commands. Please refer to Section 8 for the layout of Modbus Registers
that are available in the Omni30.
When the unit is in Switch set mode (refer to settings A or B of section 4.3), the unit may be
accessed via Modbus without changing the dipswitch settings at all. In this mode,
communications settings are fixed as follows:
Modbus Settings without changing SW1 or SW2
Modbus Slave Address
2
Comms settings
ASCII; 9600 baud; No Parity
Table 4-1a – Serial Port Settings with no change to SW1 or SW2
This form of access is made available for setup of input timer values and does allow users to
read status information for diagnostic purposes.
In applications where the Modbus Slave address and/or comms settings are to be different
from the table above then set SW1-8 ON to enable SW2 for additional serial port settings.
