Connections
IN1, IN2 and IN3: boolean value
OUT: 16 bit integer (packed boolean)
ParRead
Parameter function
Illustration
Operation
OUT shows the value of a parameter. IN1 defines the group. IN2 defines the index.
Example:
Reading
AccTime1 (22.01):
IN1 = 22 and IN2 = 01
Connections
IN1: 16 bit integer (15 bits + sign); group
IN2:
16 bit integer (15 bits + sign); index
IN3:
not used
OUT: 16 bit integer (15 bits + sign); parameter value
ParWrite
Parameter function
Illustration
Operation
Value of IN1 is written into a parameter defined by IN2 as group * 100 + index, e.g.
MainCtrlWord (7.01)
== 701. The block is activated with a change of IN1.
IN3 determines if the
value is saved in the flash.
Attention:
Cyclic saving of values in the flas
h will damage it! Do not set IN3 constantly to true!
OUT gives the error code, if parameter access is denied.
Example
s:
Set
AccTime1 (22.01) = 150, not saving into flash:
IN1 = 150, desired value
, this must be a defined as a constant
IN2 = 2201, this must
be a defined as a constant
IN3 = false
Set SpeedRef (23.01) = by means of AI1, not saving into flash:
