  1. Hi, this is my problem, I created an app on FT Administration Console, in fact, one for network and one for local, I changed the connection to local on Log On FT, but, when I try to define the data points on Step 3 of configuration checklist, only shows me the network app, i select the app, after click OK, the FTTM freezes, anything else happens, I don´t know what am I doing wrong.  
  2. Hi I have a big issue with machine user access using loggin and password. There are different levels of login (operator, maintenance and admin) locked with physical key or password. The problem is that whenever any other user sees the password or got the key he can use it later. Is there another efficient way to lock the access and may be record who is logged when and how? Thanks  
  3. Hello everyone, I hope you are all doing very great, I'm new to Schneider PLCs and I have a project that I need to work on, so I will need your help with the following issues: *) How can one determine which Schneider PLC series is used if you only have a fuzzy picture of the PLC ?  *) I need to setup a historic of alarms, I have 13 PLCs, no connexion between them... I was thinking about creating a connexion between those PLCs and a database, so I need your help to determine a list of ALL the materials i will need (from cables to servers to a computer if necessary...) and some documentation on how that can be done... Thank you so much for helping me, Best regards
  4. Here is a recent post that I would like to share. Using Visual Basic 2015 we will log three holding registers from the PLC along with time and date into a Microsoft Access Database. We will log every minute into the database with the information that we collect from the PLC via Modbus TCP (Ethernet). All code will be done and shown so you can implement this in your application with different parameters. The information collected in the database can then be distributed or analyzed in the future. Visual Basic 2015 will be used with the EasyModbusTCP client/server library for .net. We will communicate to an Automation Direct – Do-More PLC. Using the free simulation software of the PLC Designer Software, we will retrieve three values of the Modbus Holding Registers using Modbus TCP. Once we have this information out of the programmable logic controller it will be placed in a Microsoft Access (2010) Database. This will be done by using a SQL command to insert the data. Read the rest of the post... Let me know what you think, Thank you Garry http://accautomation.ca/
  5. http://accautomation.ca/now-you-can-have-robust-data-logging-for-free-part-1/ YouTube overview: https://www.youtube.com/watch?v=6Xa2HYVOxE0 Robust PLC Data LoggerWith traditional loggers, software will read the memory of the PLC and store in a local computer. If the network stops or the PLC communication fails then the logging will stop.Creating a robust PLC data logger allows the communication to be stopped for a period of time without losing any of the data for collection. This is accomplished by storing the data locally on the PLC until communication is restored. All of the data is then read without loss. The amount of time that the connection can be lost will be dependent on the memory size of the PLC and the frequency of the data collected.This series will walk you through the steps to create and implement a robust PLC data logger using the following equipment and hardware.
