towards Pin 12 selects ±10VDC. Each channel must be se

4 CONFIGURATION
Note: The status of the I/O can be monitored in Cscape Software.
Module Setup Tab
The Module Setup is used to configure the Analog
Inputs and Analog Outputs ±10V and ±20mA modes
and for applications where it is necessary to change the
default states or values of the outputs when the
controller (e.g., OCS100) enters idle/stop mode.
1. For Digital Outputs: The default turns the outputs
OFF when the controller enters idle/stop mode. By
selecting the Module Setup tab, each output can be set
to either turn ON, turn OFF or to hold the last state.
Generally, most applications use the default settings.
Warning: The default turns the digital outputs OFF
when the controller enters idle/stop mode. To avoid
injury of personnel or damages to equipment,
exercise extreme caution when changing the default
settings.
2. For Analog Outputs:
Mode: ±10V or ±20mA must be set for each channel. The
associated slide switch on the back of the module must
match the Cscape setting for each channel.
Idle: The default sets the output values to zero when the
controller enters idle/stop mode. By selecting the Module
Setup tab, each output can be set to a specific value or hold
the last value. Generally, most applications use the default
settings.
Warning: The default sets the output values to zero
when the controller enters idle/stop mode. To avoid
injury of personnel or damages to equipment, exercise
extreme caution when changing the default setting using
the Module Setup tab.
3. For Analog Inputs: :
Mode: ±10V or ±20mA must be set for each channel. The
associated slide switch on the back of the module must
match the Cscape setting for each channel.
Filter Constant: Sets the level of digital filtering according to
the following chart.
I/O Map Tab
The I/O Map describes which I/O registers are assigned.
The I/O Map is not
edited by the user.

Digital Filtering. The illustration above demonstrates the effect of digital filtering (set with Fillter
Constant) on module response to a temperature change.
5 ANALOG INPUT CONVERSION FACTOR
The following table describes how real-world inputs are scaled into the controller. Given a known input
current, the data value is configured by using the conversion factor from the table. The following formula
is used: Data = Input Current (mA) / Conversion Factor
Example: The user selects a current range of ±20mA:
1. The known input current is 14mA.
2. Using the table, the conversion factor for the current range of ±20mA is 0.000625.
3. To determine the data value, the formula is used:
Data = Input Current (mA) / Conversion Factor
22400 = 14mA / 0.000625

6 ANALOG CONVERSION OUTPUT FACTOR
The following table describes how program data values are scaled to real-world analog voltage outputs by
the module. Given a desired output current, the data value is converted by using the conversion factor
from the table. The following formula is used: Data = Output Current (mA) / Conversion Factor
Example: The user selects a current range of ±20mA:
1. The desired output current is 12mA.
2. Using the table, the conversion factor for the current range of ±20 mA is 0.000625.
3. To determine the data value, the formula is used:
Data = Output Current (mA) / Conversion Factor
19200 = 12mA / 0.000625

7 INSTALLATION / SAFETY
a. All applicable codes and standards should be followed in the installation of this product.
b. Shielded, twisted-pair wiring should be used for best performance (Analog I/O).
c. Shields may be terminated at the module terminal strip.
d. In severe applications, shields should be tied directly to the ground block within the panel.
e. Use the following wire type or equivalent: Belden 8917, 16 AWG or larger for Digital I/O and Belden
8441 for Analog I/O.
For detailed installation information, refer to Mini Hardware Manual. A handy checklist
covers panel box layout requirements and minimum clearances.
