP), one can visualize the data of the enabled channel,
diagnostics and general information of the FieldLogger. FTP client can be used for logging data downloads.
FieldLogger can identify up to 32 distinct alarm conditions, allowing the triggering of outputs, sending e-mails or SNMP
traps whenever an alarm condition is detected. All the information relative to the variables, status and diagnostics of the
FieldLogger are available in Modbus registers that can be accessed through the Modbus TCP interface or the Modbus
RTU interface available either through USB interface (device) or RS485 (when operating as slave).
The USB Interface device is used for connection to a computer for configuration, monitoring or download. Whereas the
USB interface host is used for connection of a USB flash drive, for data downloading from the logging memory.
The data logging memory can be transferred by any of the interfaces to the configuration software, which allows the
exportation for the most diverse data formats.
When the indication of the measured data from the process is necessary, an exclusive color graphical display HMI
(Human-Machine Interface) can be attached or installed remotely (optional).
