PLC Interview Questions Help
chickenkiller posted a topic in For Sale, Employment, Services or Wanted
Hello I am a Robot Programmer. Fortunately I would be beginning the PLC Programmer Interview Process. From Initial CV Screening and first round of Interview. Screening was easier. But unfortunately I am not good with PLC tech questions apart from that is involved with Robot Programming. I need a few questions to judge whether the applicant is faking his experience or does he has the qualities. If any PLC Programmers can help me, It would be a great help for me. Thank You -
I've set up a range of comments as well as their Chinese Translations in separate columns in GT Designer3. How do I go about putting a selector on the HMI to switch the languages from the HMI? I've been having trouble finding out a clear way to do this. The manual didn't seem to help. When previewing the HMI, I can manually select the 2 separate languages and everything goes according to plan.Has anyone had any experience with this that could help out a bit?

Hello I have been using GX Works 3 for a while now and I have discovered a couple of things, maybe bugs. I have not had any training for the software or hardware so maybe I did something wrong. 1 Labels. If you sort a global label table into any order other than the unsorted order that appears by default you are unable to create, delete or edit any labels. Our Mitsubishi representative discovered that if you click on the column header between 'Data Type' and 'Class' the order does not change but now editing is available. This, it turns out is a really bad idea. It seems the position the label was in when it was created is preserved, I think this is the unsorted order you get by default. If you sort the list and then delete a label it is possible that the label that should be in that position is also deleted. I have attached a small project to demonstrate this. Open the Global Labels notice the order they were created. Now change the sort order, click on the column header I described earlier to make them editable and then delete the label in position 1. For a while I thought this was the only problem but recently there has been a number of instances where I have created a label, given it a carefully selected address only to discover that it is being overwritten by another variable. I have not been able to work out exactly what is going on but I believe it is connected to the sort order of the labels. Also if you sort the order and change an address, have you changed the address of another label? The only solution I have found is to keep label tables very short so they are managable without having to sort the order, that is probably good practice anyway 1 Axis software limits. I have been using a number of axes in pairs, in incremental mode as caterpillar feeders, using FX5U-40SSC simple motion modules. I had a problem that the axis synchronised to follow would suddenly stop moving, the customer was having to power down the machine and start again. This problem persisted for months with Mitsubishi scratching their heads unable to fathom it out and ultimately stating that the problem must be in my code somewhere. It was suggested by the customer that it may be getting to a software limit, I showed the customer that the software limit was disabled in the setup and it was confirmed by Mitsubishi that it was not the problem. guess what, it is a problem. Once the actual position reached the limit of the double word memory it would stop moving. The solution is the take the servos out of synchronisation in order to set the position (datum) to zero every cycle. Unfortunately the drives do not always re-synch on the first attempt so you have to keep trying till it does, this now causes slight variations in cycle times but it works. Andy EDIT: I have since been informed that to disable the software limits they must be set to zero. This implies that the Enable/Disable setting is invalid and the limits are defaulted to their respective max values. Surely a default to zero would be more appropriate. Label Test.gx3

