Figure 337: Direct inputs configuration settings
The following settings are available all direct inputs. The settings outlined are for direct
input 1.
Direct Input 1 Device ID
Range: 0 to 16 in steps of 1
Default: 0
This setting represents the source of the direct input. The specified direct input is driven
by the device identified here.
Direct Input 1 Bit Number
Range: 0 to 96 in steps of 1
Default: 0
This setting specifies the bit number to extract the state for this direct input. The
corresponding direct input is driven by the bit identified here. This setting also
corresponds to the direct output number of the sending device.
Direct Input 1 Default State
Range: On, Off, Latest/On, Latest/Off
Default: Off
This setting represents the state of the direct input when the associated direct device is
offline. The following choices are available:
– A value of "On" defaults the input to logic 1
– A value of "Off" defaults the input to logic 0
– A value of "Latest/On" freezes the input in case of lost communications. If the
latest state is not known (such as after relay power-up but before the first
communication exchange), the input defaults to logic 1. When communication
resumes, the input becomes fully operational.
– A value of "Latest/Off" freezes the input in case of lost communications. If the
latest state is not known (such as after relay power-up but before the first
communication exchange), the input defaults to logic 0. When communication
resumes, the input becomes fully operational.
Direct Input 1 Events
Range: Enabled, Disabled
Default: Disabled
This setting enables and disables the logging of direct input events in the sequence of
events recorder.
