Filter (sec)
Analog inputs for voltage and current
measurement can be filtered to remove the
effects of noise on the input. The filter time is
the time for the measured value to shift by 0.632
(1-e
-1
) of the changed value.
Measured(t) = input × {1−e
−t/filter
}
Set Point
Configuration
Each analog input is associated with a digital
input point that acts as a set point to show the
status of the analog input. Refer to Table 1 for
detail of how the setpoints operate
Lower/Upper Setpointe:
Configure the set
points with the desired low and high measured
values (mA, V, or Hz).
Inverte:
Check this to invert the state of the
digital set-point. Clear this to set direct mode.
Windowe:
Check this to set windowed mode for
the set point. Clear this to have the set-point
operate in hysteresis mode.

Configuring the Digital Inputse:
You can configure the behavior of
the digital inputs to control Debounce operation on these inputs. Set
the debounce time to the desired delay. The physical digital input
must remain changed for the configured amount of time before a
change is registered and the internal register is updated with the
new value. This allows the device to ignore inputs that are a result of
noise or bouncing contacts.

Save Changese:
Clicking this button saves changes to non-volatile
storage. Changes don’t take effect until the device has been
restarted. If you plan to make changes to multiple pages, use this
button before navigating to another page.
Save Change and Resete:
Clicking this button immediately applies
the changes on you have made by saving the new configuration to
non-volatile storage, then forcing the device to reset immediately.
Once the device has booted, the new changes will be in effect.
Failsafe configuration
You use the failsafe configuration to set up initial values for registers
and to configure how the register should behave if it doesn’t get
refreshed within a safety window of time. Failsafe configuration
also allows you to configure the device to reboot if it reaches an
unexpected state.
otee:
N
You normally don’t use the failsafe configuration for physical Inputs or
outputs. For physical outputs, you can configure the failsafe behavior in the
I/O Configuration screens.
Fail Safe Blockse:
You use this configuration to set up the behavior
of blocks of registers that you want to intialise to a certain status,
or if you want to have them go to a safe value in the case that
communication is lost.
The default behavior for registers without a fail-safe configuration
is to intialise the register to Zero (or Off) and to have no fail-safe
timeout configured.
Fail-Safe configuration can set a register to an “Invalid” state.
In this state, the register will appear to be not present. Modbus
polls covering this address will return an “Invalid Address” error, and
Modbus master mappings sending this address will not activate.
The Invalid state is cleared once a value is written to the register.
Add/Insert/
Delete Entry
Use these buttons to set up your table with one
entry for each block of I/O that you want to set
up. The setup will be the same for each item in
one block.
First Register
This is the address of the first register in the block.
Count
This is the number of registers in the block (the
registers are always in a contiguous block).
Timeout (s)
The fail-safe time out to use for this block.
Set the timeout to Zero to disable the fail-safe
timeout.
Initialize at Start
Check this if you want to initialize the register at
startup. Normally this will be checked to initialize
the register.
otee:
N
If you clear this checkbox, then at startup the
register state will be “Invalid”. In this state, the register
will have no valid value until it has its value written
through Modbus or WIB message protocol, or through
the I/O Diagnostics page.
Startup Value
If you checked “Initialize at start”, then the
register will be initialized with this value when
the unit is started.
Invalidate on Fail
Check this box if you want to set the register
state to “Invalid” when the fail-safe timer
expires. If you want to set the register to a
particular value, then uncheck this box and enter
a value for “Fail Value”.
Fail Value
This is the value that you want the register
to have if the fail-safe timer expires. This will
normally be a special value that indicates a
failure state to your process.
Fail Safe Reboote:
You can use this configuration to re-start the
module if it loses communication for a long time, which could the
the result of a module software error that may be recovered by a
reboot. To use this feature, you need to set up a register to indicate
that the system is operating correctly. If this register stays cleared
(Zero or Off) for the configured time, then the module will restart.
Reboot Register
The register to use to indicate the system is healthy.
Reboot Timeout
(sec)
The number of seconds to wait for the system
health indication to return before restarting the
module.
