evaluating a rung. These stack rules are checked when the editing of a rung is completed. If the stack
operations are not balanced when this happens, the Model 880 will issue an error message.
Operate Menu
There are 2 options under the Operate Menu. These are used to suspend/resume the operation of
the I/O program. The use of turning off the operation of the I/O program is in case something goes
wrong. You can shut off the program while editing changes so relays are not turning on and off before the
program is completely entered.
Stopping The I/O Program
Use caution when causing the I/O program to stop running. This should be a temporary condition
used for entering or modifying your program only. If someone else does not know the I/O program is
stopped and tries to run the instrument, the results can be serious. See figure x5.3 and OPR key definition
in section 5.11.
Memory Menu
Saving Your Program.
This provides you with the ability to save and recall your I/O program. If
you want to try something new with the I/O system, it is a good idea to save what
you have running before making major changes to the program. The Save option
will take the entire I/O program and store it in an alternative memory sector. The
Swap option will put the active I/O program into inactive status, and take what was
in inactive memory and make it active. Both programs (one in alternate memory and
one in active memory) are remembered when power is off. The I/O program check
sum (prefixed with the label ID=) also reflects which memory section is in use by it's
first character: A or B memory.
In addition to saving your program in memory, be sure to record it on a piece of paper also. If a
unit ever needs to be replaced, you will have to reprogram its I/O for your system requirements. See figure
5.10 and MEM key definition in section 5.11.