I'm sorry, guys, but I wouldn't be asking if I hadn't dedicated about 12 hours to this already. Long story short: ACS800 with RPBA-01 Profibus Adapter and RTAC-01 Pulse Encoder Interface. All we send to the drive (aside from CW permissives) is a position reference, and I believe the DriveAP functions execute how the drive will achieve that position. My final aim is to separate the encoder from going back to the drive, to instead going to a FM350-1 Counter module. I'm following someone elses work that is long gone, has been changed multiple times, and comments are almost non-existent. Where I'm stuck is understanding the data coming from the drive and being sent to it. PPO Type 5; DPV 0. In Step7, I have a DB for 20 bytes of data to drive and another DB for 20 bytes received from drive. I understand (with respect to data from drive) that it should be: SW; ACT; PZD3...PZD10 (10 x 2 byte Words). But, when I looked through all the settings in the group 51 parameters, the values in the form of (xxyy; index then subgroup; ex: 106 is parameter 1.06) don't seem to exist in the ACS800 Firmware manual. PZD 3 OUT: 7 --- PZD3 IN: 6 PZD 4 OUT: 8 --- PZD4 IN: 10 PZD 5 OUT: 0 --- PZD5 IN: 106 PZD 6 OUT: 0 --- PZD6 IN: 0 PZD 7 OUT: 0 --- PZD7 IN: 611 PZD 8 OUT: 0 --- PZD8 IN: 612 PZD 9 OUT: 0 --- PZD9 IN: 701 PZD 10 OUT: 0 --- PZD 10 IN: 706 The manual says parameter values 1-99 refer to a "Data Set" and each number specifies a certain word in a Data Set. For example, PZD3 IN: 6 refers to Data Set 2 Word 3, which is defined by paramater 92.03. But, that turns up something about short circuit protection, when what my DB value is displaying a distance (from a linear string pot encoder) that matches what the mill is actually at. The ACS800 manual says Data Set Actual Signal words are defined in Group 92. So I looked there: 92: DS Transmit (From Drive) --- 90: DS Receive (From PLC) 92.01: Status Word (Fixed) --- 90.01: 4501 92.02: 103 --- 90.02: 4309 92.03: 402 --- 90.03: 4505 92.04: 412 --- 90.04: 1 92.05:106 --- 90.05: 3 92.06: 0 Any help would be appreciated. Thank you.

Mitsubishi GOT27* Writing to Allen Bradley local tags (program tag)
Tuang posted a topic in Mitsubishi
Hi everyone, I just want to layout the structure of the question. I have a GOT2000 (GT27* series) that I have hooked up and communicating with an Allen-Bradley PLC. I have established connection and can pull out certain tags values from the PLC program in RSLogix 5000. While I can read the tag values, I cannot modify them (in certain conditions). So let say that I have a User-Defined Structure named "Smoke_Detector" and here are it's available members: Smoke_Detector: - ALARM (BOOL) - ON_TIME (DINT) * DINT in Allen-Bradley but Signed Binary 32 - Battery_Life (REAL) My question is that while I can read and display the tag and its members through the following: - LAMP for Smoke_Detector.ALARM - Numerical Display for both Smoke_Detector.ON_TIME and Smoke_Detector.Battery_Life But when I tried to modify the values via a Bit Switch or Numerical Input, it does not operate on them. However, if these tags are members are just standalone tags, meaning that they are not within a UDT in RSLogix 5000, then I can operate/ modify them just fine. Here are the things that I have tried: * Making sure that the permission are set to Read/ Write in RSLogix 5000 * Making sure that the tag definition in GT Designer 3 follows the structure where @[channel]:[Network #]:[Station #]::[Tag instance and member (e.g Smoke_detector is the instance and Alarm is member] Any possible insight and input are appreciate! -

Hi all ! I need a help about connection between mitsubishi GOT Simple series (gs2110) to kawasaki robot via crossed ethernet cable on tcp/ip protocol. I actually have a fx3g for main unit of my project, and also i have a kawasaki robot for slave unit. My purpose is basically to control both with HMI. I used RS422 between plc and got gs2112 and I want to use a crossed ethernet cable between robot and got but i did not communicate with ethernet even between pc and got. There is a manuel which I found on internet about GOT2000 Connection Manual (Microcomputers, MODBUS/Fieldbus Products, Peripherals) I think i need to work on microcomputer connection (ethernet) subject, what do you think about that ? I need all advices and ideas which come from you.

