MR Control ltd

Allen Bradley Page

MR Control has developed a reputation for leading edge software design & programming.

We take advantage of the very latest Rockwell Automation hardware & software technology and make it work to the benefit of our customers. We have many years of experience in working with Rockwell PLCs in a wide variety of machine & process control applications. We support all Allen Bradley PLCs from the PLC2, PLC3, PLC5 and SLC500 ranges right through to today's powerful ControLogix PLC solutions.

We offer a complimentary range of FactoryTalk View SCADA solutions and machine based PanelView Plus HMIs. We take advantage of all that Rockwell has to offer particularly with the FactoryTalk Metrics suite of applications. We get hold of your plant floor production data and make it visible with automatic collection & reporting of data. FactoryTalk Metrics (similar to RSBizWare PlantMetrics) produces clearly defined reports allowing you to identify problem machines or equipment. Using FactoryTalk Transaction Manager (previously RSSQL) we can manage and store all your shop floor data and link to higher level manufacturing systems. We also integrate FactoryTalk Batch and FactoryTalk Historian to provide a complete range of manufacturing solutions. MR Control-installed FactoryTalk systems are saving our customers costly downtime and boosting their profits.

SLC 5/04 PLC controlling a Laminating Machine using remote DeviceNet I/O

Which Rockwell Allen Bradley PLCs can you program?
All of them (see below)

MicroLogix

Small I/O shoebox systems - cheap and simple to use (requires the Rockwell RSLogix 500 software)

 

ControlLogix series

Current range of large PLCs - very useful for certain machine motion systems (which are very simple to configure), 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 logix, which will certainly prove popular with professional programmers, but may not find favour with occasional users. The programming software has some clearly unfinished areas such as cross referencing and print previews. The ladder is very reliable, but unfortunately the structured flowchart is not quite as robust.

FlexLogix series
Latest model for mid-range control applications
CompactLogix series
Low-end control systems - this is our recommendation for replacement of SLC and MicroLogix series systems, now some models available with Ethernet ports built in (at last, a PLC manufacturer who realises the future of PLC programming interfaces!)

PLC 5 series

Top End, very powerful PLCs, this range was the flagship of the Allen Bradley/Rockwell range before ControlLogix appeared.
SLC 500 series
Middle range PLCs typically with RS232 or DH1/DH485 ports
SLC 5/03
Middle range PLC with DH485 communication port, but oddly no DH+ port
SLC 5/04
Shoebox type PLC with Data Highway+ communication port, but oddly no DH485 port
SLC 5/05
Shoebox type PLC with Ethernet port but oddly, no Data Highway+ communication port. One day all PLCs will have an ethernet port (being the best programming port there is by a long way), but in the meantime, they're VERY expensive
PLC 2 series
Very old PLC, requires old or new programming software: TA, T3, T50 or PCMK card with PLC2 lead

PLC 3/10 Series and

PLC 3 series

Old PLCs, we do specialise in replacing these with PLC5s (you can just replace the CPU with a PLC 5 CPU then rewrite the software of course...)

Rockwell Allen Bradley Graphics Systems

Panelview Configuration Softwareonfiguration
Which Allen Bradley Graphics Systems can you program? All of them

PanelViews

Reliable, functional units with reasonable programming software. The range is now superseded

PanelView Plus

Reliable and easy to use (the latest configuration software is a big improvement), functional units with fair programming software. The range has now superseded the Panelview systems. it is much more flexible and powerful.

RS ViewStudio ME

Latest HMI System - very pretty but comms are nasty to set up

RS ViewStudio SE

Latest SCADA System - has many new features over RSView32 but some important ones are still lacking

RS View32

Powerful top end SCADA system - still features in many of our projects

Rockwell Allen Bradley Programming Software

T The old "AB 6200" Ladder

Which Allen Bradley programming software do you use?
All of them
6200 PLC 5 software (DOS)
Reliable, ponderous but OK (beeps a lot!)
APS SLC 500 software (DOS)
Fairly reliable software. Annoyingly not quite the same as the above 6200 software.

Rockwell RSLogix SLC 500 (windows)

Windows Version of the AB Programming software for programming the SLC Range of PLCs

There are two versions - one which is acceptable for low end SLCs (5/03 and below), the other which allows you to do "advanced" things such as on-line editing on the top end SLCs

Rockwell RS Logix PLC 5 (windows)

Windows Version of the AB Programming software for the PLC 5 range.
Rockwell RS Networx dor DeviceNet

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 RS Networx dor ControlNet Like the above version but for setting up ControlNet systems
FactoryTalk View Required to program View SCADA or the panelview plus range of operator panels
Rockwell Panelbuilder 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 .
What do you recommend?

We use all versions. Complex communications is much easier in the Windows version, and this is the way of the future.

Allen Bradley Programming Hardware

Which Allen Bradley Hardware Programmers do you use?
Most of them:
T3
Very old Custom Programmer - programs the PLC3 and PLC 2 family
T50 (DH+)
Old Custom Programmer - it's a PC with specialist cards installed, extremely expensive.
KT/KTX Card in PC (DH+)
The cheapest and best method (unless you have a portable with no slots when you have to use the PCMK card)
1747-PIC (DH485)
The cheapest and best method of programming the DH485 on low range SLC CPUs (up to SLC 5/03). Note that many SLCs can be programmed with a simple null modem serial cable.
RS232
You can use a simple RS232 lead (null modem) to program some SLCs and PLC 5s. This does depend on the configuration loaded (the configuration can disable the RS232 port) so beware!

PCMK Card (DH+, 485)

Very useful, but not so easy to use now most PCs don't come with PCMCIA socket

Ethernet

By far the best solution - and one day, all PLCs will come with Ethernet ports....
