Industrial Legacy Systems

Legacy Systems: Maintenance

Maintaining and upgrading legacy systems is one of the most difficult challenges industrial and manufacturing managers face today. Constant technological change often weakens the business value of legacy systems, which have been developed over the years through huge investments. Managers struggle with the problem of modernizing these systems while keeping their functionality intact. Despite their obsolescence, legacy systems continue to provide a competitive advantage through supporting unique industrial processes. Routine checks allow for preventative maintenance, and for replacement parts to be ordered before they are desperately needed. Here at MRO Electric and Supply, we stock a large number of classic and legacy products which can be shipped in record time.

Legacy Systems: IoT

When new technologies arise, engineers simply cannot uproot existing systems. However, some legacy controls can be connected to the Internet of Things. This allows for a high level of data acquisition which can be stored, processed, and analyzed. Several IoT products can also support remote monitoring and control. Many Modicon Quantum Series products have an Ethernet port that allows for this upgraded connectivity. However, not every legacy system has these capabilities.

Legacy Systems: Security

Targeted attacks on industrial systems always remain a threat as our society plows forward into the computer-driven Information Age. Securing legacy systems that were designed to communicate point to point is a enormous challenge. Many of these older systems were installed pre-internet era, are not designed for connectivity, and have no means of authenticated commands that are received. System interruptions for security updates can be difficult and costly, and downtime is expensive. It is always a challenge to find ways to increase security for legacy systems. One important tip is to always keep the software for connected legacy systems updated with the most current version.

Legacy Systems: Looking Forward

Although replacement supplies and remanufactured parts can be ordered for many years to come, it is important to keep in mind that no legacy system will last forever. In this current sluggish world economy, often the best answer is a well-planned, slow and steady upgrade.

A06B-6058-H005: Beyond the User Manual

Generally, Fanuc AC servo motors, like the A06B-6058-H005, have no parts that wear off or that must be replaced periodically, unlike DC servo motors, which have brushes that must be replaced. However, you should perform period maintenance for servo motors so as to keep their initial performance as long as possible and to prevent breakdowns. AC servo motors have precision sensors — their incorrect use or damage caused during transportation or assembling can result in breakdowns or accidents.

It is recommended that you inspect servo motors periodically, and of course we offer a 12 month warranty on all Fanuc products purchased from MRO Electric.

Receiving and Keeping the A06B-6058-H005

When you receive a A06B-6058-H005 module from MRO Electric, make sure that the motor is exactly the one you ordered, in terms of model, shaft, and sensor specifications, and make sure that no damage has been caused on the motor. Servo motors should be kept indoors as a rule. The storage temperature range is -20 to +60 Celsius. Do not place or install AC servo motors in a place where it is extremely humid and dew is prone to form, where there are steep changes in temperature, where there is constant vibration, or there is lots of dust and trash. Constant vibration may cause damage to the shaft bearings.

Daily Inspection Procedures

Before starting operation, or periodically (once a week or month), you should inspect the AC servo motors for vibration and noise, outside damage, stains and smudges, overheating.

Check the motor for abnormal vibration by hand, and noise by ear when the motor is not rotating, rotating at low speed, and accelerating and decelerating.

Check the Pulsecoding cover (read plastic) for crevices and the motor surface (black coating) for scratches and cracks. If you find a crevice on the Pulsecoder cover, you should replace it. If there is a scratch or a crack on the motor surface, the user should repair it by himself as required. If coating has come off, dry the portion of interest or the entire surface and coat it with paint for machines such as urethane paint.

Check the motor surface and bolt holes for oil or cutting fluid. Wipe off oil and cutting fluid on the surface periodically. Oil or cutting fluid can damage the coating by chemical reaction, possibly leading to failure. Also check how such liquid leaks onto the motor, and repair if needed.

Check to see if the motor is too hot during normal operation. Attach a thermolabel on the motor surface and check it visually to see if the motor becomes too hot during normal operation.

Joe Kaminski Leave a comment

Our previous blog post on the 140CPU43412A describes the 140CPU43412A Configuration and Setup. 

140CPU43412A Hot Standby

You cannot create a Quantum Hot Standby configuration running one 140CPU53414A PLC with Unity firmware and one with NxT firmware. When using an NxT configuration in hot standby, both PLCs must have NxT firmware. When using a Unity Quantum hot standby configuration, only specific hot standby controllers can be used. The 140CPU43412A and 140CPU53414A PLCs are not supported in Unity Hot Standby configurations.

140CPU43412A Error Codes

The following are the error codes for the 140CPU43412A:

140CPU43412A Firmware Part II

Joe Kaminski 1 Comment

Phase 1 of firmware restoration is described in our previous blog post on the 140CPU43412A firmware.

