    The screen shot shows the L18 is configured for 10 slots.  But there are only three devices. Fix the chassis configuration.

    The 10 slots showing in the RSLinx screen shot is normal and shows the total number of slots available (0-Controller, 1-Embedded I/O, 2 thru 9-Expansion I/O). There is only one expansion module (IB8), as shown. The 1734-VTM and 1734-CTM are Voltage Terminal and Common Terminal Modules that add extra points for wiring field devices. They don't count as I/O modules.


  2. As Joe E. stated, RSLogix5000 ended at v20 and was renamed to Studio 5000 at v21. However, all revisions use the same .acd file extension. All your PLC programs will show up on the start page, but you have to have the correct version of software to open it.

    In addition to the software name change at v20 - v21, major hardware changes occurred. In your case, the CompactLogix L32E was capped at v20. The CompactLogix 5370 series was released for v21 and forward. So, you will need v20 or earlier to use with the L32E. It uses the same license. You just need the software. If it's not available on your current media and you don't have a TechConnect contract, try your A-B supplier.

  3. If you have a TechConnect account, look at article 26787. If not, go to RSLinx Classic help and search for "Configure Browse". Include the quotes to limit results. Basically, you have to manually add devices you want to see on the remote network. Older versions of RSLinx did not store these configurations, so you had to reenter them if they were lost. I think the newer versions store the configurations when you do a backup.

  4. The PanelView C600 has a built-in web service that can be used to design your application using a PC and web browser. The DesignStation software mentioned by AndrewG is used to develop an application offline (if you don't have the terminal available). According to RA's Product Compatibility & Download Center, DesignStation is for v1.070 and older firmware. It has been superseded by Connected Components Workbench (CCW) software. Below is a link to the PanelView Component user manual.

  5. It's been a few years since I had a similar problem, so I may be off-base. Do the drives that aren't connecting have a Remote (door-mounted) keypad? That usually connects to Port 1.

    I think the problem may be that the drive configuration stored in the PLC does not match the drive. If the drive is set up differently than default, e.g., remote keypad, using Datalinks, etc., then RSLogix5k creates a unique, module-defined data type.  I think the easiest solution is to do the following.

    1. Go online with PLC, upload and save the program.

    2. Go offline.

    3. Open the drive's Module Properties  window.

    4. On the General tab, click the Change button under Module Definition.

    5. In the bottom, left corner, click the Match Drive button and browse to the correct drive.

    6. Click OK and select Upload Entire Device.

    7. Accept the changes and close the Drive's Module Properties  window.

    8. Repeat for all drives in question.

    8. Save offline project and download to PLC.

  6. There are examples in the on-line help. If you bring up the "Command Wizard Step 1 of 2" window and double click on "=", it opens a "Command Wizard Step 2 of 2" window. Click on the Help button at the bottom. It explains the syntax and has an Examples link near the top.

    In your case, the syntax would be PLC_Tag1 = HMI_Tag1 * 0.75 if you have multiple commands that you want to execute in order (synchronously) or & PLC_Tag1 = HMI_Tag1 * 0.75 if you don't care what order they execute in (asynchronously).


  7. From A-B reference manual page 41:

    Auxiliary Power Supply The optional Auxiliary Power Supply module, 20-750-APS, is designed to provide power to a single drive’s control circuitry in the event incoming supply power to the drive is removed or lost. When connected to a user supplied 24V DC power source, the communication network functions remain operational and on-line. A DeviceNet program can also continue to run and control any associated input and outputs. The auxiliary power supply module is designed to power all peripherals, I/O, and connected feedback devices.

    The installation instructions also mention the 20-750-APS on page 266.

     


  8. Yes, the 1734-EP24DC can handle the three additional modules. Yes there is a limit. You can find the limits in the Bulletin 1734 Selection Guide. You can also download and install Rockwell Automation's Integrated Architecture Builder, which will allow you to configure your rack. It automatically does the calculations and inserts additional power supplies as needed.

    Some of rdrast's comments are not accurate. The POINT I/O series has two buses to be concerned with - POINTBus and Field Power Bus. The POINTBus supplies operating power to the modules. The current requirements for the modules vary from 75mA to 220mA or more. The 1734-AENT adapter can supply up to 1000mA for the POINTbus. The EP24DC and EPAC can expand the POINTBus an additional 1300mA (1000mA if mounted vertically) for modules to the right. The EP24DC is for 24VDC supplies and the EPAC is for 120/240VAC supplies. The EP24DC and EPAC can also be used to break the Field Power Bus if you want to segment or partition your system (inputs, outputs, digital, analog, etc.). Note: If you are using 120/240VAC modules, you must have an EPAC expansion power supply in the system. 120/240VAC cannot be connected to the AENT.

    The Field Power Bus supplies power to the field devices. The AENT can provide 9A (1A goes to adapter itself) of current for field devices to its right. The EP24DC and EPAC can provide 10A of current for field devices to their right.

    The 1734-FPD is only used to break the Field Power Bus. It does not expand the POINTBus. It can be used for 5-125VDC or 24-240VAC field applications. The FPD can provide 10A of current for field devices to its right.


  9. I don't have an L36ERM processor, but based on other CompactLogix 5730-L3 controllers I've used and A-B's literature, the two Ethernet ports use embedded switch technology. That feature allows for different network topologies: Device Level Ring, Linear, or Star. The ports are not independent and the controller has only one IP address. I agree with the third paragraph of kaiser_will's post about using a device supporting NAT - either a managed switch with NAT, 9300-ENA,1783-NATR, or similar device.

  10. My opinion from past experience: The basic SLC 500 series is over 20 years old. There's a huge installed base, so A-B is not going to drop it, yet, but they do want to discourage people from using it in a new application. What's the best way to do that? Inflate the price. It sounds like you already have RSLogix 500, so unless there is some compelling reason for using an SLC (installed base at your plant, spare parts inventory, etc.), I believe I would opt for a MicroLogix 1400, as suggested earlier in this thread.

  11. On the desired display, add three numeric display objects, separated by ":" text objects. The numeric displays are for HH:MM:SS. Configure them as follows. HH: Field length = 2, Decimal places = 0, Format = Decimal, Expression = unit1timer / 3600 MM: Field length = 2, Decimal places = 0, Format = Decimal, Leading character = Zeroes, Expression = (unit1timer % 3600) / 60 SS: Field length = 2, Decimal places = 0, Format = Decimal, Leading character = Zeroes, Expression = unit1timer % 60 Make sure unit1timer is a Long Integer data type.
