In order to help a client of mine I would like to retrieve a program from an old Eberle PLS 514 and from one Eberle BC52 Control Panel. Anybody help me?

Hello man, Without putting much thinking on this, my suggestion is: Since you know the distance you're going to move, the acceleration rate and the initial speed, then you know the final speed: V1 := SQRT(V0**2 + 2*a*(d1-d0)); Where: "V1" is the final speed "V0" is your initial speed "a" is the acceleration "d1" is your final position "d0" is your starting position Once you have this, one way to reference your VFD could be: Start a timer, and: VREF := V0 + a*TIMER_01.ACC; Where: "VREF" is your reference to the VFD "TIMMER_01" is a timer Once VREF equals V1 you're done Surely you will want to limit your reference to a maximum and reset the timer when done Hope this helps

Generally you calculate the radius dividing the line speed by the angular speed being careful to avoid calculations when speed is very close to zero

Exactly, this OR is a bitwise operator that takes two double integers and compare them bit by bit resulting in another DINT having a "1" in every position where either original operand has a "1" Some times this things become a true headache Bye

The information you need is in the manual: 2098-rm003_-en-p.pdf

There isn't, but you can create your personal Add-On Instruction (AOI) that does exactly what you want. Remember b_carlton's: "The accumulated value always counts up. Calculate (Preset - Accumulated Value). In some cases the Accumulated value goes past the preset so take whatever steps are needed for a zero time remaining display." Bye

Channel 0 is bit 161 (10/1) Channel 1 is bit 165 (10/5) Channel 2 is bit 169 (10/9) Channel 3 is bit 173 (10/13) Channel 4 is bit 177 (11/1) Channel 5 is bit 181 (11/5) Channel 6 is bit 185 (11/9) Channel 7 is bit 189 (11/13) See: 1769-in067_-en-p.pdf

Make your index_element ("i_CellPart_Working" in this case) accessible to your Station_45 Program. In other words, your index_element is not in the scope of the program where you are trying to use it. Your syntax is ok Bye

Please, post your program and I'll help you

I remember myself unluckily trying to do Spanish special characters (ñáéíóúü). Apparently Panelbuilder software (not Panelbuilder 32) has the feature you want, see: 2711-um020_-en-p.pdf

Hi BCS, Just want to point out that in the case you chose the CompactLogix option, take into account that the 1769-L23E-QBFC1B has LOW-RESOLUTION analog I/O's, relies on a battery to store the program and has very limited expansion capability. The 1769-L24ER-QBFC1B is much better. it's like an improved version of the one you selected. Opto22 is cheaper and reliable (modules are guaranteed for life) and the software is free. I have used opto in two temperature supervision and registration projects of about 40-zone each with up to three racks networked together. BUT, on the other hand, opto has a very unique way of thinking and programming that I have never felt very comfortable with, programs are hard to troubleshot and for some reason it takes me twice as much time to program an opto than it takes me to program an AB. Hope this help

If a small controller is an option for you instead of a micro and you feel comfortable with Logix5000 I particularly love the 5370 L2 line (like 1769-L24ER-QB1B, 1769-L24ER-QBFC1B or 1769-L27ERM-QBFC1B) so you go with newer technology instead of "stepping back" to MLX1500

Micrologix 1500 uses compact I/O modules and the 1769-IM12 is a 240Vac input module

Hello Do the cylinders have sensors to detect whether the plunger is completely extended or completely retracted? If so, use them (the sensors)

Hi, In a physical selector switch you unavoidably must pass through all intermediate positions when moving from one position to another. I personally like to use an Inc/Dec Numeric Entry Object for this purpose. I am attaching two files showing how. In this example you have an integer limited to three possible values (1, 2 & 3) and use the up and down arrows to move from one value to another. Bye SelectorSwitch.PBA SelectorSwitch.RSS

Saludos paisano, This is what you have Node 1: SLC - retorno moldes pan 8 (HORNO2.RSS) Node 2: Panel View - (HORNO_PA HORNO CON PARO.PVA) Node 3: Panel View - (HORNO_PA RETORNO.PVA) Node 4: SLC - retorno de moldes bolleria (RETORNO13122012V6.RSS) Try this: Back up the Panel View application you want to retain Edit the application with PanelBuilder32. In the directory tree double-click on Application Settings - Communication Setup. Now you should have two open windows. On the DHPlus window delete the node you want to disincorporate Close the windows, validate the application and then delete all references to the node you just deleted until your application finally becomes valid. (this will probably be a tedious work) Save your application and download it to the Panel View that will remain I recommend you to wait for other ideas just in case there is any simpler way to accomplish what you want. Good luck!

dmargineau, Rockford, thank you both. I am keeping the older one too, just in case I can't get the newer one to work well. Thanks again.

Dear colleagues, I am planning to change my laptop for a newer one which has a 64-bit cpu. Does anybody know if there is any incompatibility issue between any Rockwell software and 64-bit cpu's? I am especially concerned about RSLinx drivers and the PanelView USB RNDIS Device driver The software's I most frequently work with are: RSLogix 5000 (v13 to v20) RSLogix Emulate 5000 Factory Talk View Studio RSLinx Classic RSLogix 500 RsLogix Emulate 500 PanelBuilder 32 DriveExecutive Ultraware RSNetWorx for DNet I also have installed some others that I utilize less frequently. I would appreciate your help, thank you.

One of my clients is an integrator who standardized his plc's output modules to transistor and always uses external slim line relays (700-HK...) to drive the loads. This seems a good idea to me because you do not have to worry about inrush currents and any external failure will affect the relay, not the module. It is less painful having to replace a relay than to replace a whole module. If you do not have much free space, you may consider using 700-HL... type relays which are terminal-block like.

Dear Harrison, I am attaching a speed measuring routing for low speeds. I use the method of measuring the time it takes to perform a single revolution so you have to activate a digital input every revolution. I use this routine to display a packing machine speed which goes from 12 to 120 cycles per minute. It is probably not as fast and accurate as you may wish but it works really fine for me. Anyway, it gives you a good idea of how to proceed and you may make it better or simply use a different approach. Hope this helps Bye chantecler (I apologize for my as-a-second-language English) P.S.: I utilize a ML 1200 instead of a ML 1100 because my emulator does not support the last one. LSM.RSS

Dear rdread, you don't need any sophisticated logic, just think about it, you have one pulse every 8 gallons so you only have to count the pulses and multiply that number eight times to know the total gallons. I wrote a speed measuring routine that you can use if you want to show the flow rate and also a counter for numbers as big as 1000000000 bye
