Which Rockwell
Control Logix PLCs can you program?
|
All of them! |
|
Logix 5000 programming |
Rockwell's current range of large PLCs - very useful when fast processing is required and powerful when used with machine motion systems (which are very simple to configure). They are possibly expensive otherwise compared to the SLC range. The Logix 5550 and now the Logix 5555 have large amounts of memory (at last!) and use a TAG based ladder programming language, which will certainly prove popular with professional programmers, but may not find favour with occassional users....however when used correctly this will greatly aid fault finding and other maintenance. |
| Which CPUs are available? |
Control Logix
These CPUs are compatible with each other and form the high powered end - the Control Logix CPU family:
Other processors are also available and form other families (which can also be programmed with the RS5000 software) The CompactLogix (low-end) range:
The FlexLogix (middle) range:
and other ranges:

Which Rockwell or Allen Bradley
programming software do you use?
|
There are many old versions (which, in on-line terms, are not really compatible with each other), you really have to upgrade to the latest one....which is currently version 11 of RSLogix5000. |

Rockwell RSLogix 5000 |
Windows based software - unlike pretty much all other PLC software this uses tagnames only to program with - you no longer use N7:20 or B3/41 but you use sensible (hopefully) names such as "EStopHealthyBit" or "Pump1HoursRun". This will make the ladder logic clearer to understand. Maybe. Requires a mouse (which is of course a problem for industrial sites!) There are various current versions of the Logix5000 Programming Software available depending on what family of processors you require for your project. The three versions are for programming these families use the following CPUs:
We must assume Rockwell's intention is that one day the microLogix and SLC family will be phased out and everyone will use Logix5000. |
| Rockwell RSNetworx for DeviceNet software |
Used to program the DeviceNet I/O bus. Always ensure you have the *very* latest version of the module EDS files (and don't forget the 121 ohm resistors!)
|
| Rockwell RSNetworx for ControlNet software |
Like the DeviceNet software, this is required to program the ControlNet links used to:
|
| Rockwell Panelbuilder32 and Panelbuilder16 | Required to program the panelview range of operator panels |
| Rockwell RS Linx | Required to link PCs to PLCs for Rockwell software. Various versions are available, lite for PLC programming, higher versions for linking (for example) Intouch and Excel . |
Tags Example
Here an example of a the tags from a very small program is shown. This layout has many advantages and some disadvantages. You can see all the tags and their values quite easily. You can see dependent tags (ie a high Speed Counter Tag would have "Current value", "Preset", "high alarm" (etc). dependent tags which are all connected to the main tag). You can easily find any dependent tags, which will save hours of poring over manuals trying to find (for example) which N10:xx tag is the high speed counter preset limit. In theory at least, errors through mistyping a number (ie typing N7:1 instead of N7:2) will be greatly reduced.
Some Disadvantages
Motion Control Example
Here an snippet of an example of a motion control system. Many specific motion control commands are built into the programming language such as:
These inbuilt instructions allow complex motion control systems to be created quickly and reliably.
