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 conîšżguration software) or for the multidrop connection where
it is needed the use of OPT-RS485-ADV optional board. (Max 20 drives can be connected on the serial line).
The RS485 serial line format is: 8 data bits, no parity and one stop bit.

23.1.1 3800 Drive address UINT16 1 1 255 ERW FVS
Setting of the address to which the drive responds when connected to the RS485 serial line.

23.1.2 3802 Serial baudrate ENUM 38400 0 2 ERW FVS
Setting of the RS485 serial communication speed (Baud Rate).

23.1.4 3804 Serial protocol ENUM Modbus 0 1 ERW FVS
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.

23.1.5 3806 Serial delay ms UINT16 0 0 1000 ERW FVS
Setting of the minimum delay between the drive receiving the last byte and starting its response. This delay
avoids conicts 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

23.1.6 3808 Serial swap data BIT 0 0 1 ERW FVS
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.
