J. Polling the TCU - DFS Point and Modbus Registers
Pump Control Application by Module Letter and Point
The TCU Pump Control template consists of eight individual modules, including one for the integrated radio. The tables on
the following pages list the properties of each module contained in the template and provide a description of each point’s
function.
For those systems using the Modbus protocol, equivalent Modbus registers are also provided.
Note: Alarm states are listed for some but not all of the TCU’s I/O points. Those listed are common alarms, but any or all
configured telemetry points can be set to alarm in any desired state.