Hello, I am quite a newbie in PLC programming. I am trying to add a PID control function into a ladder program of FX3U PLC that was made by the person before me who used GX developer. I have read the manual, but still not sure if I understand it correctly or not. Please help me with questions below: 1. For parameters [S3]+1, how do I set the bit value? My understanding is that I need to align the bits I want, and then convert to Decimal number to set it, is this correct? i.e. If I need bit to be 0100001, do I set the parameter to 33? 2. How do I know if I am doing backward or forward operation? I think what I am doing is feedback control loop, does this mean it is a backward operation? 3. If I set auto tuning bit (parameter [S3]+1 bit#4) to 1, will this make the the program to run auto tune everytime I start the PID? 4. For parameter [S3]+22, [S3]+23 and [S3]+24, the manual said it will be occupied. Does this mean it will be preset by the program which I shouldn't mess with them? But how do I set the output upper and lower limit in [S3]+22 and [S3]+23? Also, I couldn't find any example of PID parameter setting in the manual. Not sure if I missed any important section in the manual. So please point out to me if there is any example. I also attached the manual on the PID page just for a quick reference. Thank you in advance for the help. FX3U Programming PID.pdf

Guys I'm having some troubles (as usual) I have datasheet for my profibus slave device (attached). I've probably done proper configuration in cx-configurator, I've got CIO 3200 (output) and 3300 (input) addresses for that communication. There's the question. How can I assign plc bit to specific valve position (its address)? I've made simple program where I can change 3200.00, 3200.01 etc. states but BF led on prm21 still flashing, and nothing happens.

Is there a Block Compare Instruction like the one in Omron PLC for Mitsubishi PLC? If the Omron PLC is BCMP (68), then what is the name of the instruction on the Mitsubishi PLC? I tried to use BKCMP in the Mitsubishi PLC, but the way it works is not the same as the one in Omron PLC

CX-Configurator CJ1W-PRM21 connection problems.
malyalewariat posted a topic in Other Omron Software
Hi again. I'm trying to make profibus connection between CJ2M and "Bosch Rexroth HF03 Manifold 12 Station DeviceNet Bus Box". After configuration I/O table in cx-Programmer and up[loading it to plc I've tried to configure settings in CX-Configurator. I've set up correct connection parameters of cj1w-prm profibus master. When I use "Test" option or just go online I get errors: "Communication Failure with unit" and "CX-server cound not be initialized". Am I missing CX-Server? I don't have this software installed on pc... When i try to use scan option i get another error: "Scanning failed, DTM returned an error for the request. Following DTM reported the error: Tag: CJ1W-PRM21 PROFIBUS Master Name:CJ1W-PRM21 PROFIBUS Master (Version V1.xx) Vendor OMRON Corporation.: Any advices? I can't find any good manual for CX-Configurator but i get CX-Profibus manual - is it interchangeable? Because i can see some same options in both. Regards! -
Mitsubishi FX5U Serial RS485 - non procedural communication
CrustyBurger posted a topic in Mitsubishi
Hello, I have managed to send output to a terminal using a serial channel. I have not been able to send data from the terminal to the Mitsubishi PLC. I am not using terminating resistors but I have a slow baud rate of 4800. I am just using regular wires (1.5mm square) . I think the hardware is okay as I can see the output from the PLC on the screen. Attached is the code. I just send from the terminal the character 22 every second, I hope this is not too incomplete to get some help. The plan I guess later is to interface with LabVIEW probably using Modbus but I need to try to get this working first. UL9.gx3 -
Hello everyone! Is there possibility to read words e.g. Name of alarm from the csv file or another file and save it in the PLC memory for further processing? It would be the best if the solution will matches to FX5 and IQ-R/F but it can be also for any of them. Thanks for help :)

