Digital I/O - MERRICK Genetix Safety, Installation, Operation And Maintenance Manual

Digital I/O

(Main Menu > Advanced Setup > Digital I/O)
This menu allows you to map the physical Digital Inputs and Digital Outputs to
specific logical functions, and to set certain properties for those IO. Physical inputs
are those that exist on the installed hardware. Physical inputs accept digital
information (such as contact closures) from external sources, and physical outputs
present similar information. The exact number of physical IO points and their form
depends on the installed hardware and the Configuration settings (see Main Menu >
Advanced Setup > Configuration).
Logical inputs are events that occur within the Genetix controller that typically cause
some action to take place. An example of a Logical input for a belt feeder would be
"Run Permission", which is required to make the feeder run. For this permission to
come from an outside source, this Logical input must be mapped to a Physical input,
and then that physical input connected to the external source.
Logical outputs are events that happen within the Genetix controller that are usually
the result of some action or process. An example of a Logical output for a belt feeder
would be "Running", which indicates that the belt is actually moving. For an outside
source to be informed of this event, this Logical output must be mapped to a Physical
output, and then the Physical output connected to the outside source.
Note: Mapping of Digital I/O and settings will normally take place at the Merrick
factory based on your specific requirements and wiring details. Changes should be
made carefully, as there is generally external equipment involved that may start, stop,
open, close, etc. unexpectedly. No changes should be made unless all equipment is
secure and no personnel are at risk.
If you have any doubts about this process, contact the Merrick Customer Service
department for assistance.
When you select "Digital I/O" you will be presented with another menu as follows:
Inputs...
Outputs...
Warnings/Faults...
Forces...
Inverted IO...
Inputs
This menu item allows you to map the Logical Inputs to the available physical
inputs. One Physical input may be mapped to multiple Logical inputs, allowing one
external physical event to trigger many internal logical events.
Selecting "Inputs" will present you with a list of all the current Logical Inputs, along
with the Physical input they are currently mapped to, if any.
