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.