Hi guys, I have been trying to sync up my RSLogix 5000 tag to GT Designer 3 (GTD3) objects but I noticed that GTD3 only recognize certain native data types from Allen Bradley Logix5572 Controller (Model 1756-L72). In the documentation that I found, it show that certain AB Native Tags are transferable to GTD3 Data Type (See the attached file "AB Tags to GTD3 Tags" ) One of the User-Defined Data Type from the RSLogix 5000 that I am trying to sync to Text Display Object in GTD3 is called "UDT_MY_CLTR_INFO" here is it's hierarchy of inheritance from RSLogix 5000 Name Force Mask Data Type MY_CLTR_INFO (...) UDT_MY_CLTR_INFO MY_CLTR_INFO.NAME STRING MY_CLTR_INFO.NAME.LENGTH DINT MY_CLTR_INFO.NAME.DATA SINT[82] In my exported tag which is a CSV file, it doesn't list the sub-classes MY_CLTR_INFO.NAME, MY_CLTR_INFO.NAME.LENGTH, and MY_CLTR_INFO.NAME.DATA, it would only list MY_CLTR_INFO. How do I link up my "Text Display" Object in GTD3 with the tag "MY_CLTR_INFO.NAME" whose Data Type is STRING and GTD3 does not have a STRING Data Type? I appreciate anyone that took their time to read my problem and any attempt to help me out. Thank you.

Hello, I would like to see your logical opinion about this situation and in which part of system where I need to find solution - software or in the physical field. Subject: Twelve old system based on Mitsubishi PLC AnS series, Profibus Here is pneumatic transport, with 5 lines, each line have a shredder and discharge valve. A few months ago, when line 1 works , display shows line 2 and vice versa, it was first problem, but the system was still working. From the last week system doesn't work. On the display appear line 3 in works, but system can not started. Alarm shows Double address (perhaps two valves have some address), Alarm still appear after reset and even all lines are turned off. What is your opinion where to find proble (PLC, I/O moduls, cables,...)

Mitsubishi PLC - The parameter Set Value is Out of Range - GX Works3
Bickers posted a topic in Mitsubishi
We have a PLC application that has been created in GXWorks3. We're using an IQ-F FX5U-32MR/DS with two analogue components: We're able to run our very simple program on the simulator and are having no issues, however when writing the changes to the PLC, we get the following error: We can't find where this parameter lives, and where to set it. According to the manuals, we think these means the set value is out of range, but we're not sure where the range is defined. What could be wrong with this parameter, and how do we change it? Thanks. -
Hello there, I've done some reading through GT Designer3 Version1 Screen Design Manual (Functions) and in chapter 30.3.6 - Program examples I've found functions used like: redraw_object(); d_circle(params); or acces of object params via script like my.active = 0; my.text_color = 0xE0; So, my question is, does anyone of you have/know about documentation for this advanced stuff, it could be real game changer for me. Thanks in advance for any reply

Dear All, We are in need of your expert opinion. One of the nodes of our Crane's Cabin gives a station failure problem, due to which whole Crane shuts down. we have done everything from replacing Dp connectors to changing Profi cables, swapping modules with other stations, changing Power supplies but the problem remains the same. Following are the system details, 1. CPU S7 319 F3 fail safe 2. IM 153 interface module 3. OLM module for signal conversion fibre to profibus from main CPU. We have several nodes after OLM but fault was persistent with 3 nodes. After comprehensive working, it came down to just one but still not diagnosed. I will also upload the diagnostic buffer if needed.

Help For communicating Mitsubishi Q-Series to Mitsubishi A700/A800 inverter via RS-485
Xhance posted a topic in Mitsubishi
I'm having trouble in finding a complete manual instruction and set-up on setting up a communication on a Q-series PLC to a inverter a700/a800 via RS-485. I have a manual for fx series, are the parameters the same as the fx series? how about the program, like starting or stopping the motor? Are they same or not? In the Q-series, do i leave switch-5 "station no. setting" blank? i just started this so i hope that i can make this work after new year. This is the manual for the fx-series plc====> http://www.automationsystemsandcontrols.net.au/PDF%27s%20Mitsubishi/Manuals/FPLC/FX%20SERIES%20USER%27S%20MANUAL%20-%20Data%20Communication%20Edition.pdf PS: I'm mostly self study because i don't have proper training yet and my school sucks. -
