I have an Omron NX PLC NX1p2 which Supports EtherCAT . also I have Balluff BNI00HA Ecat Block(IOlink Master). I have setup communications and connected a BNI004K balluff I/O device. I managed to get inputs and i can read it as well. but to set the pins of BNI004K as outputs i have to configure the module by accessing its Index and Subindex. I tried with IOLwrite Block but it says 16#4802 error. Also an Engineer from balluff suggested me to use CoE block but while reading the description is said CAN over EThercat. WHile my devices are IOLINK.. If Anyone can Help.Please. SS1 - Is the error I am getting on IOLink instruction SS2 - Is what i did. which is an IOlink Write block from Omron SS3 - is what balluff Engineer suggested.

Function blocks without defining Inputs and Outputs data type
BrunoRamos posted a topic in NJ Series / Sysmac Studio
Hi, I have quite a noobie question. I want to create a function block to do some simple operations on 2 variables. Both variables are In/Outs (see picture attached). How can I make this function accept variables regardless of the data type? Given these is just simple math I am able to use the same instructions in REAL, INT, UINT, etc. But, the function block only lets me assign one Data Type to the In/Out variables. -
Does anyone have some delta isp function blocks they can share with me please

hello Every one, I am using a CP1-L PLC and want to communicate to domino ax350i printer over TCP/IP socket programming. For socket programming, I used Omron Function Block CPU012_SendCommand. I defined network ID and node address. However, I am getting 0502 error which means routing table is not set yes. So, how can I set routing table for both devices?. my PLC on 192.168.250.1 and Printer is on 192.168.250.123 node 7000. Can any one suggest me best way to do. Thank you attached file is for what I did in setting and program for the communication.

Hello everybody, i have some uncertainties going through my head. i am fairly new in PLC word, graduated last year, last 12 month i did project on Siemens PLCs, but now i have to expand my view with Mitsubishi. 1. i am working on project with several conveyors. for each conveyor type i have FB fairly similar to my FB in siemens. For all conveyor i am using same sdt containing 32 bits. So a have array[0..20] of said sdt. But in fb i was not able to copy item from array, through input var containing index of that item to vocal variable, which i wanted to write back to the array at the end of fb. I tried different approach -> using item from array *** input/output. When monitoring item from array i can see, that variables i change in got2000 panel are in fact changing. But when i monitor fb itself, those same variables are not changing. i reworked this fb several times, for example when i found out that FB variables FB FXcpu cannot be set as retain so i would like to use it and i see no other way than make this fb work. :D 2. Is there possibility to us FB in another FB? I remember that i read some restriction about this, but now, i cannot find it. Thank you everybody for your responses

RSLogix5000 Transfer function Bumpless transfer between two inputs. If criteria or FLAG is true, then transfer from input-1 to input-2 at a prescribed ramp rate, and then release the output to match the selected input without rate restrictions. Issue: The issue is that upon the status of particular input (FLAG), the control valve demand jumps from 0 to whatever the output of the PID’s Low Select value is (maybe 50% or 80% or other). Request: Ideally, I would like to mimic or replicate the Transfer algorithms provided in other control systems, as described below . The TRANSFER algorithm performs a transfer between the two inputs. The output is equal to the IN2 input if the digital input FLAG is TRUE, and the IN1 input if the digital input FLAG is FALSE. The algorithm automatically performs a bumpless transfer between the track input and the selected input when a tracking request is removed. The algorithm ramps to the selected input (IN1 or IN2) at the specified track ramp rate (TRR1 or TRR2). Internal tracking may be selected to allow a bumpless transfer between IN1 and the IN2 inputs. Individual track ramp rates may be initialized to ramp from the IN1 to the IN2 and from the IN2 to the IN1. Attached is RSLogix5000 program "transfer.acd" Thanks.

Good day everyone, before I start asking my question, just want to let you all know that my knowledge with PLC is not that good. I'm still learning on how to do it. So currently I'm working on a project that trying to obtain data from Omron PLC. I was told that I can't touch the Omron PLC program or modify it. That Omron PLC is connected in an isolated network within a router. Other than adding Network Card on the device, can I use another PLC (any brands) to get the data from that Omron PLC through the router? The communication protocol using here is Ethernet. Can i just tapped into the network and take the data with that way? Or the other method I'm thinking is that, the Omron PLC will feed the data to a server, can I just obtain that data from server by using OPCUA? I heard there's some PLC that have the OPCUA function, I just make my PLC into the cilent and request the data of that Omron PLC from server through Ethernet. Is this possible? Please let me know whether my method works or not, thanks in advance guys!

