6.3 RFID Reader
These OCUs have an additional feature option of a 125kHz RFID reader that can be used in two primary modes
1. User Authorization; where the user needs to hold the OCU to an ID badge at start up to be able to select
an operational mode. This means that an OCU can associate an ID badge identity (person) to a specific
machine and a specific set of available commands, or if no match is found not be able to start the OCU.
2. OCU Configuration to match a specific machine; where the user needs to hold the OCU to an ID TAG
located on or near a machine at start up, to be able to select that specific machine. This means that an
OCU can be owned by one user but used freely to control many different machines.
These two are similar and both required a database that cross references either Authorized User identities or
Machine Identities to a specific System Address and set of configuration parameters. This database is then
loaded into the OCU and used at startup.
6.4 Data Logging
These OCUs feature a fault and data logging capability that provides users with the ability to diagnose
any intermittent operational issues and records the total switch activations for planned maintenance of the
OCU.
The Associated MCUs feature enhanced logging capabilities with totalizers and run time per motion that
enable planned maintenance and data-analytics.
The OCU logs specific data as shown in the table below, the MCU has extensive data logging that goes
beyond this data set.
Data log events and switch totalizers can be downloaded over a Bluetooth link using the Configuration PC
tool.
OCU Logs are shown in sequence, MCU logs are shown against a Real Time Clock
