Page 8 Operational instructions for digital multibus instruments 9.17.023

Digital instruments can be operated by means of:

1. Analog interface. (0...5Vdc/0...10Vdc/0...20mA/4...20mA)

2. RS232 interface (connected to COM-port by means of special cable (Default speed 38400 Baud)

3. FLOW-BUS

4. PROFIBUS-DP

5. DeviceNet

6. Modbus

7. EtherCAT

Option 1 and 2 are always present on Multibus instruments. Option 3, 4, 5 and 6 are optional. Operation via analog

interface, RS232 interface and an optional field bus can be performed at the same time. A special parameter called

“control mode” indicates to which setpoint the controller should listen: analog or digital (via field bus or RS232). The

RS232 interface behaves like a FLOW-BUS interface. When using more digital interfaces at the same time, reading can

be done simultaneously without problems. When changing a parameter value, the last value send by an interface will

be valid.

Also the micro push-button switch and the LED’s on top of the instrument can be used for manual operation of some

options.

• The green LED will indicate in what mode the instrument is active.

• The red LED will indicate info / error / warning situations.
