sp330
SCADAPack 330 I/O
Description
The sp330 I/O module is comprised of three different types of I/O channels. The
SCADAPack 330 I/O hardware contains three analog inputs, one digital input and two digital
outputs. Each of these types of I/O is represented as a sub module in the sp330 I/O module.
These sub modules are named AIN for analog input I/O channels, DIN for digital input I/O
channels and DOUT for digital output I/O channels.
The AIN sub-module provides three I/O channels for the counter input data from the
SCADAPack 330 I/O hardware. Data for each of the three 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 330 I/O hardware.
 Analog input channel 0 is for counter input 0. This is a 32 bit value with automatic
rollover.
 Analog input channel 1 is for counter input 1. This is a 32 bit value with automatic
rollover.
 Analog input channel 2 is for counter input 2. This is a 32 bit value with automatic
rollover.
The DIN sub-module provides one I/O channel for the digital input data from the
SCADAPack 330 I/O hardware.
 Digital input channel 0 is the status of COM3 HMI power.
0 = 5V at pin 1 of connector P7 (COM3) is off.
1 = 5V at pin 1 of connector P7 (COM3) is on.
The DOUT sub-module module provides two I/O channels for the digital outputs of the
SCADAPack 330 I/O hardware.
 Digital output channel 0 controls the USB STAT led.
0 = USB STAT led off
1 = USB STAT led on
 Digital output channel 1 controls the COM3 HMI power.
0 = 5V at pin 1 of connector P7 (COM3) is off.
1 = 5V at pin 1 of connector P7 (COM3) is on.
Data for each of the I/O channels may be connected to user-defined variables with the I/O
connection editor. The SCADAPack 330 I/O hardware digital outputs are updated
continuously with data read from the variables.
