5506 Analog Input Module
Description
The ain5506 I/O module is comprised of two different types of I/O channels. The
SCADAPack 5506 I/O hardware contains eight analog inputs and eight digital inputs. Each
of these types of I/O is represented as a sub module in the ain5506 I/O module. These sub
modules are named AIN for analog input I/O channels and DIN for digital input I/O channels.
The ain5506 I/O module provides eight analog inputs from a 5506 Analog Input module. A
maximum of sixteen 5506 analog input modules may be installed on the I/O bus. The 5506
Analog Input module can operate in Native mode or in 5501 Emulation Mode. The operating
mode is determined via a DIP switch on the 5506 Analog Input. Refer to the Control
Microsystems Hardware Manual for details on the DIP switch settings for the module.
When using the 5506 Analog Input module in 5501 Emulation mode the ain5501 module is
used in the I/O Connection. See the ain5501 section if the module is to be used in 5501
Emulation mode.
5506 native mode provides enhanced capability over the 5501 emulation mode. The
module operates in native mode if the 5501 Emulation DIP switch is open.
Each input is individually configurable for 0-5V, 1-5V, 0-20mA, or 4-20mA operation.
Converted analog input data is returned as a signed 15-bit value, providing 8 times more
resolution than in 5501 mode. Negative values are possible, for example if a 4-20mA is
open loop.
The module returns status information for each analog input indicating if the analog input
is in or out of range for the defined signal type.
All inputs have a configurable filter rate.
The input-scanning rate is software configurable to 50 or 60 hertz.
AIN Sub Module
The AIN sub-module provides eight I/O channels for the analog input data from the
SCADAPack 5506 I/O hardware. Data for each of the eight 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 5506 I/O hardware.
In addition to the eight I/O channels the AIN sub-module provides I/O Board parameters that
include module address, the type of analog signal, filtering used by all analog inputs and the
scan frequency.
The module_address parameter defines the module address of the ain5506 I/O module.
The address on the module is selected via dipswitches on the module. A maximum of
sixteen SCADAPack 5506 I/O type modules may be added to a system.
To set the module address, click the module address icon and then select the set /
channel parameter command from the Edit menu. The I/O Board parameter dialog is
opened as shown below.
