1PREFACE
1.1 Introduction to the PLX51-DLplus-232
This manual describes the installation, configuration, operation, and diagnostics of the PLX51-
DLplus-232. The PLX51-DLplus-232 can read and store data from Logix Controllers, DF1 Serial
Interfaces, or Modbus devices. The PLX51-DLplus-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-DLplus-232 can be used to log data at a remote site with limited communication
with its base. The PLX51-DLplus-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-DLplus-
232 can also be configured to collect data which is only downloaded and examined if a fault
occurs, otherwise the data is overwritten.
Compared to the PLX51-DL-232, the PLX51-DLplus-232 has the following additional features:
Trend up to five variables dynamically via the integrated webserver
Upload logged data directly from the integrated webserver
REST API support retrieves data automatically via JSON-encoded messages.

1.2 Features
The PLX51-DLplus-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:
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

The Log Index is managed by the PLX51-DLplus-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).
Memory Schematic
The PLX51-DLplus-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-DLplus-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-DLplus-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.
