6 - 7
A) 4 bits are available, and 1 bit for filter processing is performed for continuous 4 channels in block.
Bit 0 : Filter processing enable/disable to channel 0,1,2,3 is specified in block.
Bit 1 : Filter processing enable/disable to channel 4,5,6,7 is specified in block.
Bit 2 : Filter processing enable/disable to channel 8,9,10,11 is specified in block.
Bit 3 : Filter processing enable/disable to channel 12,13,14,15 is specified in block.
B) Filter processing enable/disable to 4 channel in a bit shouldn’t be specified by channel.
(Ex. Filter processing to channel 0 and sampling processing to channel 1 shouldn't be specified.)
(2) G3F-AD4B
(3) G4F-AD2A
6.2.5 Filter Constant Setting Area (G3F-AD4A, G4F-AD2A: address 3 to 6, G3F-AD4B: address 4 to 19)
1) Filter constant setting can be specified to 4 channels of the G3F-AD4A, 1 channel of the G4F-AD2A and the
G3F-AD4B.
2) Filter constant setting range is 1 to 99.
3) When setting value is out of the range, error code number 16 is written to buffer memory address
31 to 34(of the G3F-AD4A) and the previous data remain as A/D conversion value.
4) When filter constant isn't set, filter constant will be set to 1.
5) Filter constant setting is as follows.
Filter constant setting to each channel
Address
G3F-AD4A
G4F-AD2A
address 3 Filter constant setting in block to channel 0, 1, 2, 3
Filter constant setting to channel 0.
address 4 Filter constant setting in block to channel 4, 5, 6, 7
Filter constant setting to channel 1
address 5 Filter constant setting in block to channel 8, 9, 10, 11
Filter constant setting to channel 2
address 6 Filter constant setting in block to channel 12, 13, 14, 15
Filter constant setting to channel 3.
Remark
Before average number/time constant value is set, average processing enable/disable specifying
and number/time average processing setting have to be set.
