5.10.2.2 Energy configuration with the LIx Tags
The following parameters can be added to the eWON IO server in order to activate the energy support (enter Energy:1, validate and the other
parameters will be automatically added):
eWON4002
eWON4102
DI1... DI8 Status of input 1 to 8 on connector DI1-DI8 (top side)
CI1... CI8 Counter on input 1 to 8 on connector DI1-DI8 (top side)
LI1... LI8 Latched counter on input 1 to 8 on connector DI1-DI8 (top side)
DI9 Status of input 9 on connector Input/output (bottom side)
CI9 Counter on input 9 on connector Input/output (bottom side)
LI9 Latched counter on input 9 on connector Input/output (bottom)
DO1... DO2 Digital command of relay 1 and 2 on relay connector (bottom side)
DO3 Digital command of output 1 on connector Input/output (bottom)
BI1 Status of button (reset) on the front face
AI1... AI4 Value of analog input 1 to 4
AI5... AI6 Value of analog input 5 to 6 (PT100 probes)
Parameter
Default
Value
Energy
0 or 1 Enabled or not
Once Energy is defined, the eWON will automatically add the other parameters with
default value.
When 0, no energy computation at all are performed, saving eWON CPU resources.
Debug
0 or 1
Not automaticaly
added
When :1 all synchonisations are logged in the Real time event log.
RefTime
This is the reference time to compute interval. Letting this empty will start at 1/1/1970 00:00. You may enter
a date with hour in the form 08/07/2002 11:15:00 to set a new reference (usually not required).
IntTime
15 This is the integration time in MINUTES.
IntTolS
5
This is a tolerance on the integration time in SECONDS. If the measurment interval is shorter or longer than
this number of seconds, the period is considered as valid. For example IntTime=15 IntTolS =5 means
"interval is valid if between 11.14:55 and 11.15:05".
SyncIO 5
This is the IO number for clock synchronization. 0 means no synchro available, 1..8 is the IO number.
Synchonisation is based on the counter input associated with the digital input, each time the IO changes the
eWON will try to perform a synchronization (see also
SyncTolS)
SyncTolS
5
This is the tolerance for accepting the synchronization pulse in SECONDS.
If the synchronization pulse arrives outside the interval, the pulse is rejected. ERROR REPORT: the first
time the pulse is rejected, an error is logged in the event log. Next errors are not logged (except in Real time
log if Debug is enabled); When sync are accepted again, a trace is logged in the event file for the first
accepted synchonization.
REM: Because the internal clock has a precision of 1 second, the time is only updated if the absolute value
of the offset is greater than 1 (2 or more). Otherwise the offset jitters between -1 and +1 all the time.
