Configure Digital Output Board
1) Select the board
2) Select the DXPDO16 tab.
3) Enter the following data.

Refresh Interval - Enter a value in the range 0 - 10000ms. This is the
maximum time allowed between transmissions of the output data.
Note: Data will be sent immediately following any change of output state. If a value
of zero is specified in this field then data will be refreshed every application scan
regardless of output state change.
The Refresh Interval should be calculated to deliver at least two updates within
the Refresh Timeout of the corresponding Input board, under worst case
conditions. A Refresh Timeout which is too short for the network size and
complexity will make it impossible to deliver fresh data often enough.
The setting for the Refresh Interval should be less than:
(Input board Refresh Timeout - Worst case Delivery Delay) / 2
The Worst Case Delivery Delay is:
Refresh Timeout (on DXPNC40 control board) + Scan time of this
controller + Scan time of receiving controller + 50ms
Wire the Digital Output Channel Data Variables
The digital output boards send digital data to the corresponding digital input boards on
the peer network.
1) Select the Data Variables tab.
