Monitor display
The monitor display in normal mode corresponds to the main display. It allows
reading the display values on the back of the units. In menu mode the display
represents a menu for the unit parameterization (see 'Parameterization').
Status indicators
The status indicators (LEDs) on the back of the unit have the following function:
PWR
The unit is supplied with voltage.
DATA
Data transfer active (short flashing)
ERR
Data transfer faulty (short flashing)
Control
The units must be parameterized before they can be controlled. Parameterization is
done in a menu (see 'Parameterization').
The units accept the Modbus RTU (Remote Terminal Unit) as an operation mode.
They are slaves in the sense of the Modbus over serial line specification and
implementation guide and support the code 16 (0x10) Write Multiple Registers
according to the Modbus application protocol specification.
The indications in the above mentioned documentation are to be observed. Both
documentations are available at 'www.modbus.org'.
For the Modbus control the RS485 interface is to be used. The RS232 interface is
determined for testing and not to be used as Modbus interface.
