  2. HOW CAN I USE NETWORK I/O ON LADDER SOFTCOMFORT?

    Hi! I was doing an project using function block, but at one point it became too complex to use FBD so I would like to use ladder.  I'm using an ihm and that's why some inputs are of the network type, in FBD, it's easy to use the network i/o, but in ladder, the network inputs, where I receive data from the ihm, don't have outputs for me carry out the logic. How can i do this? USING FBD USING LADDER As you can see, theres no output on network analog input, on the digital to!

  6. Siemens S5-95U PLC and Battery Concern

    Hi All, We have a hydraulic press that is being controlled by Siemens S5-95U PLC . Lately the S5-95U has been randomly stopping during operation thus causing the hydraulic press to stop running. However the S5-95U instantly returns to RUN status after stopping. This is the first time it has happened after a decade of service. Prior to the random stops issue, around January 2021 the S5-95U completely stopped and the program in the RAM was erased so we had to replace the PLC battery and restore the program with our backup. Strangely, the PLC battery we replaced still had 3.4VDC upon checking. What's even more baffling is that even after we replaced the PLC battery with a new one,  Battery LED is still yellow although the program is still retained in the RAM. In summary, we have two concerns: 1. S5-95U randomly stops and resumes during operation ever since we were forced to replace the PLC battery and restore the program. 2. PLC battery has been replaced but the Battery LED is still yellow but the program is still retained in the RAM.   I have a suspicion that the two concerns I mentioned above are somehow connected but I lack the technical expertise to diagnose. I'm hoping someone can help me figure out our issue. Worst case, I think our S5-95U needs to be replaced.   Thanks,  
  7. MPI Connection problem

    Hi there. Recently I've experienced problems when connecting to a S7-300 PLC via MPI/PROFIBUS. I use a PG with CP5711 processor. The thing is that I'm able to connect when I plug the 6ES7901-0BF00-0AA0 cable (male to male) directly to the PLC connector, but when I try to do connect to a PLC that has any device connected to the DP port (let´s say an inverter or HMI) I get 33:17075 error. PG/PC Interface it's correct, in fact another PG with the same configuration is able to connect through the already connected DP device's cable. Station number and transmission rate is all correct.  So I tried the Simatic NET Diagnostics Test and I got error 0x0313 and since the mentioned parameters are correct I refered to this link:  How do Diagnostics and Remedy work in STEP 7 when an online connection with the CP... - ID: 11492532 - Industry Support Siemens Where they say the following:    I've searched for this readme file but can't find it, and there are no useful results when looking for it on internet.  Why am I able to connect directly to the PLC but not when another device is connected and I have to use the female connector of the DP connector itself? Should I try to reinstall CP5711 drivers? According to Windows, I got the last drivers for the CP.    Thanks in advance and I hope you can help me!

  9. Help Logo!8 to HMI Alarms

    I have an existing LOGO!8 and im adding a HMI (SImatic HMI KTP400). i want to bring up an alarm based on the status of a Flag in the PLC. i can see that i cannot address an alarm to a Bool Tag. so my question is how to i get it to work. Example. i have LOGO flag 1 (M0.0) and Flag 2 (M0.1) what to i need to do to make them into a WORD for the alarms.   Cheers

  11. Hi guys, Has anyone ever implemented a Siemens S7 RFID tag reader into a Mitsubishi PLC system? Is this something that is fairly supported to be able to achieve? Or a right pain to set up?
  12. Hi, I am new using SIEMENS. I am programming a KTP 400 Comfort. linked to a S7-1200. I would like to ask you how to do a solution I normally used in OMRON. There, I use an "indirect label" to index the line of a TXT file I want to show in a label of a button or indicator. This is similar to the "list of text" in TIA Portal. However, in OMRON I found the way to updated automatically the TXT file in the HMI using a computer but not using the software of OMRON. So, I would like to know how to do something similar using this SIEMENS HMI. I would like to show a label whose text changes according to the value of an index. However I would like to be able to change the file where the index points (TXT, CSV, etc) but not using TIA Portal. I would program a software to send the updated file automatically under FTP, or under the protocol you suggest me. Thank you very much.
  13. I have been working on a PLC project that requires sending ASCII commands/queries to an external pressure transducer using the Micro 850 PLC (2080-SERIALISOL module) via serial port communication (ASCII protocol) and in response the PLC would read pressure readings from the transducer. I was able to write a ladder logic program that reads ASCII code from the transducer and converts it into string and inversely converts string output from the computer to ASCII and sends it to the transducer. However, I am uncertain as to how I should send the command string from my computer so that the external transducer receives it, recognizes it after the <cr><lf> is encountered and sends a pressure reading. Any suggestions as to how I can type in commands from my computer and receive responses from the transducer?
  14. Siemens WinCC 7.0 SP3 SCADA Value Freezing

