Not used.
Sets the operating mode for the limit warning function. This
setting applies to all 8 inputs.
0: Mode 1 (normal warning)
1: Mode 2 (sequence warning)
Refer to 2-3-8 Limit Warning Function for more details.
Sets the data type of the conversion data to binary or BCD.
This setting applies to all 8 inputs.
0: Binary
1: BCD
Turn these bits turned ON to disable A/D conversion for the
corresponding input. Bits 00 through 07 correspond to inputs
1 through 8.
0: Conversion enabled
1: Conversion disabled
corresponding input, as follows. di i f ll
(The first bit is the higher bit.) (The first bit is the higher bit )
00: –10 V to +10 V 00: 10 V to +10 V
01: 0 to 10 V 01: 0 to 10 V
10: 1 to 5 V/4 to 20 mA 10: 1 to 5 V/4 to 20 mA
11: Not used.
Turn these bits turned ON to execute the scaling function for
the corresponding input. Bits 08 through 15 correspond to
inputs 1 through 8.
0: Scaling function won't be executed.
1: Scaling function will be executed.
Refer to 2-3-5 Scaling Function for more details.
Turn these bits turned ON to execute the mean value
function for the corresponding input. Bits 00 through 07
correspond to inputs 1 through 8.
0: Mean value function won't be executed.
1: Mean value function will be executed.
Refer to 2-3-6 Mean Value Function for more details.
Turn these bits turned ON to execute the square root
function for the corresponding input. Bits 08 through 15
correspond to inputs 1 through 8.
0: Square root function won't be executed.
1: Square root function will be executed.
Refer to 2-3-4 Square Root Function for more details.
Turn these bits turned ON to execute the limit warning
function for the corresponding input. Bits 00 through 07
correspond to inputs 1 through 8.
0: Limit warning function won't be executed.
1: Limit warning function will be executed.
Refer to 2-3-8 Limit Warning Function for more details.
The scaling data (upper and lower limits) is set in BCD (0000
to 9999), using two words for each input. Set the lower limit
in the first of the two words and the upper limit in the second,
and make sure that the lower limit is smaller than the upper
limit.
Refer to 2-3-5 Scaling Function for more details.
