Modbus Parameters Tab

– Modbus: with this setting you can activate ("On") or deactivate ("Off")

communication via a Modbus network.

Note: in order to activate the setting of this parameter the Condair RS

must be switched off and on again.

Factory setting: Off

Options: Off or On

The following parameters appear only if the Modbus function is activated.

– Modbus Address: with this setting you determine the Modbus address

for the Condair RS for the communication via a Modbus network.

Factory setting: 10

Setting range: 1 ... 247

– Parity: with this setting you set the parity bit for the data transfer.

Factory setting: Even

Options: None, Even or Odd

– Baudrate: with this setting you set the Baudrate for the data transfer.

Factory setting: 9600

Options: 110, 300, 600, 1200, 2400, 4800, 9600, 19200,

38400, 57600, 76800 or 115200

– Register Sequence: with Modbus communication 32 Bit oating-point

numbers are transmitted in two registers of 16 Bit each. In order that

sender and receiver understand each other (that means both use the

identical partitioning of the 32 Bit to the two 16 Bit registers) it must be

determined whether the high-order register (MSR = Most Signicant

is transmitted rst. With this setting you determine which register is

transmitted rst when transmitting oating-point numbers.

Factory setting: LSRrst

Options: LSRrst(low-order register is transmitted rst)

 MSRrst(high-order register is transmitted rst)
