Configuring POINT I/O and ArmorPOINT I/O DeviceLogix modules using RSNetworx for DeviceNet 51
DLX Dependent
Mode This parameter allows the logic in the module to be enabled or
disabled according to the I/O connection status or the state of the
owning processor. The default is disabled.
If Dependent Mode is enabled, the DeviceLogix program will be
disabled when the owning processor is in program mode. When the
processor transitions to RUN, the logic will automatically be enabled.
DLX Fault
Override When an output is being locally controlled, its state is either
controlled by the DeviceLogix program or by the Fault/Idle states.
Enabling this parameter allows the local logic to override the
Fault/Idle states in the event of a communication fault or transition to
Idle (Program) state. When this parameter is disabled (default) and a
communication fault occurs or when in Idle (Program) state, all
outputs, including those that are locally controlled, will go to the
Fault/Idle states. Enabling this parameter and using the "Network
Fault" status bit (Bus-off or Dup Mac Error) or COS/Cyclic Cnxn
Idle/Fault bits in the DeviceLogix program, a controlled stop or
maintenance of a machine state can be achieved when
communication is lost with a master.
Auto Produce
Assembly When the Auto produce parameter is enabled, this parameter selects
which assembly to produce:
000: 20-byte assembly (default)
004: 1-byte assembly
101: 20-byte assembly
111: 8-byte assembly
For details on the contents of the assembly, see I/O Data Assembly
Maps in Chapter 4 .
For the list of I/O tags, see I/O Tags in Chapter 5 .
The 20-byte assembly contains all the data. The 8-byte assembly can
be produced in one packet (non-fragmented).
Auto Produce EPR When the Auto Produce parameter is enabled, this parameter sets the
Expected Packet Rate. The units are milliseconds (ms). The default is
1000 ms. The maximum is 65535 ms and the minimum is 0 ms.
When Auto Produce is enabled, the module produces data at every
change of state (COS) or when the EPR timer expires.
Auto Produce PIT When the Auto Produce parameter is enabled, this parameter sets the
Product Inhibit Time. The units are milliseconds (ms). The default is
1 ms. The maximum is 65535 ms, and the minimum is 0 ms.
If a Change of State occurs and the PIT has not expired, the message
will wait until the PIT has expired. This can be used to prevent one
module from using all the available network bandwidth.
