Description
Available Configurations
Polling Mode
In this mode, the converter polls the network. There is no 201C on the
network. The
IVA-420I (master) polls the transmitters (slaves) and converts
the digital signal from the transmitters into a 4-20 mA analog signal.
Once set, the converter provides a 4-20 mA analog signal for the
transmitters at address 1 to 8 or 9 to 16 if the converter is connected to
channel 1 of the 201C, and 17 to 24 or 25 to 32 if the converter is
connected to channel 2. Each converted signal is associated with a
distinct output (J16 through J23).
Three statistic values are also available : Minimum, Maximum and
Average, with the appropriate settings. These values are available with
addresses 1 to 8, 9 to 16, or 1 to 16 if the converter is connected to
channel 1 of the 201C, or 17 to 24, 25 to 32, or 17 to 32 if the converter
is connected to channel 2.
Split Address Mode
(Listening or Polling)
This mode is used with a SQN8x (4 points, 2 gases). The SQN8x uses
4 points per gas. Addresses 1 to 4 are for the first gas and addresses 9
to 12 for the second gas.
On the IVA-420I , the addresses are fixed. Addresses 1 to 4 are attributed to
the first 4 outputs and addresses 9 to 12 are attributed to the last 4
outputs. This configuration allows for the use of only one
IVA-420I with a
SQN8x with two gases.
