9.11 remote consultation and confirmation of the
warning messages
If the power supply of the device is cut during the remote consultation, the device will generate for 2 s a
few 10 Hz-pulses on the output DO4 configured with the function "STATE" and the Process level will be
active when the power supply is restored.
When the remote consultation is active on the device:
• no dosing can be done.
• the digital inputs are only used for the consultation and the confirmation of the warning messages.
• the navigation keys are blocked, except to exit the consultation when"END" is displayed.
• the device state LED flashes.
Remote consultation and confirmation of the warning messages via the digital inputs is only possible:
• from the Process level,
• when no dosing is being done on the device.
• if at least 1 warning message has been generated (the output(s) configured with the function "WARNING" take
the value 1).
To use the feature:
→
Configure the device with the dosing mode "EXT. MEM", "EXT.+LOC", "EXT. [T]" or "EXT. REP".
→
Connect the 4 digital inputs DI1 to DI4 to 4 outputs of the PLC.
→
Configure DO1 or DO3 with the function "WARNING": see chap. “9.7.20”.
→
Connect the transistor output DO1 or the relay output DO3 to an input of the PLC.
→
In order for the PLC to be informed that the remote consultation has started or has finished, connect the tran-
sistor output DO4 to an input of the PLC and configure the output DO4 with the function "STATE": see chap.
“9.7.26”.

1. To remotely access to the warning messages, the PLC sends out the code 000 on the digital inputs DI1 to
DI3 then 1 pulse on DI4.
2. The device generates a 200 ms pulse on the output DO4 to confirm the access to the messages; The dosing
feature cannot be accessed any more.
