Allen-Bradley SL500™

Written by Kang Abu on 6:21 PM

Understanding the basic features of the SLC500™ (Small Logic Controller) in your facility will maximize your productivity. The SLC500 includes fault detection with built-in diagnostics. Understanding these features is critical to running an efficient operation.

Battery

A lithium battery retains the SLC500 memory. The battery is located in the Central Processing Unit (CPU) next to the power supply of the SLC500 rack. Replace the battery on an annual basis or if the low battery signal activates. The Besser part number for the battery is 113773F00BA.

Fuses

A fuse protects the SLC500 power supply and, if burned out, will cause the indicator light to turn off. The fuse will open due to an incoming power problem or a short condition within the power supply. Insure the replacement fuse is equivalent to the one being replaced. The fuse is a 3 amp time-delay – Besser part number 111847.

Memory Loss

A power surge or a low battery may result in memory loss. The CPU fault light will illuminate to indicate a problem. To restore the memory, turn the panel power OFF. Insert the Electrically Erasable Programmable Read Only Memory (EEPROM) into the socket of the CPU and restore the power. The SLC500 will automatically read the EEPROM into Random Access Memory (RAM) and go into RUN mode. The CPU RUN light will illuminate to indicate a successful transfer. Turn the power OFF and remove the EEPROM from the unit. Note: In the case of Besser Lithibar equipment, the EEPROM remains in the unit. If a memory loss occurs, power cycle the SLC500 and the unit will return to run mode.

Preventive Maintenance for Electrical Panels and Graphic Display Units

Written by Kang Abu on 6:18 PM

"Cleanliness is the Best Policy" when it comes to maintaining electrical equipment in a concrete products facility. Focusing on a few simple practices will extend the life of electrical panels and graphic display units that are connected to your equipment.

Best Practices:

  1. Keep panel doors and box covers closed. Dust and moisture are two of the biggest enemies of electrical devices.

  2. Remove debris from electrical components. Heat build-up can occur when electrical devices are covered with dust or concrete. Dirt, once inside a component, is trouble.

  3. On a monthly basis, check electrical connections and keep them tight. A loose wire either in a panel or on the machine will cause electrical arcing. Arcing can cause intermittent machine operation and eventually a breakdown.

  4. Keep electrical wiring diagrams, logic documents and operating manuals clean, neat and easily accessible. Plant personnel will need these items to effectively troubleshoot the equipment.

  5. Ensure tags and labels are readable and securely attached to electrical devices. This will help identify items when servicing the equipment.

Overall plant efficiency and productivity is increased with preventive maintenance. The added effort will pay for itself in the long run. Maintaining a clean facility also improves the overall atmosphere. Employees will show more pride when their workplace is neat and organized. Attitudes are more upbeat which positively affects work quality. An uncluttered environment also promotes safety.

DF1 to DH+ Passthru using WinLinx or RSLinx

Written by Kang Abu on 6:16 PM

For OLD Application...

SLC 5/04 processors (OS401 and greater) support DF1 to DH+ Passthru. With this feature, you can connect to a 5/04 processor through Channel 0 using the DF1 protocol and access any node on the DH+ network, regardless of the baud rate of the DH+ network. It is also possible to connect a modem to Channel 0 and connect to any node on the DH+ network via modems.

At this time only PanelView devices at FRN 3.3 or higher can be accessed using the SLC 5/04 passthru. Pre FRN 3.3 PanelViews do not recognize PCCC messaging which is the protocol used on the DH+ side of the SLC. An alternate bridge solution would be a 1770-KF2. The customer should consult their local distributor for other hardware, serial to DH+ bridge, solutions or firmware upgrades.

To use this functionality with the RSLogix 500 software, you need to use the following procedure:


PROCESSOR SETTINGS:

RSLogix500

1) Configure Channel 0 of the 5/04 processor for System Mode using Full-Duplex. This can be done by accessing the Channel Configuration Window and choosing the appropriate settings.

**Note the Passthru Link ID setting for Channel 1 (which is 2) and Channel 0 (which is 1). If channel's 1 and 0 have the same link ID's then RSLinx/RSWho will not see through to the DH+ network.








2) You must then access the Chan 0 Tab on the Processor Status File and disable the DH485 to DH+ Passthru and enable DF1 to DH+ Passthru by setting both S:34/0 AND S:34/5 high. Note: If you want to view active DH+ nodes in the 5/04 status table, S:34/1 must also be set.






The above settings must then be downloaded to the processor using either Winlinx or RSLinx. Once the program has been downloaded, comms drivers must be altered as detailed below to see the entire DH+ network. Also note that the driver verification in Winlinx and Auto-Configure in RSLinx will no longer function correctly since DF1 packets are being passed through Chan 1. Both functions will still determine the baud rate, but acknowledgements will no longer be received causing the error checking to fail.

COMMUNICATION SETTINGS:

WinLinx

The uLogic/KF3/CH0 driver was initially used to download the project to the 5/04. This driver must be deleted from Winlinx and the KF2/KE driver must be used instead. Be sure to set the correct baud rate and turn on the Don't Verify Settings radio button. Click OK to accept the driver changes. The SuperWho screen will poll address 1-77 and display any active DH+ nodes.






