O=0: Sets the voltage output mode (-10V to 10V);
O=1: Sets the current output mode (+4mA to +20mA);
O=2: Sets the current output mode (0mA to 20mA);
O=3: Channel OFF;
O=4: Sets the voltage output mode (-10V to 10V);
O=5: Sets the current output mode (+4mA to +20mA);
O=6: Sets the current output mode (0mA to 20mA);
Example: H3310
CH1: voltage range (-10V to 10V);
CH2: voltage range (+4mA to +20mA);
CH3CH4: Channel OFF;

2) [BFM #5]
Data holding mode: While the programmable controller is in the STOP mode, the last output value in
the RUN mode will be held. To reset the value to the offset value, write the hexadecimal value in BFM #5 as
follows:
Example: H0011
CH1 and CH2=offset value;
CH3 and CH4=output holding;
3) [BFM #8 and #9]
Offset/gain setting command: Changes offset and gain values of channels CH1 through CH4 by writing
1 to the corresponding Hex digits of BFM #8 or #9. The current values will be valid until this command is
output.
O=0: Holds the output
O=1: Reset to the offset value
