Network Analogue Input
The network analogue input block can be used to receive analogue values sent from a Data Manager. Once the controller is logged onto a Data
Manager, Data Builder programs running within the Data Manager can be used to map analogue values to the controller. Refer to the Data
Manager Data Builder user guide for further details.
Output -
Outputs the analogue network value at any given time from the network source (Data Manager Data Builder
program).
Refresh Timeout
–
This output will go true when communications are lost from the network source and the refresh timeout has
expired. The refresh timeout value can be changed by right-clicking on the background and selecting settings.
Note if communication
s are lost and the “Output” is e.g. “On” then it will remain “On” until comm’s are restored.

program.

A simple Data Builder PLC program, running on a Data Manager, is shown on the left. The
temperature of a room is being measured from probe 1 on the Data Managers analogue
input board and is being mapped to an analog output. By right-
clicking on the “Analog
Output” block, in the Data Manager TDB program, the following window on the left is shown.
This block has to be configured so that values can be sent to a Mercury Intuitive TDB
controller.

This will be set to
“Network”
Device -
Enter the controller name as it appears in the Data Manager device list.

The box opposite will appear in work space.
Change the Refresh timeout to the desired time.
If communications between the Mercury 2 TDB
controller and Data Manager are lost then the
Refresh Timeout output on the Network Analogue
Input and Network Digital Input will come on after this
time expires. This will remain on till comms are
restored
