  1. 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
  2. The 1980s brought the early adoption of the PC platform in automation systems and the first large projects, using the PCs to communicate with PLCs. In the following decades, supervisory and control systems technology evolved, creating several generations of software tools and automation products. A generation means an evolutionary step and a new platform, with a total change of the programming methods, user interfaces and paradigms, going beyond than the merely incremental improvements that are made during the maintenance life cycle of products; a new generation means renewing the internal architecture.

  4. Which software for what PLC?

    Hello All, Is there a table which shows which software will program which Siemens PLCs? I will, of course, be contacting the distributor, I just wanted to be forearmed. Thanks.
  5. Industrial automation

    Hello! I am doing a project for an industry to make the sensor tools wireless. I am new to PLC. is it possible to make the measuring tools with sensors wireless with PLC? does it work on a industry environment and what kind of technology is best for comminucation? wifi or bluetooth?   The existing sensors are connected with wires to a screen which says if the product is ok or not ok. I need to make this wireless. Any suggestions to make it easy?   please suggest me the boards to buy to try prototyping.
  6. I am trying to use FINS/UDP network to communicate with a Siemens device (at a customers site over seas from my home office), today I attempted to set up a SEND command based on information my customer received from a local Omron representative but had no luck.  I feel like I am missing something in a setting somewhere, does anyone have experience doing this?  I am using a CJ2M-CPU35's built in Ethernet IP port which is also communicating to 5 other Omron devices over Ethernet IP, so I am wondering if there is an issue having both networks. Thank you!
  7. Hello everybody. I need to learn PLC programming. I already have some experience with Ladder language and PLCSIM so now I need a real PLC to do more practice. I was going to buy the following unit: 6ES7211-1BE31-0XB0 http://www.eibmarkt.com/isroot/eibmarkt/Files/DatenblattE/NS6102812.pdf It has 6 Di, 4 DO (Relay) and 2 AI, that's more than enough for me to do some practice. Do you think it would be a good idea to buy it? Or maybe this PLC doesn't have some important component or device needed to work properly? (my company will give me the software). Thank you to anyone will help me. Have a nice day, Edoardo
  8. FX1N Counter operation

    We are working on a project that operates a set of 4 pneumatic solenoid cylinders using GX developer PLC type FX1N (C). when the desired sequence is selected, the cylinders operate in the order needed until they reach the counter. the counter value increases by 1 but does not run through the sequence again and cant move forward until the value of the counter is reached.  any help on this would be greatly appreciated.

