4-2-2 Memory allocation in Software Set Range Operation mode
In Software Set Range Operation mode, memory allocation differs between when operating in D/A conversion mode (during
normal operation) and when operating in parameter mode.
<When operating in D/A conversion mode>
When operating in D/A conversion mode, memory allocation becomes as shown below:
Note: In D/A conversion mode, the digital input value register for channel 1 (offset address +4) serves also as the setting
command register (for changing over to parameter mode) and therefore interlock is necessary.
When a value in the range from “30000” to “32767” is input to this register, parameter mode is activated. Just after
parameter mode is activated, analog output value is equal to the offset value (0 V for the range of -10 to 10 V).
