B. For instance, a device configured at %AI0001 on Bus A must be
configured at %AI (1+AI_OFST) on Bus B.
This parameter applies to devices that contain discrete
inputs. It is the starting reference assignment for the device
installed at Serial Bus Address nn.
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.

This parameter applies to devices that contain analog
inputs. It is the starting reference assignment for the device
installed at Serial Bus Address nn.
This parameter applies to devices that contain analog
inputs. It is the number of inputs (i.e., length) associated

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.
Devices that contain outputs must be configured so that the dual mapping routine can post
loss-of-device or addition-of-device messages. Also, the device status (i.e., the presence on
either Bus A or Bus B) is shared between the Primary and Secondary PLCs for the purpose of
Automatic Role Switching (if enabled).
