11.4) SERIAL
COMM
The SERIAL COMM menu allows the programming of the communication
parameters of the COM1 and the option COM2.
•
Protocol
, can be chosen between ASCII and MODBUS.
•
Address
, is the address, node or logic number from 01 to 255 in
MODBUS or from 01 to 128 in ASCII. This number identifies the node in a
network and consequently the instrument or the peripheral of a serial
multidrop network.
This parameter is set freely. This parameter is set automatically using NRG software with ASCII
protocol while with MODBUS protocol it must be set.
•
COM1/COM2
, are configured by the following submenus:
-
Baud
, transmission speed, programmable from 1200 to 19200 bps.
-
Parity,
parity sequence, programmable NONE-EVEN and ODD.
-
DataBit
, number of data bits, programmable 7 or 8 bit.
-
Type
, type of serial output to manage.
COM1 may manage RS485 or RS232.
COM2 may manage RS485 or RS232.
11.5) AVERAGE
The AVERAGE menu allows the settings of parameters in the calculation of
average values.
•
Sync Avg
, defines the type of the synchronism for the start and the stop
of the average calculation. Three mode of use are available:
-
Int.Rtc
.: use the internal clock as time based line. The average
calculation start when the clock changes the minute.
-
Ext.DI
: use the digital input 2 (Di2) to synchronize the start and the stop
of the average calculation. The digital input will be set as ExtDI automatically.
-
Int+Ext
: mixed mode. The digital input will be set as ExtDI automatically.
No congruent operation of digital input type and Sync. Avg will involve the
visualization of the warning message on the display (see for example in
this figure).
•
Type
, defines the type of the window used to the average calculation:
fixed (the updating depends of the Average time) or mobile (the updating
depends of dt Mobile).
•
Time Avg
, integration time for the calculation of the average parameters.
•
dt Mobile
, defines the updating time in window mobile of the average
parameters.
