Dual Bus Parameters
Figure 19: Dual Bus Parameters
BUS.DEF_TO The Default Timer Preset establishes the time interval (in milliseconds) during which
inputs are frozen while a device is missing from Bus A AND from Bus B.
BUS.DEF_HLS This parameter (a Boolean) determines the behavior of a missing device:
• If the parameter is set to 0, the inputs for that device will default to OFF or 0
after the Default Timer expires.
• If the parameter is set to 1, the inputs for that device will be frozen in their last
state until the device is reattached to either Bus A or Bus B.
BUS.DI_OFST This applies to discrete inputs. It is the reference offset between a discrete input
configured on Bus A and the alternate address on Bus B. For instance, a device
configured at %I0001 on Bus A must be configured at %I (1+DI_OFST) on Bus B.
The offset must be in multiples of 8 (i.e., on a byte boundary).
BUS.AI_OFST This applies to analog inputs. It is the reference offset between an analog input
configured on Bus A and the alternate address on Bus B. For instance, a device
configured at %AI0001 on Bus A must be configured at %AI (1+AI_OFST) on Bus B.

BUS.Devices[nn].DI_Add This parameter applies to devices that contain discrete inputs. It is the starting
reference assignment for the device installed at Serial Bus Address nn.
BUS.Devices[nn].DI_Len This parameter applies to devices that contain discrete inputs. It is the number of
inputs (i.e., length) associated with the device installed at Serial Bus Address nn.
BUS.Devices[nn].DQ_Add This parameter applies to devices that contain discrete outputs. It is the starting
reference assignment for the device installed at Serial Bus Address nn.
BUS.Devices[nn].DQ_Len This parameter applies to devices that contain discrete outputs. It is the number of
outputs (i.e., length) associated with the device installed at Serial Bus Address nn.
BUS.Devices[nn].AI_Add This parameter applies to devices that contain analog inputs. It is the starting
reference assignment for the device installed at Serial Bus Address nn.
BUS.Devices[nn].AI_Len This parameter applies to devices that contain analog inputs. It is the number of
inputs (i.e., length) associated with the device installed at Serial Bus Address nn.
BUS.Devices[nn].AQ_Add This parameter applies to devices that contain analog outputs. It is the starting
reference assignment for the device installed at Serial Bus Address nn.
BUS.Devices[nn].AQ_Len This parameter applies to devices that contain analog outputs. It is the number of
outputs (i.e., length) associated with the device installed at Serial Bus Address nn.
