5-2 Chapter 5: Configuration, Data, and Status Tags
Owner’s Guide 0300199-01 Rev. D
The following Global Module Settings and Channel-Specific Settings sections
allow custom configuration of the module. These tags can be found within the
CTR8_config controller tags.
[x] designates the channel number.
(C) designates the value may be changed during module operation
CountLimit[x] 0 - 16777215 FLOAT (C)
Designates the channel rollover value. The maximum value is 1677215 when
scaling is off. When scaling is applied the maximum value is 1677215/K*M.
Preset[x] 0 - 16777215 FLOAT (C)
Designates the channel preset value. Module begins counting at this value.
NOTE
IMPORTANT: This value cannot be greater than the rollover value. The
maximum value is 1677215 when scaling is off. When scaling is applied
the maximum value is 1677215/K*M.
RateSamplePeriod[x] 0-2000 INT
When using period/rate mode, set this value as a multiple of 10 ms between 0 and
2000. This becomes the integration time over which rate data is averaged.
OperationalMode[x] 0,1 INT
Designates channel operational mode:
• 0 = unidirectional counter mode (Up).
• 1 = bidirectional counter mode (Up / Down).
• 2 = encoder X1 mode.
• 3 = encoder X4 mode.
NOTE
Channels must be configured in pairs. (0,1) (2,3) (3,4) (4,5) (5,6) (6,7)
Input configurations determine how the 8 inputs cause the counter to
increment or decrement. The four available configurations are:
• Uni-Directional (up).
• Bi-Directional (up and down using two channels).
• X1 Quadrature Encoder.
• X4 Quadrature Encoder.
