Data formats

All data are collected and stored in internal ZetaScout device memory and can be exported in CSV, HTML, JSON, XML formats. ZetaScout device can push data directly to almost any database server, or can send data using your API.

RAW data output

Data fragment in simple RAW format how it stored in device memory, explained below.

RAW data output in HTML table format
(A) New day begin. Some extra data records with system options may be added.

(B) Employee ID at work place registered. (Worker at workplace 05:55:30)

Time interval from (B) to (C): workplace setup time. (4min 55sec)

(C) Task bar-code read (First task begin) (work starts at 06:00:25)

From (C) to (D) equipment for task Preparation/setup time (36sec)

(D) First equipment/worker action detected. ( after programmable timeout of new task in0 column value always 1) Please read [Downtime explained] below for downtime calculation algorithm.

(E) To complete whole task worked made 1+7=8 work cycles, Work time (1min 54sec)
No downtimes in whole task interval are detected.

From (E) to (F) time interval registered as Downtime (1min 20sec)

(F) Next task begin, Preparation/setup time

Jump to (C)

Notes:

in0 - work cycles counter
in1 - tool/equipment total ON time in miliseconds (1000 miliseconds = 1 second).

* This data also can be used to measure tool wear or to calculate scheduled maintenance.

Downtime explained

Maximum *takt time can be set for each workplace idividually. For example we set takt time to 30 seconds in zetaScout device configuration.

downtime explained

Steps:
1. Task barcode scan (STATUS prepare)
Interval from [1] to [2] is prepare time
2. First action detected, equipment prepared and task begin (STATUS work)
3. in0 data greater than 1, this means groups of events counted without going to downtime and delay betwwen takt event does not exceed workplace programmed downtime.
downtime explained 2
Record timestamp is exact moment of last takt pulse in this group of takt's
Interval from the end of [3] to [4] minus programmed timeout are calculated as downtime because there no action in longer than 30 seconds programmed period. (STATUS downtime)
4. in0 record value is 1 indicate thet process state returned from downtime to work .(detected first event after timeout) (STATUS work)
time interval betwwen [4]. and [1] minus programmed timeout are also calculated as downtime. (STATUS downtime)

*takt: Takt time is the rate at which you need to complete a product in order to meet customer demand. Takt time was first used by German engineers during the 1930s, later this concept started to be used in Japan. Toyota used it as part of the Lean principles.

Mechanical information

zetaScout workplace activity monitoring device made from ABS plastic and are avialable in 3 colors: Black, light Gray and White (rare used). Two versions of light towers are available: build-in, and external.

ZetaScout mounting

Installation of the device at the workplace is very important. The employee must be comfortable using the device, this will save time and make work more efficient. In many cases, our customers ask for the ability to easy way rotate, twist and move the device to comfortable position, in this case we pay a lot of attention to make the installation as simple as possible.