RSLinx v1.7

To download the program, recall that the Device Type option was initially set to SLC-CH0. Change this to KF2/KE and click on OK.







Select Communications > SuperWho and 'right-click' anywhere inside the Who screen and choose Configure SuperWho. In the dialog box, change the Station Update Mode from Graphical (default) to Normal and click OK. The resulting Who screen will begin polling from node 1 thru 77 octal and display all devices connected to the DH+ network.







Remember, the RSLogix500 Who configuration is separate from the RSLinx Who configuration. Be sure that the Normal mode is chosen in both configurations.

Note: RSLinx 1.7 requires that one of the nodes on the DH+ network be set to station 1. If none of the nodes are set to 1 nothing will appear in the SuperWho. This is not a requirement for RSLinx revision 2.1.


RSLinx v2.0

Once the program has been downloaded, in the driver configuration dialog, change the Device Type to 1770-KF2/1785-KE and click OK. Click Close to save the change. If Autobrowsing is enabled, the RSWho will automatically poll the DH+ network using your AB_DF1 driver.





Note: RSLinx 2.0 requires that one of the nodes on the DH+ network be set to station 1. If none of the nodes are set to 1 nothing will appear in the RSWho. This is not a requirement for RSLinx revision 2.1 (or higher).

Butterfly Valve Installation

Written by Kang Abu on 6:13 PM

Learn In Detail...

Proper Installation Techniques must be followed to prevent immediate or premature failure of Butterfly valve seat, disc or shaft on any size or make wafer-style Butterfly valves.

PROPER INSTALLATION PROCEDURE IMPROPER TECHNIQUES
Pipework opened to allow free valve entry with the disc in a semi-closed position.

Pipework not spread sufficiently - could tear rubber seat. Disc in open position will hit flange and score disc edge.

Valve in semi-closed position to (1) protect disc edge, (2) reduce rubber interference during installation and start-up, and (3) help reduce initial torque build-up.

Disc as shown in fully closed position causes seat distortion. When flanges are drawn up, rubber will close around disc edge creating excessive torque in initial operation.

Disc should be turned to full open position after flange alignment and before evenly pulling up flange bolts.

Incorrect pipe alignment will cause interference between disc edge and flange face creating leakage and excessive torque for opening valve.

Software PLC - SIMATIC WinAC RTX 2008

Written by Kang Abu on 5:12 PM


WinAC RTX 2008 is used when high performance, high data volumes and at the same time hard real time are required for the automation task. The optimized runtime system supports the processing of extensive and demanding PC applications in parallel with the control task. The performance of WinAC RTX 2008 can be scaled across the PC platform.


Applications range from machine-level control tasks with rugged embedded PCs to high-end applications on PCs with enhanced performance (e.g. SIMATIC Rack PCs).


Platforms

SIMATIC WinAC RTX 2008 runs on standard PCs wit Windows XP Professional.yet excellently fits to SIMATIC Industrial PCs.In particular, the use on embedded PC platforms such as the SIMATIC Microbox PC 427B or Panel PC 477B with Windows XP Embedded results in cost-effective and very rugged solutions.The Microbox PC 427B is characterized by its diskless and fanless operation. WinAC RTX 2008 uses the main memory of the PCs and offers program backup on the hard disk. Non-cyclic data such as production parameters or recipe data can be stored permanently on the PC's hard disk with the help of system functions (SFC 82 – 84). In addition, all data can be held retentively in conjunction with an uninterruptible power supply (UPS).


I/O connection

Employing WinAC RTX 2008 it is possible to connect the I/O via PROFINET. This requires either the integrated Ethernet interface of the SIMATIC PC or a CP 1616 (PCI) or CP 1604 (PCI-104) communications processor.Open User Communication permits open communication of WinAC RTX 2008 via TCP and UDP. Open data exchange with any communication partner via the PROFINET interface is possible. WinAC RTX 2008 makes use of the TSEND/TRECV blocks for this purpose; they are available as library for all SIMATIC S7 CPUs. In addition I/O can be connected via PROFIBUS DP at up to 12 Mbit/s via the integral DP interface of the SIMATIC PCs or via communications processors (CP 5611 A2/5613 A2). Up to four PROFIBUS lines can be operated with up to 500 slaves.


Isochronous mode

In addition, with its PROFIBUS interfaces WinAC RTX 2008 also supports the system function isochronous mode. With isochronous mode, high-speed, time-dependent applications such as closed-loop controls can also be implemented with distributed I/O. This means that in addition to the control job other functions can be integrated into a PC or smaller, more economical PCs can be used for the same job.


Retentivity

On exiting, WinAC RTX 2008 saves all the data declared as retentive to the hard disk. In order to ensure a defined shutdown of the Software PLC in the event of an unexpected failure of the PC voltage supply, an uninterruptible power supply (UPS, e.g. SITOP DC UPS) can be used. SIMATIC PCs with integrated, non-volatile memory enable up to 128 KB of retentive data to be stored in the event of voltage dip, regardless of the file system. For SIMATIC PCs without integrated, non-volatile memory, the WinAC NV128 plug-in card is available. This enables up to 128 KB of retentive data to be stored. Depending on the version of the PC, however, the use of a UPS may be necessary.
