Modifying Instructions
In the previous example you modified a rung by adding an instruction to the
rung. Another function available in the HHT is the ability to modify
instructions. Instructions may be edited by changing the address and/or
changing the type of instruction. The following examples show you how to
do both.
Changing the Address of an Instruction
Change the address of the second examine if closed instruction, in the first
rung (rung 0) of the program, from I:1.0/2 to I:1.0/1. The new rung should
appear as follows:
