NOTE: If the communication settings have been changed they are activated upon exiting the
Maintenance Mode - the device carries out a soft reset. Alternatively power cycle will activate
the new communication settings.
Parameter Storage
The configuration parameters are stored in the non-volatile memory. When the changes are carried
out via the display, the parameters are stored in the non-volatile memory when the controller returns to
a normal display mode. If the changes are carried out over the network (Modbus), then "NonVol
Update" flag is required to be forced on to save the changes. When configured via the display, when
the parameters are stored after the timeout or exit button.
Modbus Registers
The controller supports the following Modbus registers and function codes. The default communication
speed is 9600 bps, 8 data bits, Parity None and 1 Stop Bit. The default Modbus Slave address is 1.
The device Parity can be changed between Odd, None and Even. The baud rate is selectable
between 9600, 19200, 38400, 57600 and 76800 bps. The table shows the register offsets starting
from 0 (0 Base) register address. For example, the Temperature is read from Modbus register 100
using Function Code 04. Some Modbus masters will require one to be added to Modbus registers (i.e.
1 Base). In this case Function Code 04, register 101 needs to be entered.