    Dear All, We are using Siemens WinCC 7.0 SP3 SCADA software. We are using two Redundant SCADA Computers that are communicating with PLC (CP-343 module) via Ethernet. One Ethernet cable from each PC is connected to Cisco Ethernet Switch and one Ethernet cable from the Cisco Switch is connected with CP-343 Siemens Ethernet Module.  The problem is after every 75 hours one PC value become still (Freeze).Only One system values freeze at a time. If i restart the system the problem is resolved. Please help to resolve this problem. Thanks  
  15. Dear Mr. PLC forum members, I am brand new to the world of PLC’s and I am looking for advice on PLC platform selection for a device prototype. The proposed PLC is for a “smart” hydroponic system. Please see system I/O and other parameters below. Parameter 1: Price - I am self-funding this so price of PLC and software is important. Happy to spend ~$2000 for PLC; I/O cards and related hardware. Total prototype cost is around $15,000 including PLC. Parameter 2: Availability & Support in Australia. Parameter 3:Newbie Friendly: I intend to code the PLC myself and have never coded a thing in my life before.  Parameter 4:Discrete Outputs: 11; Discrete Inputs: 0; Analog Outputs: 2-3; Analog Inputs: 9  Parameter 5: Capability to extend to IOT for remote access control and monitoring (via cellular or wifi router)   As you can see, this is a relatively simple automation project. All my research seems to point to Automation Direct’s BRX PLC but I just wanted to get some suggestions and feedback before purchasing. Anything else that might suit my needs? Any insight would be greatly appreciated. Bruce

  20. S7 200 SEG INSTRUCTION

    Hello guys. We are trying to replace a S7 200 PLC at our station with S7 1200.  We are reading the program on the S7 200 and recreating the same on the S7 1200. However, we have encountered the SEG  instruction used several times in the S7 200 (microwin) program. And the SEG instruction is not available in TIA Portal (we are using TIA 11) for the S7 1200. We have tried to read the s7 200 system manual but the explanation of the instruction is not sufficient to help recreate it. Could anyone know how we can create our own equivalent of the SEG instruction? If anyone has the SEG instruction already created as a program, it would be very helpful. Thank you.  
  21. Good day everyone!   I have some question relate with above subject. While i try make protocol for the CJ2M PLC.  i found out "Primary Expression (yN+x)" function but i cannt understand what`s this for. even i tried to find in the reference manual. i can not.  you can find it "Message Editor" -> "Message Variable" -> "Variable" sorry i tried to upload picture many times but it kept showing failed to upload.    hope so i could find the answer. thank you!
  22. Hi all  I need help with communication between Mitsubishi L06CPU-P with Siemens S7-1500 by Modbus TCP. It's necessary to send data from L06CPU to S7-1500, but I don't know anything about mitsubishi and gx works2.  Picked up some pics how I did it, but I didn't verified how it works. Can anybody help me with this? https://ibb.co/8KDmg5x https://ibb.co/Jm8shCx   edited: I also found LQnUDEModbusTCP_GW2_with_FC_V120 library, but how it works I dont know
  23. I am pretty new to the SCADA world. I wanted to know what are the advantages of using a paid proprietary SCADA software such as WinCC, Wonderware, cimplicity over free software such as OpenSCADA, OpenAPI, IndigoSCADA and so on. I have read, there are more layers of security in the paid one. What does that mean? What are the other main differences between the paid and free ones out there in the market?
  24. I have a purchased Machine that came with a Siemens LOGO 8.FSR PLC (Smart Relay). Generally we use Allen Bradley or Mitsubishi. Anyway, we need to communicate data between the LOGO and an Allen Bradley Compact Logix.  I do not desire to add an additional network to the AB but as best i can tell the LOGO is exclusively Modbus TCP/IP. Has anyone come across a similar situation?  I look online and did find an  Anybus module that claims to be able to link them together.  Looking for anyone who has faced this challenge and succeeded, or failed.   Thanks
  25. Good day all, I'm going to get a new Siemens PLC (model haven't decide) for a project using OPCUA server. I'm curious to know whether I made the right choice or not? Cause I planning to use that PLC to process some data that it got from OPCUA server. Can I know whether I can directly use Ethernet connection to take the data from server directly and fed it into my Siemens PLC? (I probably won't use the DI of the PLC for input data)