I'm using simple function block, one input and one output, like in this example: Problem I have is how to call function block and use inverted (NOT) value , ie instead 5.01 I need to use NOT (5.01) . Of course I could create new symbols that are inverted values of actual inputs but i'm trying to avoid that, number of addresses is significant.

To calculate a walking or moving average I want to use WSFT and SUM in a function block. Does anybody have experience with this? The idea is to take a 1 hour average of a proces value and store this average value each hour. The software then have to calculate the walking or moving average over say 4 hours or 12 hours with a maxium of 24 hours. See attached files with logic but then not in a function block Walking_AVG.cxp Walking_AVG.opt Walking_AVG.bak

Can't monitor in simulator InOut variables in a Function Block
iaguilera posted a topic in NJ Series / Sysmac Studio
I can debug my plc app with simulator. I created some function block, and inside functionblock I can inspect in and out parameters, as well as local variables. But in/out parameters values are not shown. Any solution? Im using Sysmac Studio 1.29.2 and selected a NX PLC in my project. -
Studio 5000 EDS not registered in offline build
kdobsontn posted a topic in Allen Bradley / Rockwell Automation
Hi all, I've ran into an unusual situation where I could use some suggestions. I have an AB PLC working in the field, and an existing fixture that needs to be transferred from an Omron PLC into our AB. I have an integrator who did some offline development with a welder that uses Anybus communication. He sent a .ACD file to implement the logic from. The file has an Ethernet module configured but more importantly, it's showing EDS not registered. I've asked for the EDS he used, and none of them work when trying to register it via right-click and register. I can export the module, but it won't import into the current PLC program because there's no EDS (shows EDS error after the import). If I try to take the program that was sent to me online with the PLC, it will automatically upload and overwrite the build. I can't even open the properties of the module to see what the integrator did. The end goal is to have the offline developed module implemented into the current program, but it seems like everything I've tried to do has me against a wall. Is there a way to go online without uploading? Maybe there's a way to implement this I haven't learned yet? Any suggestions would be much appreciated, and if more information is needed, I'll be glad to provide it.

Hi everyone, first time posting here. I've got a problem with the Modbus MTCP-CP1L-Server fonction block. it worked fine for a good amount of time until i try to change an ethernet switch (not managed) on my network. at this moment the fonction block started to give me an error code (2211 ''unit is busy, can't execute''). So i put the old switch back again and I called Omron and they tell me to download Etherway and try to send some data to it but they can't do more. I did and BAM, it worked again. everything was fine for about a week and i was like, okay if etherway can ''solve my problem with the fonction block, i can put the new switch again, No I can't. It give me the same error, I try'd so many thing( put the old switch, everything that was possible in Etherway, change IP address, ethernet setting, reboot everything, connecting the unit direct to my PC. nothing can erase that error. Unit is an CP1L-EM with built-in Ethernet port did someone had have the same problem, or have any idea that can help me ? thank. Sorry for my poor English, its not my first language.

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.

Hi experts, please share the sample blocks for the EDITABLE TIMER block it should be editable from HMI(Siemens). And also motor run hour block. Actually i am having all blocks in tia v12 version and sadly i dont have the old software to convert it again. So please share the blocks that it shoud be work in TIA V14 for s7 1200 plc's. Please note that the blocks should use add instructions to calculate the time because i don't have much memory.

To those who don't know the GX Works2 compiler treats any function block referenced used in your code as a place to copy the entire set of code data into your program. Function block calls are not handled like pointers even though the should be. [You'll consume all your pointer space by thinking function blocks are great.]

PID Function Block: Error: Variable does not have enough size
ArttuJ posted a topic in CX-Programmer
Hey, I recently started trying my hand at creating function blocks. At the moment I'm trying to create a PID function block, however I keep getting this error: "ERROR: Variable does not have enough size." No idea why it does this. Can anyone help? -
Hello all. I posted earlier in the week regarding downloading new code to an Omron PLC, but I think the question was a bit vague. As a follow up, and hopefully to clarify, I have the following query. I have created an upgraded program which will be downloaded by field techs using memory cassettes. The revised area of code is essentially a Function Block which amends service lamp behaviour, and in creating it, I have amended the existing function block and added new Internal variables. Is there any way I can ensure that the new variables don''t over write or move the existing variables in the PLC, because this is what is happening when I download it. HELP!!!!!!!!!
