The module can detect open and short-circuit field cables when a linemonitoring device is installed at the field switch. Line monitoring functions

are independently configured for each input channel.

The module provides on-board sequence of events (SOE) reporting with a

resolution of 1ms. A change of state triggers an SOE entry. States are

determined by voltage thresholds that can be configured on a per channel

basis.

Status LEDs

There are input channel status LEDs on the module front panel, one for each

field input. The input status LED mode is dependent upon the voltage level

of the field I/O signal. Each field input voltage is measured and compared to

six threshold levels (four configurable and two fixed) which produce seven

threshold bands, as described in Section 8. Each threshold band can be

defined to have a particular indicator mode: off, green, red, flashing green,

or flashing red.

The configurable voltage thresholds and LED modes allow users to

customize the input measurement and status indications to suit individual

application requirements. Without customization, the default indicator

modes are suitable for digital inputs without line monitoring and are:
