3.4.9 Write data error codes (buffer memory address 19: Un\G19)
(1) The error codes generated by the A/D converter modules are stored here.
(2) See Section 8.1 for the details of the error codes.
3.4.10 Setting ranges (buffer memory addresses 20, 21: Un\G20, Un\G21)
(1) These areas are used to confirm the setting ranges of the A/D converter module.
(2) The setting values for CH1 to CH4 are stored in buffer memory address 20
(Un\G20) and setting values for CH5 to CH8 are stored in buffer memory address
21 (Un\G21). In the case of the Q64AD module, buffer memory address 21
(Un\G21) is invalid.
