Configuration - DI-10
The DI-10 Module is a 16 channel Digital Input module with configurable Frequency or Pulse or Quadrature
counting and Sequence-of-Events recording. After the DI-10 module has been added to the IO modules list,
these options can be configured. Note: Sequence of Events is not supported when the DI-10 is used with a
PC-1 or CP-1 processor module.
Slot Address: (1 to 64) The slot address of the DI-10.
Channel Inversion: These tick boxes allow channel inversion to be configured for any input channel. The
All ON and All OFF buttons provide an easy way to select or de-select all the channels. By default, a high
voltage applied to a digital input channel will result in a logical 1 in the digital input register and the input LED
on the module to be set ON. A zero or low voltage level will result in a logical 0 in the digital input register,
and the input LED will be OFF. By configuring channel inversion, the situation is reversed, ie. a high voltage
results in a logical 0 and the LED is set OFF; a low voltage results in a logical 1 state and the LED is set ON.
Sequence-of-Events: These tick boxes allow Sequence Of Events (SOE) recording to be configured for any
input channel. The All ON and All OFF buttons provide an easy way to select or de-select all the channels.
When SOE is enabled, any change of state of the input channel (an event) is logged to 1 millisecond
accuracy. This event is automatically included in the Event Log List of the RTU. The DI-10 has a timer that is
automatically synchronised with the real-time clock of the processor module. Note: The DI-10 has an internal
buffer with enough space for 1000 event logs. This means that a DI-10 can cope with bursts of up to 1000
events at a time. Events are uploaded into the processor module at a maximum rate of 100 events per
second allowing the DI-10 to cope with events at a sustained rate of 100 events per second. Events are
stored in a circular buffer - which causes the oldest event to be overwritten with the newest event when the
buffer is full. Note: memory must be allocated for event logging for SOE to work. Please see the topic
Configuration - Memory, Event Logs.
