P-NET SWNo. 4: Output2
This register may be used to control Output2, and holds information about the current state
of the output.
If an automatic function is selected for Output2, only this function can control the state of
Output2.
Output2 = 00
=>
Output2 = 01
=>
P-NET SWNo. 5: Output3
This register may be used to control Output3, and holds information about the current state
of the output when it is used as a simple digital output.
If an automatic function is selected for Output3, only this function can control the state of
Output3. In this case, the state of Output3 will change rapidly, depending on the output
pulse frequency or current output value and there is not much to be gained by reading the
state.
Output3 = 00
=>
Output3 = 01
=>
P-NET SWNo. 6: Input1
This register holds information about the current state of Input1. Input1 cannot be controlled
internally.
Input1 OFF
=>
Input1 ON
=>
P-NET SWNo. 7: BatchStart
When the Output2 function is set to batch control, batching is started either by activating
Input1 or by inserting 01 in this register. The register is reset immediately, the volume
counter Volume2 is cleared, Output2 will turn ON and dosing starts.

P-NET SWNo. 11: Flow
This register can show the current Flow rate for the liquid in the Flow Transmitter. The Flow
rate is an averaged value, where the time constant for the digital filter and the flow rate in
unit/min. or unit/hour can be selected in the Code3 register. The time constant for the filter
can be chosen to be one of four values in the interval between approx. 0.15 sec. and
approx. 10 sec. Reverse flow (relative to the arrow on the meter head) can be set to 0, as
well as Flow rates smaller than 0.2% of max. flow can be set to 0 (selected in Code3).
