Chapter 6. BUFFER MEMORY CONFIGURATION AND FUNCTIONS

6.2 Buffer Memory Functions

Each address in the buffer memory occupies one word and it is represented with 16 bits.
In the 16 bits which compose an address, every bit can be set to either "1" when it should be turned On or "0"
when Off in order to implement the function of each bit.

6.2.1 Specifying Channel Enable/Disable

(G3F-TC4A : Address 0,
1) Temperature conversion enable/disable specification is possible on every channel.
2) Disabling unused channels makes the sampling cycle short.
3) No specification means that all channels are disabled.
4) The followings show temperature conversion enable/disable for each channel.
G3F-TC4A
Address "0"
G4F-TC2A/G6F-TC2A
Address "0"

6.2.2 Specifying the Type of Thermocouple

(G3F-TC4A : Address 2 to 16, G4F-TC2A/G6F-TC2A : Address 1 to 4)
1) Type specifying the thermocouple that is connected to each channel of the thermocouple input
module is possible by the channel.
2) Default is type K.
3) The followings show the number of specification for each channel.
Specification
No.

4) Other value than the defined values is set for specifying the type of a thermocouple, the G3F-TC4A
displays error code at the corresponding bit in the address 67 and the G4F-TC2A/G6F-TC2A in the
address 19 with the type being specified to "0", that is, type K thermocouple.
