Communication; Communication/Rs485 - gefran ADV200 Functions Description And Parameters List

23 – COMMUNICATION
23.1 – COMMUNICATION/RS485
The ADV200 drive is provided with a standard port (9 pole sub-D connector: XS) for connecting the RS485 serial line used
for drive-PC point-to-point communication (via the GF-eXpress configuration software) or for the multidrop connection.
The RS485 serial line format is: 8 data bits, no parity and one stop bit.
Menu PAR Description
23.1.1 3800 Drive address
Setting of the address to which the drive responds when connected to the RS485 serial line.
Menu PAR Description
23.1.2 3802 Serial baudrate
Setting of the RS485 serial communication speed (Baud Rate).
0 9600
1 19200
2 38400
Menu PAR Description
23.1.3 3810 Serial parameter
Setting of the format of the RS485 serial communication data.
0 None,8,1
1 None,8,2
2 Even,8,1
3 Odd,8,1
Menu PAR Description
23.1.4 3804 Serial protocol
Setting of the serial communication protocol:
0 Modbus
1 Jbus
Setting to 0 selects the Modbus RTU (Remote Terminal Unit) serial communication protocol.
Setting to 1 selects the Jbus serial communication protocol. The Jbus protocol is functionally identical to the Mod-
bus, except for the different numbering of addresses: in the Modbus these start from zero (0000 = 1st address)
while in the JBUS they start from one (0001 = 1st address) and maintain this difference throughout numbering.
Menu PAR Description
23.1.5 3806 Serial delay
Setting of the minimum delay between the drive receiving the last byte and starting its response. This delay
avoids conflicts on the serial line when the RS485 interface that is used has not been pre-set for automatic Tx/
Rx switching. The parameter only concerns the use of the standard RS485 serial line.
Example: if the delay in Tx/Rx switching on the master is a maximum of 20ms, the Ser answer delay parameter
must be set to at least 20ms: 22ms
Menu PAR Description
23.1.6 3808 Serial swap data
This parameter enables the exchange of the reading of the High and Low parts of the words for FLOAT,
UINT32, INT32 type parameters when using the Modbus protocol.
