I have a program to convert from Series Six to RX3i and the series six is using expanded addressing. I need help to convert this to standard addressing. I found a manual for this but I still can't figure it out. For example I have addresses I1+0201 I1+0203 I1+0205 I1+0206 I1+0207 and need to represent them in RX3i. I attached the 3 page "manual" on extended I/O for reference. Thank you in advance for looking at this Series 6 Expanded IO Addressing.pdf

I am working on something different. I have a Signal Speaker that uses binary inputs to play a certain song based on source configuration. I have to send 24v to the inputs of the speaker. I have 5 of them with 30 different configurations. I am currently trying to do this in ladder logic, RSLogix 5000. Steps done. 1. Assigned the 6 outputs tag names. This is so that I can shift the program to other machines if I have to and I just need to change the slot location, or if I have an output go bad I can move it with ease. This works. 2. I created the 30 lines of 5 columns to match the binary method. This works. a. I can manually toggle the output to cycle thru the binary table. 3. Currently working on the logic that when a particular alarm is activated... I turn on the outputs needed to match the binary table. The problem is destructive bit reference on the coils. I was researching some but don't know what direction to go. How can I call the same output on different rungs? I have attached the .L5X to show what I have programmed. 4. I know the first rungs are wrong. That is what I am trying to fix. 5. Would there be a better way to address this, if so how? Any help would be greatly appreciated.

Hello all. I have a program which has 8 function blocks. I recently added extra functionality to one of the programs (not the function blocks). I added the new variables to the global symbols table and added the new code, but when I compiled the new code, the variable addresses in three of the function blocks had changed. This is a problem, because we use memory cassettes to download new versions of code, so when the new version is downloaded to a machine in some far flung part of the world, these variables will be overwritten (they are hours run variable, so are important for servicing purposes). My understanding is that CX assign's variable addresses in Function Blocks and we have no control over this. Bit if I only added variables to the Global symbol table, why are the FB addresses affected?? Any input appreciated.

Trying connect baumer EAL 580... Ethhercat absolute encoder with Beckhoff C6015. Ethercat connection is From PLC to EL6695 module(This module is connected to KUKA robot for mater to master communication) and from Out port of EL6695 to In port of Baumer Encoder. It is not getting scanned nor manually appended. But when i connect it directly to PLC it works fine(gets scanned). Any solution?

Good day. I'm using 1756 L71S GuardLogix Integrated Safety Controller with Studio 5000 v28. My controller is connected to a third party software through ethernet connection, it simulates my project hardware and provides all the signals to my PLC. To know all the hardware signallocation at PLC memory, it uses a Tag export file provided by Studio 5000. In other PLCs, when you declare a variable as hardware input, you have to select in which address from the memory you want this input to be read, something like "Bit Input 0.0". But in AB this step is skipped, that is all addresses are managed by Studio5000 and hidden from the user. Is there any configuration at Studio 5000 that let me assign or at least see this addresses? Normally I would prefer my tags addresses to be hidden, but in this specific case it is more useful to know memory addresses.

absolute motion servo motor and emergency stop
papaya posted a topic in Allen Bradley / Rockwell Automation
Bonjour, Hello, I use a l33erm automaton and a Kinetix servo motor . This servo motor drives an engine with a chain moving in steps of 100 millimetres (there are 15 steps on the chain ) At each top of a cell this motor advances by 100 millimetre. in reality it advances from about 0 to about 100. Sometimes it is 100,002 times to 99,997 (this is important further) and when I give it a top it goes back to about 100 (100,003 times to 99,996) And so on and so forth up to no problem, I use a MAM with an absolute type of movement. It works. However, this does not work any more after a rearmament following an emergency shutdown. if it is a 100,002 no problem at the next top the chain advances one step But when the engine is shut down at 99,997 and I give it the order to go to 100 it advances only by 0,003. This only happens after an emergency stop (or door opening). Thank you for the help you can give me excuse my English this is a machine translation Un séjour sans faille -
Modbus addressing in Weintek HMI to poll data from Temperature sensor through RS485. In my system i have connected Temperature sensor to I/O Scanner has output in terms of RS-485 which directly connected to COM3 Port pin. No. 6 (as Negative) & 9 (as Positive) of HMI (Model No: MT8071iE) and HMI connected to PC via ETHERNET. I want to read temp on HMI screen via MODBUS protocol. So, can you please provide me instruction about addressing of MODBUS register in Easy-Builder Software so can read data of corresponding register. Because when i do compile i got an error like " Device no Response". I hope i will get reply from your side as Fast as possible to overcome this problem. Thank you.

