The procedure for online editing<\/strong> is very similar in the PLC-5, SLC-500, and ControlLogix.\u00a0 There are five basic steps in performing an online edit:<\/p>\n

1) Start Rung Edits (Place the rung into edit mode)<\/p>\n

2) Make your changes to the rung<\/p>\n

3) Accept Edits (Send the edits to the processor)<\/p>\n

4) Test Edits (Ensure your edits work how you want them to work)<\/p>\n

5) Assemble Edits (Removes the old rung, and remove the editing markers)<\/p>\n

Note:\u00a0 The ControlLogix processor allows you to accept edits to a single rung or all rungs in the program…\u00a0 Modern versions of RSLogix 5000 also have a “Finalize” option which allows you to Accept, Test, and Assemble all in one step!)<\/em><\/strong><\/p>\n

These steps are simple, but there are a few rules:<\/p>\n

\u2022 You cannot change the data type of existing tags. If you create a new tag with the wrong data type,
\nyou must delete the tag, and declare it again.
\n\u2022 You cannot make an on line edit if the key switch is in Run Mode.
\n\u2022 You do not need to perform an on line edit to directly change a value in the data table such as the
\npreset of a timer or counter.
\n\u2022 If the processor is in program mode, you do not need to test and assemble after accepting.
\n\u2022 If the processor is in program mode, and a rung is deleted, there is no warning.<\/p>\n

Note:\u00a0 These may vary depending on which processor you are using, and the processor version.<\/strong><\/em><\/p>\n

Let’s walk through the 5 step procedure:
\nLook at the rung below. Our objective is to transfer control of the output to LocalSwitch.6. If you
\nclick on bit LocalSwitch.7 and attempt to make a change, nothing happens.<\/p>\n

\"InitialRung\"<\/a><\/p>\n

Step 1) Start Rung Edits<\/strong>
\nThe first step is to put the rung into edit mode. There are several ways this can be done:
\n\u2022 Double click the rung number
\n\u2022 Right click the rung number and start rung edits
\n\u2022 From ‘Logic’ on the menu bar, click On line Edits, then start pending rung edits
\n\u2022 Click the start rung edit icon in the on line editing tool bar just above the ladder view<\/p>\n

\"step1a\"<\/a><\/p>\n

Notice that RSLogix made a copy of the rung for us to work with. By looking at the power rails, you
\ncan see the bottom rung is being executed by the processor, and the top rung is the one you need to
\nmake edits to. You will also notice the e (edit) or i (insert) and r (replace) in the margin are lower case.
\nThis means the edits are not in the processor yet. If you are adding new logic instead of modifying
\nexisting logic, this is the step where you add a new rung.<\/p>\n

\"step1b\"<\/a><\/p>\n

Step 2) Make Changes<\/strong>
\nNow that the rung is in edit mode, changes can be made.
\nIf you added a new rung in step #1, this is where you need to add your logic to the new rung.<\/p>\n

Be careful not to add any logic that will fault the processor or cause damage to personnel or equipment.<\/p>\n

Notice the i (insert) and r (replace) zones are in lower case. This means the changes are in RAM only,
\nand have not been sent to the processor.
\nIn this example, bit 7 is being changed to bit 6 on the input.<\/p>\n

\"step2a\"<\/a><\/p>\n

Step 3) Accept Edits<\/strong>
\nNow that your rung is set up as you need it, it’s time to send the edits to the processor. You can accept
\npending rung edits (This would just accept the rung you have selected), or you can accept pending
\nprogram edits (This would accept all the edits in the current program) There are several ways to
\nperform the next three steps.
\n\u2022 Right click the rung number, and accept edits
\n\u2022 Click Logic | On line Edits | Accept (rung or program edits) from the menu bar
\n\u2022 Click one of the Accept Edits icons in the on line editing tool bar as shown below<\/p>\n

\"step3a\"<\/a><\/p>\n

\"step3b\"<\/a><\/p>\n

Notice in the margin rung 1 is marked for insertion, and rung 2 is marked for removal. The I’s and R’s
\nare capitol because the edits are now in the processor. Look at the power rails. You can see the old
\nrung is still being executed by the processor.<\/p>\n

\"step3c\"<\/a><\/p>\n

You will also see that pending edits exist by looking at the on line tool bar.<\/p>\n

\"step3d\"<\/a><\/p>\n

Step 4) Test Edits<\/strong>
\nWhen you test edits, the new or modified rungs will become active. The old rungs will be left in the
\nprocessor until we are sure our new rungs are working properly. Be aware that if you change an output
\naddress, there might no longer be logic writing to that address. This means that you could abandon a
\nbit in the ON state.<\/p>\n

You can test your edits by doing one of the following actions:
\n1) Right click the rung number
\n2) Choose Logic | On line Edits | Test accepted program edits from the menu bar
\n3) Click the Test icon in the on line edit tool bar above your logic window.<\/p>\n

\"step4a\"<\/a><\/p>\n

If you are modifying an input type address you should also be careful. If the rung was previously true,
\nyou may want to make sure your new logic is also going to be true at the moment you accept, or the the
\noutput may shut off.<\/p>\n

Let’s test the edits, and you will notice the new rung(s) are active. If the edits do not work the way you
\nanticipated, you can un-test to revert to the old rung while you make other changes to the new rung.<\/p>\n

Notice the power rails:<\/p>\n

\"step4b\"<\/a><\/p>\n

Step 5) Assemble Edits<\/strong>
\nIf you logic is working properly, go ahead and assemble the edits. Assembling removes the old rung,
\nand the edit zone markers. After Assembling, you may want to save your work to the hard drive.<\/p>\n

You can assemble by using one of the following methods:
\n1) Right click the rung number, and choose accept edits (if available in your version)
\n2) Click Logic | On line Edits | Assemble accepted program edits from the menu bar.
\n3) Click the Assemble Edits icon in the on line edits tool bar.<\/p>\n

\"step5b\"<\/a><\/p>\n

Notice the Logic now appears to be normal:<\/p>\n
