CONFIGURATIONS - AIRGATE-MODBUS
BASICS
PAN ID
Choose a common identifier for each wireless network. All of the
AirGate-Modbus
devices from a same network must be
configured with the same PAN ID.
MODBUS ADDRESS
Each
AirGate-Modbus
must have a unique Modbus address. This address should be set before connecting the device to the
network. Modbus communication frames addressed to
AirGate-Modbus
will be handled by itself. Frames with any other address
will be forwarded.
This address is set in factory as 248, an invalid Modbus address, to avoid initial conflict with any other already configured Modbus
device in the network and should be changed to a unique address as soon as possible. While in Configuration Mode (status LED
flashing), communication parameters switch to 115200 bps, no parity, 2 stop bits and address 246.
BAUD RATE
Select for each interface the baud rate used by the Modbus network. All of the devices from the network must be configured with
the same baud rate.
PARITY
Select for each interface the parity/stop bits used by the Modbus network. All of the network devices must be configured with the
same parity/stop bits.
TIMEOUT
Timeout (in milliseconds) for the receipt of response bytes to the command sent to the slave station. Calculated automatically by
the software, according to the select baud rate.
For RS485-Master, RS485-Slaves and USB-Master operation modes, this parameter is only shown in the screen to help the setup of
the network master's
Timeout
, which must have its
Timeout
time configured with at least the
Timeout
shown in
DigiConfig
screen.
For Multi-Master operation mode, this parameter is used by the
AirGate-Modbus
, and may have its Timeout altered by the
DigiConfig
according to what is explained in the section “MULTI-MASTER” of the “OPERATION MODES” chapter. Noting that in this
case the
Timeout
configured in each network master must be at least
double
the time configured for
AirGate-Modbus
.
OPERATION MODES
According to the desired functionality the
AirGate-Modbus
can be configured with different operation modes. These are
distinguished altering the functions of the communication interfaces, as explained in the “OPERATION MODES” chapter. When
selecting a operation mode in
DigiConfig
, a figure containing a topology example will help in its setup.
ADVANCED
INTERFRAME TIME
The maximum time allowed (in microseconds) between the receipt of two bytes from a same package. This time is calculated
automatically by
DigiConfig
software. It must only be modified it any of the network slaves show a high communication error rate.
The "
Minimum time
” and "
Maximum Time
" values are shown in
DigiConfig
and range according to the lowest baud rate selected
for the interfaces in the “
Basic Configurations Guide
”. When clicking the “
Auto
” button the text box will be available for altering of
the "
Interframe Time
” which must obligatorily be within the band.
RF POWER
Alters the value of the transmission of the
AirGate-Modbus
. Valid values from 0 to 20 dBm.
SECURITY
The encryption of the packages may be enabled by selecting the “
Enable Security
” box. In case you wish to modify the security key
simply click “
Change Security Key
” and type a new key in the fields “
Typethekeyhere
”.
FIRMWARE UPDATE
This
DigiConfig
tab is used for the firmware update of the
AirGate-Modbus
.
The following steps must be followed:
1.
Locate the "Firmware" tab "Device Setup”.
2.
Select "Enable Firmware Update”.
3.
Click "Open” and search the new firmware file ("
.cbin
").
4.
Press the “Apply” button.
5.
Wait the Firmware update process conclusion. The
DigiConfig
will show a text box with the information
AirGate-Modbus
firmware recording performed successfully. Click "
OK
".
6.
The
DigiConfig
will turn back to the initial screen and the STATUS LED of the
AirGate-Modbus
will start to flash rapidly.
