■Offset/gain initialization request (b5)
Turn offonoff to enable the settings of buffer memory areas.
Offset/gain initialization is not to be performed unless Offset/gain initialization enabled code is set to E20FH.
When 'Offset/gain initialization request' (Un\G70, b5) is off, 'Offset/gain initialization complete flag' (Un\G69, b5) turns off.
■Operating condition setting request (b9)
Turn offonoff to enable the settings of buffer memory areas.
For the timing of turning the signal offonoff, refer to the following.
Page 131 Operating condition setting completed flag (b9)
■User range write request (b10)
In the offset/gain setting mode, turn offonoff this signal to register the values adjusted with the offset/gain setting in an
analog input module. The data is written to the flash memory at the timing when this signal is turned offon.
For the timing of turning the signal offonoff, refer to the following.
Page 132 Offset/gain setting mode status flag (b10)
■Channel change request (b11)
Turn offonoff Channel change request (b11) to change a channel to perform the offset/gain setting.
For the timing of turning the signal offonoff, refer to the following.
Page 132 Channel change completed flag (b11)
■Range switching request (b13)
Turn offonoff Range switching request (b13) to change a range of channel to perform the offset/gain setting.
For the timing of turning the signal offonoff, refer to the following.
Page 133 Range switching complete flag (b13)
■Error clear request (b15)
Turn offonoff Error clear request (b15) when Error flag (Un\G69, b15), Input signal error detection signal (Un\G69, b12),
Latest error code (Un\G0), and Latest alarm code (Un\G2) are cleared.
For the timing of turning the signal offonoff, refer to the following.
