Pairing of a WPM data holder, activate tool monitoring
If a WPM data holder is supposed to be automatically monitored by the WPM Gateway, a pairing
with the required WPM data holder must be carried out. The following steps must be performed
for this purpose:
•
Selecting the WPM data holder by sending the index of the WPM data holder in
‘Active Tool’ (RxPDO1).
•
WPM Gateway acknowledges the index in TxPDO1
•
Sending ‘1’ in ‘Command’ (RxPDO1) to the WPM Gateway
•
WPM Gateway acknowledges the command in TxPDO1
•
WPM Gateway sets bit 4 in ‘Tool State’ (TxPDO1) (active pairing process)
•
The WPM Gateway activates all the WPM pressure sensors assigned
to the WPM data holder (sleep mode ended) via Bluetooth. Among other things, the time for
activation depends on the number of assigned WPM pressure sensors, the
WPM pressure sensor programming, the WPM data holder programming and the reception
strength of the Bluetooth signal. It can last from several seconds to several minutes.
•
After successful activation, the gateway deletes bit 4 in ‘Tool State’ (TxPD01) and activates
bit 5 in ‘Tool State’ (TxPD01) (pairing process completed,
tool monitoring active).
•
The WPM Gateway acknowledges the index of the monitored WPM data holder in
‘Monitored Tool’ (TxPDO1)
•
Sending ‘0’ in ‘Command’ (RxPDO1) to the WPM Gateway to complete the pairing process
•
WPM Gateway acknowledges the command in TxPDO1
The WPM Gateway now monitors the selected tool on its own. If one of the WPM sensors re-
ports a warning or an alarm, the respective bit is activated in ‘Tool State’ (TxPDO1).
If the WPM Gateway could not successfully complete the pairing process, bit 1 (alarm) is acti-
vated in ‘Tool State’ TxPDO1. In this case as well, the pairing must be completed by sending ‘0’
from ‘Command’ (RxPDO1).
