The buffer memory of G3F-DA3V, G3F-DA3I, G4F-DA3V and G4F-DA3I are same. And the buffer memory of G4F-
DA2V, G6F-DA2V, G4F-DA2I and G6F-DA2I are same.
6.2 Buffer Memory Function
Each address of buffer memory has been occupied by one word, and it is displayed as 16 Bit.
▶
Each address is composed of 16 Bit, and each Bit can be executed by specifying Bit on to 1 or Bit off to 0.
▶
1) Digital input value can be used within the range 0 to 4000.
2) When digital input value isn't set, digital input value has to be set as follows.
Voltage output(G4F-DA3V/G4F-DA2V/G6F-DA2V) : 2000
Current output(G3F-DA3I/G4F-DA3I/G4F-DA2I/G6F-DA2I) : 0
Voltage output(G3F-DA3V) : 0
