4 Operation and visualization
4.1 Device info
Two function keys are available in the recorder menu Device info, which can be
used for communication and service purposes.
“Wink”
message A “Wink” message causes all the connected mTRON modules to flash their
service LEDs for 10 seconds at one second intervals (display “Wink received”
on the operating unit 70.4035). This function enables the identification of
mTRON modules which are not contacted by the recorder.
Service The “service-pin message” is only required with simultaneous use of the
JUMO mTRON-iTOOL project design software. Using this function, the posi-
tion of the recorder that is connected can be determined within iTOOL and re-
ported (“joining”).

Independently of the “Wink” function, the service LED of an
mTRON module flashes if a fault occurs in the module. The blink
characteristics of the mTRON module are described in the corre-
sponding installation instructions.