140CPU43412A Firmware Part II

Restoring a 140CPU43412U (Unity) to 140CPU43412A (Concept):

Phase 2

During the download:

• Do not power OFF the PLC

• Do not power OFF the PC

• Do not disconnect the cable

• Do not shut down OS loader

Any loss of communication during the update procedure can cause severe damage to the CPU or NOE module. Failure to follow these instructions can result in injury or equipment damage.

Reset the PLC

Once the download of the intermediate binary file has completed, the PLC has to be initialized. This task can be performed by one of the two following actions:  Reset the PLC by pushing on the Restart button located on the CPU (for more information, refer to the PLC technical documentation).  Power OFF then ON the PLC. Once the PLC has restarted, go to Phase 3: download the final Concept OS.

Phase 3

Presentation

The final binary file “q5rv135E.bin ” (140CPU34312 in our example) has to be downloaded. For that, follow the same procedure as the one described in the Phase 1.

Checking Version (optional)

If needed, you can check the new CPU version. For that  Open the OS loader tool.  Select the communication protocol.  Click on “Connect.” Then Click on “Properties.”

140CPU43412A Firmware Part I

Joe Kaminski Leave a comment

Click now to view our blog on the 140CPU43412A Configuration and Setup. 

140CPU43412A Firmware

The q5rv144e.bin file supports both Concept (IEC & 984) and ProWORX PLCs.

In order to restore a 140CPU43412U (Unity) to a 140CPU43412A (Concept), three main phases are required.

Phase 1 – Restore the PLC to Concept with an intermediate OS. 

Phase 2 – Power OFF then ON the PLC. 

Phase 3 – Restore the Operating System with the appropriate file.

These phases are mandatory and cannot be by-passed.

Phase 1: 

Launching the OS Loader

The OS loader (provided with Unity) allows the user to download the Operating System to the PLC. To open it click on Start/Program/SchneiderElectric/Unity-PRO/OS loader.

Select the Communication Protocol

From the main screen of the OS loader, click on the “Next” button. To download the Operating System into the PLC, select the right communication protocol (in accordance with established physical link) and click on the “Next” button.

Select the Target Device

On the Device Type field, select Processor and the other needed parameters (Modbus address….). Then connect to the selected PLC (Node).

Select the Download Function 

From the screen described above press the “Next” button. A new screen is proposed: select “Download OS to device”.

Select the File to be Downloaded

Click on the “Browse…” button in order to select the file to download into the PLC. In this example we will restore the OS from 140CPU43412U to 140CPU43412A firmware. For that select the following folders: Quantum\Processor_modules\Unity_to_Concept. To restore the OS from Unity to Concept, two binary files can be selected:  Unity_to_Concept_43412A.bin (allows to “format” the processor to Concept)  q5rv135E.bin is the OS that will finally be downloaded in the processor. In our example we have to “format” the processor (remember, we still are in the Phase 1) then select and Validate “Unity_to_Concept_43412A.bin”. Once done click on the “Next” button.

Download the Intermediate OS

Once the previous screen is validated a warning is displayed: Click the “Okay” button. Two screens that give information regarding the file, the processor and the download are now displayed. Note: If the system detects a discrepancy on the hardware or on the OS version, the download will not be possible. This is indicated by a red cross and the “Next” button becomes unavailable. Solve this issue and continue. When the hardware – OS are compatible, click on the “Download” button to launch the download of the intermediate OS file.

Click Now for 140CPU43412A Firmware  Restoration Phases 2 & 3.

UD75 Configuration and Setup

Joe Kaminski Leave a comment

You can check out our previous blog post  on the UD75 here for more information. Check out the UD75 product page on our website along with all of our other Unidrive options.

UD75 Configuration
  1. Isolate the drive from the mains supply and allow 5 minutes for the DC Bus capacitors to discharge.
  2. Insert Large Option Module as shown below. Ensure that it is correctly inserted. The module will click firmly into place.
  3. To remove the module, pull on the black tab, and the module will disengage from the connector and pull out of the drive.
UD75 Configuration: Cable Screen
The screen of the cable at every node on the network MUST be connected to the screen terminal (pin 3) on the CTNet terminal block. When the screen is stripped back to connect the twisted pair to the CTNet terminals, keep the exposed section of the cable as short as possible. On the CTNet PC Interface Adapter Card, there is no screen terminal. The screen should be cut and taped back to prevent it coming into contact with any other surfaces. The on-board terminal resistor should not be connected.
UD75 Configuration: Network Termination
The network MUST be fitted with terminating resistors AT BOTH ENDS!!! If resistors are not fitted, the network appear to work OK, but the noise immunity of the network will be drastically reduced. The terminating resistor value should match the nominal characteristic impedance value for the cable; in the case of the customized CTNet cable, the terminating resistors used should be nominally 78Ω. PC ISA and PCMCIA cards for interfacing a PC to CTNet are available from CT SSPD.

For price and ordering info you can email sales@mroelectric.com or call 1-800-691-8511. We have these and all the other Control Techniques Unidrive Classic option modules in stock, along with the drives themselves.
