Modexfer
This function block enables the mode to be changed on Unidrive or Unidrive SP.
|
Note: |
If the mode change is successful, the drive and option modules will be reset causing the DPL program to restart. Also, the drive parameters will be restored to defaults when the mode change occurs. |

MOVE
This block assigns its input to its output.
Example
The above example will set parameter #18.11 to 100 when parameter #18.31 is set to 1.
Target/ Language Restrictions

Mpot - Motorised Pot
MPOT is a ramp generator used to decrement or increment a value within a limited area.
Arguments
PSet% - 32-bit signed
The Preset value to be applied to the output when PEn% is set.
PEn%
If set to 1, Q% is set to the value of PSet%. If cleared to 0, the output ramps (depending on the values of Dec% and Inc%).
Dec%
If set to 1 and both PEn% and Inc% are clear, Q% decrements.
Inc%
If set to 1 and both PEn% and Dec% are clear, Q% increments.
Rate%
The required ramp rate in units per second. this value is scaled by 3 decimal places, i.e. 1000 = 1.000.
Max%
The high limit for the ramp output.
Min%
The low limit for the ramp output.
Return Values
Q%
The ramp output.

MULDIV
This is a mathematical function which multiples two 32-bit values to get a 64-bit intermediate result and then divides the intermediate by a 32-bit value to get a final result.
Arguments
M1%, M2%
The values to be multiplied.
DIV%
The value by which (M1% * M2%) is to be divided.
Return Values
Q%
The result.
Example
Target/ Language Restrictions
None.

Muldivrm
This is a mathematical function which multiples two 32-bit values to get a 64-bit intermediate result and then divides the intermediate by a 32-bit value to get a final result and remainder.
Arguments
M1%, M2%
The values to be multiplied.
DIV%
The value by which (M1% * M2%) is to be divided.
Return Values
Quot%
The result of (M1% * M2%) / DIV%.
Rem%
The remainder of (M1% * M2%) / DIV%.
Example
Target/ Language Restrictions
None.

IMux / fMux / iMux2 / fMux2 / iMux8 - Multiplexers
This is a family of function blocks which multiplex one of a set of inputs into a single output. A number of multiplexer blocks are supplied which accept different numbers of inputs and integer or floating-point inputs.
Arguments
IN0% to IN7%, IN0 to IN7
The values to be multiplexed.
Select%
The input selected to be set in the output - 0 selects input 0, 1 input 1 etc. If the Select% value is out of range, the output is cleared to 0.
Return Values
Q/ Q%
The value of the selected input OR 0 if the Select% input value is out of range (< 0 or > number of inputs - 1).
Example
Target/ Language Restrictions
None.