  10. Gang, Hooking up an Automation Direct P2-32TD2P to an AC/DC LED and noticed the LED is always "on" a little bit. When the output is on, the LED is certainly on, but when the output is off the LED is still on by a fractional amount, not much but it's plainly noticeable the room lights are off. The CPU can be in Stop, no matter, power just has to be on. I think this has to do with the card's load disconnected error functionality. +24V and some fraction of amps is always present at the output whether the output is on or off. I talked with automation people at work who noted there is an Allen Bradley system that does the same thing, it caused them a problem, they had to use a relay or etc to make an off output actually be off. Has anyone dealt with this? I'm new to the Productivity software, but there doesn't seem to be a way to just turn it off in the IDE. It seems ridiculous to have to wire up transistors or relays just to have off be off. Thanks for any ideas.
  11. Hey guys,   I have worked on the FTView ME platform many of times.  I am now working on a FTView SE (Local Station) application, and I am having trouble connecting an Offline .ACD file to my program so that I can design.   If someone could help me with this it would be greatly appreciated.   Thanks in advance!
  12. I am using TIA Portal V14 to program a Siemens Mobile HMI (KTP900 Mobile). I would like to pull up a program 'signature' from the HMI that would allow me to verify that the code in the HMI is the correct version.  This would help prevent an accidental overwrite of old code, resulting in a single Mobile HMI that has differing code from several others that are also in use. The closest comparison would be a Safety Signature from a Safety PLC.  However, I just want to use a file checksum or similar variable that I can put on my screen. Any ideas?  I appreciate it. 
  13. All, I am using Keyence CV-X422A vision controller for my application. It is interfaced with Siemens S7-1500 PLC on PROFINET. I am able to communicate with Vision controller through PLC logic command and status IOs. There is some communication issue in updating the o/p values from Camera Controller. I have tried with & w/o Handshake Mode with these settings. The camera display shows the reject but camera never turns ON the NG Status o/p. I tried different things told by Keyence Tech support but none of them worked.  He told me to have you enable the “Result ACK Flag” in the bit allocation area and send  a signal to it. Then trigger it again with a no good part and see if that fixes the issue. I tried setting the “Result ACK Flag” to 1 after I get the “Command Complete Flag” for the trigger signal that I sent. Sometimes this works but still it is not reliable. Do I need to send only a pulse to “Result ACK Flag”? Anyone here has ever faced similar issue?  Thanks for your help. AP
  14. Greetings everyone, I have a Proface HMI(LT-4201TM Modular type DIO) connected to a siemens flow transmitter(MAG6000). Communication between these two devices is using modbus. The modbus register that im using to get the data/reading of a totalizer from siemens transmitter are 403022 and 403023. I managed to display the exact totalizer value from siemens transmitter on the Proface HMI screen. But I couldnt get the exact totalizer value at the ladder logic side, the value that i get at the ladder logic side seems like a raw value. For an example, the totalizer's value is 147083(real value), but at the ladder logic side the value for 403022=15598 and 403023=17316.   Can anyone guide me to solve this issue.   Thanks in advance.
  15. I'm being asked to come up with ways to upgrade an old 5/05 rack. A few years ago I thought I remembered Allen Bradley having a special rack that would allow a new processor control various old IO types. Does anyone remember the name of that system? and has anyone used it? We will probably replace with an Automation Direct PLC (per their request) but, want to offer an Allen Bradley solution as well      
  16. My issue is trying to receive data from a Datalogic PM9500 barcode scanner onto a Siemens ET200S (IM151-8 PN/DP) CPU using a serial interface card (6ES7 131-4BD01-0AB0) with the ASCII Protocol. The software that I'm using to program the PLC is TIA Portal V14. I made use of the built-in function block S_RCV to try and receive the data into a data block that I have created. I connected the Datalogic's base charger unit directly into the PLC's SI module. (I cut the DB9 plug off) So, Pin 5 (RXD) of the SI module is connected to the Tx wire (Brown) of the scanner, the Tx is also connected, as well as the ground, to the SI module, however, I only require the Rx. There is no flow control. Upon scanning a barcode, the Rx LED on the SI card flashes, indicating that something was received. I have tested the scanner using a terminal program called "Hercules", and I am receiving what I should be when I scan something. The parameters such as Parity, Stop Bits, and Baud Rate, etc, of the scanner corresponds to that of the SI module as well. I paramatized the S_RCV block as follows: 1.) EN_R is always ON. 2.) R is defaulted to the instance DB that was created with the function block's tag.  3.) LADDR  is set to "100" as that is the start address of my SI Module as defined in the device configuration. 4.) DB_NO is set to "2" as it is the number of the data block I created for storing the received data.  5.) DBB_NO is set to "0", which I understand to be the data blocks offset start point from where to start inputting the data. The rest of the NDR, ERROR, LEN, and STATUS outputs of the function block are also defaulted to the instance DB tags. I only want to see if I'm receiving the data from the barcode scanner into the datablock. I created an array of bytes and I also tried with characters  from 0 to 30 to store the data. As I mentioned, the problem comes when I'm trying to scan something, the RX LED on the SI module pulses, but when I monitor for any changes in the Function Block, as well as for any changes in the Datablock itself, nothing happens at all.  I don't know what If I'm missing something, this has been bugging me for some time now, I'm quite new to the whole programming scene, I would appreciate any help I could, get also I've attached the project file too. =)   Yumi_Panel.zap14

  20. Hello, I need to make an ethernet communication Siemens S7-300 <> Omron G9SP. The HW of the Siemens that i us are CPU 315 2DP and CP 343-1 Lean. I did try to follow the Omron manuals Z922 and Z924, but faced with some problems. First of all in Z924 there is no complete HW configuration of Siemens (communication configuration is missing). Also, formats of messages differ in both manuals. Maybe there is an Simatic Step 7 project example, that i could open with Simatic Step 7 manager to do a deeper investigation, or maybe somebody has a lot more experience in this case? Thank you in advance.   WBR @rturas