Hello. How can I get bit addressing of defined variable in function block? For example: - I define variable type DUINT with name Double_VarI_INT. - I want to get or set one bit out of it (its double word). - If I use Double_VarI_INT.0 I got error. Best regards.

Hi, I'm attempting to convert some old Siemens workshop 505 code to control logix and i have basically no siemens experience at all and i'm confused as to how to tell what actual output card X1 or X2085 is referencing?? same with inputs.

Hello all, i'm looking at installing a completely new network for our PLC system, using a ring topology. at the same time i would like to incorporate the IP cameras and VOIP into the same network. each system is on a different sub net, PLC = x.x.1.x, Cameras= x.x.2.x, VOIP= x.x.3.x estimated camera traffic will be 25 Mbps, PLC 10 Mbps, VOIP no more than 1 Mbps switches would be capable of 100 Mbps question: managed or un-managed switches? if it is possible to use un-managed without affecting operations then this would be a massive cost saving please only comment if you have practical experience implementing this many thanks Dan

Hello all, Let me start by saying that although I have been working with PLCs for 20+ years I am very (as in brand) new to the Siemens world (my wheelhouse is AB). That being said I have a Siemens S7-1500 (1511 specifically) CPU with a couple of SICK multi-turn Profi-Net encoders (AFM60A-S4NB018x12) that I need to talk to. - I am using TIA v13 with all of the updates. - I have the GSD file from SICK for the encoder. - I have no clue what I am doing - I can see the encoder values update in the watch table as I move the encoder. All fine and dandy so far... Here's where the white flag is going up.... - I am of the belief that there are existing function blocks out there 'somewhere' that can read and write to the base parameters. I have contacted our local rep who deferred me to SICK. I have emailed and left messages with them and have not gotten a return anything thus far. Here's our application... We are attaching each encoder to its own rotary gear mechanism. The rotary will need to turn in the CW direction approximately 400 degrees then return to its start point by rotating in the CCW direction by the same amount. If/When production/maintenance needs to 'rehome' the assembly, the expectation is that they 'pin' the drive in a known location then a bit would be set within the CPU that would assign a specific value to the encoder's actual position. In the SICK manual (8015078/YIX6/2015-01-16) on page 31 (section 3.6.3) there is reference to Preset control. This is what I believe we need to perform the aforementioned function. Does anyone have any examples that they could share on how to read/write to these encoders by use of a Function Block or other? Relatively desperate for help at this point. Can post test code if need be. Thank you in advance, TLAF

I have a PLC that i just had to replace the old PLC was an Omron FA-350A the new PLC is a CMP1A-40CDR-A-V1. The programs are almost identical however there are some I/O changes that will need made. I am used to allen bradley PLC's and this is my first time using CX-Programmer. The PLC came preloaded with what was supposed to be the correct program although almost all of the I/O was programmed to the same addresses. I have no idea how the Addresses are structured. Would anyone be able to explain them or point me to a resource. There are also some 200.XX addresses are those bit storage locations? Thank you, Mike

Point IO input/output address assignment
python01 posted a topic in Allen Bradley / Rockwell Automation
I have never worked with Point IO and wonder how the addressing for inputs and outputs are assigned? Is there a way to tell the PLC what addresses should be used for IO on the remote? I am planning to use the following: 1734-AENT 1734-OW4 1734-OW4 1734-IE4C
