1 Preface
1.1 Introduction to the Data Logger
This manual describes the installation, configuration, operation, and diagnostics of the
PLX51-DL-232. The PLX51-DL-232 can read and store data from Logix Controllers, DF1
Serial Interfaces, or Modbus devices. The PLX51-DL-232 has the capacity to store over
16 million records in its solid-state non-volatile memory. Each stored record includes a
Date Time stamp with a 50 ms resolution, Tag Name, Data Type, and Value.
The PLX51-DL-232 can be used to log data at a remote site with limited communication
with its base. The PLX51-DL-232 is also used to store records on mobile equipment
such as trucks, drilling rigs, or snow plows. Once the equipment returns back to its base,
the historical data can be uploaded and transferred to a more permanent storage device.
The PLX51-DL-232 can also be configured to collect data which is only downloaded and
examined if a fault occurs, otherwise the data is overwritten.
Figure 1.1. – Non-Historian Option
1.2 Features
The PLX51-DL-232 provides temporary extensive on-board storage capability for storing
process tags. A total of 16,777,216 records can be stored in its non-volatile memory.
Each record consists of the following data:
Table 1.1. – Components of a Record
Parameter
Link
Date Time UTC Time includes: Year, Month, Day, Hour, Minute, Second, Milliseconds.
Time has a resolution of 50 milliseconds.
Tag Name As defined in Controller or in the PLX50 Configuration Utility for other sources
Data Type BOOL, SINT, INT, DINT, or REAL
Value Logix Tag / DF1 File / Modbus Register value

PLX51-DL-232 Preface
Data Logger User Manual

The Log Index is managed by the PLX51-DL-232 and incremented each time a new
record is stored. The Unload Index is managed externally by the unload service. It is
only incremented after a record has been logged successfully to a text file. The records
can be unloaded in Logix with the Example Code. Both the Log Index and Unload
Indices loop around, eventually reaching the end of the cache. The cache becomes
100% full when the Log Index loops around and equals the Unload Index. In this
situation, either older records are overwritten (Log Mode = Overwrite) or newer records
are not logged (Log Mode = Hold).
Figure 1.2. - Memory Schematic
The PLX51-DL-232 is configured using the ProSoft PLX50 Configuration Utility. This
program can be downloaded from www.prosoft-technology.com, free of charge. The
PLX50 Configuration Utility offers various configuration methods, including a controller
tag browser. The PLX50 Configuration Utility can also be used to monitor the status and
download historical data to a local file.
The PLX51-DL-232 can operate in both a Logix “owned” and standalone mode. With a
Logix connection, the input and output assemblies provide additional diagnostics
information. This information is available in the Logix controller environment.
The PLX51-DL-232 uses isolated RS232 for DF1 communication. The RS232 port also
uses a terminal block for convenient installation.
A built-in webserver provides detailed diagnostics of system configuration and operation.

2 Installation
2.1 Module Layout
The PLX51-DL-232 has three ports at the bottom of the enclosure, as shown in the
figure below. The ports are used for Ethernet, RS232 serial, and power.
The DC power port uses a three-way connector (+positive, -negative, and Earth).
The RS232 port uses a four-way connector (Tx Transmit, Rx Receive, Gnd Ground, and
Shield earth connection).
The Ethernet cable must be wired according to industry standards which can be found in
the additional information section of this document.
Figure 2.1. – Data Logger side and bottom view
The PLX51-DL-232 provides three diagnostic LEDs (Ok, Act, and Eth). These LEDs
provide information on system operation, the Ethernet interface, and the auxiliary
communication interface (RS232).

Figure 2.2. – Module front and top view
The PLX51-DL-232 has four DIP switches at the top of the enclosure as shown above.

DIP Switch
Description
DIP 1 Used to force the PLX51-DL-232 into “Safe Mode”. When in “Safe Mode”, the
PLX51-DL-232 does not load the application firmware. It waits for new firmware to
be downloaded. This should only be used when a firmware update was interrupted
at a critical stage.
DIP 2 Used to force the PLX51-DL-232 into DHCP mode, useful when the user has
forgotten the IP address of the PLX51-DL-232.
DIP 3 Reserved
DIP 4 Reserved
