See description of setpoint function.I/O bits (Coils)The instrument has a number of I/O bits that the master can write to usingModbus function 05 or 15.Each of these I/O bits are linked to a command in the instrument, which is describedpreviously in this manual.Set the I/O bit with the same number as the command that should be executed.The action is activated if the master sets the I/O bit to 'ON'.If the master sets the I/O bit to 'OFF', this is accepted, but no action is activated.All I/O bits are WRITE ONLY. This means the master cannot read the I/O bitsbut only write to them.Note: If the master tries to write to more than one I/O bit (Modbus function 15)the instrument will act on the lowest I/O bit number only.6-24
