The HMISCUxB5 HMI controllers have embedded analog I/O:
o2 analog inputs
o2 analog outputs
For information about the technical characteristics of the analog I/O, refer to the Hardware Guide.

Analog I/O Configuration Window
This window allows you to configure the analog I/O:
NOTE: The parameter is unavailable if the selection displays as gray in color.
NOTE: Embedded analog I/Os are always physically updated by the MAST task.
To configure the HMI SCU, select the I/O Configuration tab.
The table describes the analog parameters configuration:

If you have physically wired the analog channel for a voltage signal and you configure the channel for a current signal in SoMachine, you may damage the analog circuit.
|
NOTICE |
|
INOPERABLE EQUIPMENT |
|
Verify that the physical wiring of the analog circuit is compatible with the software configuration for the analog channel. |
|
Failure to follow these instructions can result in equipment damage. |
Analog to Digital Conversion Rate
Analog-to-digital conversion rate for data acquisition is made using the converter hardware. All analog I/O that are configured are converted every 2 ms.
Variables can be defined and named in the Analog I/O Mapping tab. Additional information such as topological addressing is also provided in this tab.
This window shows the Analog I/O Mapping tab:
