Operator: Content Operator
The operator is an extension of the IEC 61131-3 standard.
The operator allows for dereferencing a pointer. You append the operator as ^ to the pointer identifier.
Caution
When using pointers to addresses, note that applying an online change can shift the contents of addresses.
