ASSIGN

ASSIGN

Assign creates a variable in memory and uncoditionally assigns to it the value present at component input pin.

The associated variable name is specified in the REFERENCE parameter. LadderWORK ARM software handles integer unsigned 16/32 bits variables.As written in IEC / CEI 1131-3 specification, we suggest, for this kind of variable, the use of the standard %MW prefix which means a memory word variable. When a variable is created using ASSIGN it is public to the entire net.

It is possible to read the value assigned by an ASSIGN object using the READVAR device.

ASSIGN transfer without changes the value present on its input pin to the output pin.
