SERIAL COMM

The SERIAL COMM menu allows the programming of the communication
parameters of the COM1 and the option COM2.
• Address, is the address, node or logic number from 01 to 255 in Modbus
or from 01 to 128 in ASCII or from 1 to 126 in Profibus (with Profibus
option board inserted). 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 SW01 software with ASCII
protocol while with MODBUS protocol it must be set.
• COM1/COM2, are configured by the following submenus:
- Protocol, can be chosen between ASCII and MODBUS. The COM2 can be fixed on PROFIBUS-
DP or MODBUS TCP if it's an ANR96PRF or ANR96LAN instrument.
- Baud, transmission speed, programmable from 1200 to 38400 bps.
- Parity, parity sequence, programmable NONE-EVEN and ODD.
- DataBit, number of data bits, programmable 7 or 8 bit.
- Type, (voice that appears only for COM2 menu), is the type of serial port. It can be "RS485" or not
installed "none". In COM1 menu this voice doesn't appear because it's managed as RS232 and
RS485 by hardware.
Note: In the AN96PRF and ANR96LAN instruments the COM2 menu remain closed. The protocol on
COM2 will be PROFIBUS-DP or MODBUS TCP and the baud rate will be detect from the
communication bus and it's set automatically (see protocol manual).

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.
