Chapter 9 DeviceLogix™ Functionality
Communication Fault Mode and Communication Idle Mode parameters if a
communication fault or communication idle condition occurs.
If DeviceLogix functionality and Communication Fault & Idle Override are both
enabled, the E300 outputs relays are controlled by the DeviceLogix program
regardless of the Communication Fault Mode or Communication Idle Mode.
If DeviceLogix functionality is not enabled, the E300 output relays are controlled
by the Communication Fault Mode or Communication Idle Mode parameters if
a communication fault or communication idle condition occurs – regardless of
the override configuration of the Communication Fault & Idle Override
parameter.
If DeviceLogix functionality is transitioned from enable to disable, the E300
output relays immediately go to the appropriate Communication Fault Mode or
Communication Idle Mode.
Network Fault Override (Parameter 347)
Network Fault Override (Parameter 347) defines whether or not DeviceLogix
functionality controls the E300 output relays when either a duplicate node
address is detected or a network bus off condition exists.
Table 561 - Network Fault Override (Parameter 347)
If DeviceLogix functionality is enabled but Network Fault is disabled, the
operation of the E300 output relays is controlled by the Communication Fault
Mode parameters if a network fault condition occurs.
If DeviceLogix functionality and Network Fault are both enabled, the E300
outputs relays are controlled by the DeviceLogix program regardless of the
Communication Fault Mode.
If DeviceLogix functionality is not enabled, the E300 output relays are controlled
by the Communication Fault Mode parameters if a network fault condition
occurs – regardless of the Network Fault Override configuration.
If DeviceLogix functionality is transitioned from enable to disable, the E300
output relays immediately go to the appropriate Communication Fault Mode.
DeviceLogix Programming
DeviceLogix functionality has many applications and the implementation is only
limited to the imagination of the programmer. Keep in mind that the application
of DeviceLogix functionality is only designed to handle simple logic routines.
Program DeviceLogix functionality by using simple Boolean math operators,
such as AND, OR, NOT, timers, counters, and latches. Decision making is made
