Name
You can enter a descriptive name for the input to help with configuration, or use the
default. The name can be up to 30 characters, including spaces.
Debounce Time
(Sec)
Debounce is the time which an input must stay stable before the module decides that
a change of state has occurred. If a digital input changes (on - off) and changes again
(off - on) in less than the debounce time, then the module will ignore both changes.
Default debounce time is 0.5 seconds.
Save and Activate
Changes
Save to non-volatile memory and restart to activate changes.
I/O Register Locations
There are over 5000 x 16-bit general purpose registers that are available for Modbus and are shared with both
Modbus client and server. This includes the onboard analog/digital input/output registers.
long with the physical DIO status, the internal I/O can be accessed by reading from or writing to the following
register locations. The register locations are structured into standard Modbus I/O types, and can be accessed
using the local onboard Modbus TCP server, Modbus serial master or an external Modbus master device.
The layout of the WI-MOD-xxx-E-5W I/O registers are summarized in the following table. Each register is internally
saved as a 16-bit unsigned integer value. A Modbus transaction may access the entire 16-bit value of any register,
or alternatively, the most significant bit of a register may be accessed as a discrete value. The main use for the
general purpose I/O registers is for intermediate storage
—for example, when transferring I/O from one Modbus
slave device to another. Also provided is the status of the on-board digital I/O, the status of the wireless link, and
any serial or TCP connections.
