9.2.9 Modbus Configuration Registers for the Analog Output
The I/O base board has two analog outputs that are selectable as 0 to 20 mA (factory default) or 0 to 10 V. To change the
analog output characteristic, physical jumpers must be change on the I/O board and a parameter Modbus register must be
changed.
For step by step instructions on changing the output characteristics see
Analog (DAC) Outputs for the B1 and S1 Models
on
p. 32.
Parameters for Analog Output 1 start at 4001 through 4008. Parameters for Analog Output 2 start at 4021 through 4028.
