Cmp - Comparison Block
Compares two integer numbers and returns two boolean outputs representing the relationship between the two input numbers and also returns the higher and lower of the two input values.
Arguments
Val1%, Val2%
The two values to be compared.
Return Values
GT%
This value is set to 1 if Val1% > Val2%.
EQ%
This value is set to 1 if Val1% is equal to Val2%.
MIN%
This value is set to to the smaller of Val1% and Val2%.
MAX%
This value is set to to the larger of Val1% and Val2%.
Target/ Language Restrictions
None.

Condparw - Conditional Parameter Write
This function block writes to a given drive parameter when the control input is set.
Arguments
Ctrl%
A value will only be written to a parameter when Ctrl% has the value 1. If Ctrl% is 0, the parameter will not be written.
Param%
The parameter to be written in MMPP form, e.g. 1820 means write to parameter #18.20.
Val%
The value to be written to the parameter.
DPos%
The number of decimal places in Val%, e.g. to write the value 1.23 to a parameter, set Val% to 123 and DPos to 2.
An integer parameter write (#INT) can be performed by setting DPos to -1.
Return Values
Q%

Meaning |
|
0 |
Operation failed OR Ctrl% was 0. |
|
1 |
Operation succeeded. |
Example
The main purpose of this block is to avoid the use of conditional jumps within a LD or FB diagram. By setting or clearing the Ctrl% input, the user can control whether or not a value is written to a parameter. This is demonstrated in the following LD/ FB diagram. Depending on whether parameter #20.20 has a value greater than 1000, the value 100 or -100 is written to parameter #18.20.
Target/ Language Restrictions
None.
