Using DeviceLogix™
Introduction DeviceLogix is a stand-alone Boolean program which resides within the E3 Plus
Overload Relay. RS NetWorx for DeviceNet is required to program the device;
however, since the program is embedded in the E3 Plus software, no additional
module is required to use this technology. It is important to note that the
DeviceLogix program will only run if the logic has been enabled, which can be
done within the Logic Editor of RSNetWorx for DeviceNet or the DeviceNet
Configuration Terminal (Cat. No. 193-DNCT).
In addition to executing specific Boolean logic, DeviceLogix can also be used to
provide specific output performance under specific communication or network
conditions. This can be accomplished by properly configuring
Comm Override
and Network Override parameters.
Comm Override. The configuration of the Comm Override parameter
defines whether or not DeviceLogix controls the E3 Plus outputs when
either a Comm Fault (lack of I/O connection) or Comm Idle (Master not
in Run mode) condition exists. If DeviceLogix is enabled but
Comm
Override is disabled (default), the operation of the E3 Plus outputs will be
controlled by the DeviceNet Fault State, Fault Value, Idle State, and Idle
Value parameters if a Comm Fault or Comm Idle condition occurs. If
DeviceLogix and
Comm Override are both enabled, the E3 Plus outputs are
controlled by the DeviceLogix program, regardless of the Comm Fault or
Comm Idle state. If DeviceLogix is not enabled, the outputs will be
controlled by the DeviceNet Fault/Idle State/Value parameters if a Comm
Fault or Comm Idle condition occurs – regardless of the
Comm Override
configuration. If DeviceLogix is transitioned from enable to disable, the
outputs will immediately go to the programmed DeviceNet Idle
State/Value.
Network Override. The configuration of the Network Override
parameter defines whether or not DeviceLogix controls the E3 Plus
outputs when a network fault, such as a duplicate Mac ID or bus off
condition, exists. If DeviceLogix is enabled but
Network Override is
disabled (default), the operation of the E3 Plus outputs will be controlled
by the DeviceNet Fault State and Fault Value parameters if a network fault
occurs. If DeviceLogix and
Network Override are both enabled, the E3
Plus outputs are controlled by the DeviceLogix program, regardless of the
network status. If DeviceLogix is not enabled, the outputs will be
controlled by the DeviceNet Fault/Idle State/Value parameters if a Comm
Fault condition occurs – regardless of the
Network Override configuration.
If DeviceLogix is transitioned from enable to disable, the outputs will
immediately go to the programmed DeviceNet Idle State/Value.
