Data Logger Plus

PLX51-DLplus-232

The PLX51-DLplus-232 Data Logger is ideal for remote sites with limited communications that need to log data. OEMs can log their machine’s data to identify operational problems or efficiency improvements and can view this data online as trends via an integrated webserver. The trend data can be exported as a CSV file. The module supports REST API to collect JSON encoded data from the module that can be sent to other systems.

The PLX51-DLplus-232 can read and store data from EtherNet/IP™ PLCs, DF1 Serial PLCs and devices, or Modbus® PLCs and 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, Tag Name, Data Type, and Value.
