 A scan_freq value of 0 synchronies the input scanning to 60Hz.
 A scan_freq value of 1 synchronies the input scanning to 50Hz.
 To set the scan_freq parameter, click the scan_freq icon and then select the set /
channel parameter command from the Edit menu. The I/O Board parameter dialog is
opened as shown below.
 Enter the scan frequency, 0 or 1, in the Value: entry field and click OK.
The aout_type parameter sets the analog output type for both optional analog output
channels.
 An aout_type value of 0 sets the output type for 0 to 20mA signals.
 An aout_type value of 1 sets the output type for 4 to 20mA signals.
 To set the aout_type parameter, click the aout_type icon and then select the set /
channel parameter command from the Edit menu. The I/O Board parameter dialog is
opened as shown below.
 Enter the analog output type, 0 or 1, in the Value: entry field and click OK.
AOUT Sub Module
The AOUT sub-module provides two I/O channels for the analog output data for the
SCADAPack sp5606 I/O hardware. Data for each of the I/O channels may be connected to
user-defined variables with the I/O connection editor. The SCADAPack 5606 I/O hardware
analog outputs are updated continuously with data read from the variables.
The aout_type parameter in the AIN Sub Module sets the analog output signal type for 0 to
20mA or 4 to 20mA.
DIN Sub Module
The DIN sub-module provides forty I/O channels for the digital input data from the
SCADAPack sp5606 I/O hardware. Data for each of the I/O channels may be connected to
user-defined variables with the I/O connection editor. Connected variables are updated
continuously with data from the SCADAPack 5606 I/O hardware.
The 5606 I/O Module provides thirty-two external digital inputs. These are externally wetted
inputs.
 Digital Input channels 0 to 31 return the digital input status for the 5606 I/O Module.
0 = contact open (led off).
1 = contact closed (led on).
