If a parameters configuring error is detected:
For U1660: Check METER CONSTANT
For U1661: Check LONFACTOR, LONOFFSET and P-FACTOR.
Start reinstallation:
At the control panel: by changing the neuron ID. For example, set the first digit to 1,
and then back to 0.
Reinstallation of all channels can be initialized via SETUP / LON / INSTALLATion.
At terminal window: For one channel with the following command
LonRE c = 1
For all channels with the following command
LonRE ** = 1
Repeat this procedure until the device type is recognized.
12.7 Additional LON Parameters
• Waiting time for responses:
SETUP / LON / TIMING CODE = 9 (
LONSTATTIMing = 9
)
Waiting time is set for a response with TIMING CODE.
TIMING CODE is an encoded value for the duration of
time allowed between a query and a response. The
default setting (9) should only be changed by experts!
• Time between two queries:
A delay can be selected here in order to reduced data
traffic in the bus.
SETUP / LON / POLL DELAY = 0 (
LonPOLLDELay = 0
)
POLL DELAY is time between queries from 2 channels
in milliseconds.
Example:
POLL DELAY = 300, 60 channels:
all channels are queried in 18 seconds.
Default: POLL DELAY = 0, 60 channels:
all channels are queried in 5 seconds.
