The question we’ve received on a number of our content around the series is “how can I get started?”. Siemens PLCs - S7-1200 and S7-1500 Starter Kits We’ll be covering how to build your first project, how to configure PLC and HMI tags, how to establish communications to actual hardware and a simulator, how to write simple programs and download them onto the PLC. In this article, we’re kicking off a series of tutorials on how to build a project in TIA Portal. Our goal is to introduce our readers and viewers to various PLC and HMI platforms and give them an option to decide what’s the best solution for their manufacturing operations. The company has a market foothold in Europe and is growing in popularity in North America. Siemens is a world class manufacturer of various industrial hardware and software. The PLC log method works, but data backup and especially display can become a pain.Introduction to Siemens Programmable Logic Controllers There is a lot of info on SIOS about these topics, as Application Examples, FAQs and forum entries. using an internal BOOL tag that prevents a script from executing). ( you implement the 'disable' and 'activate' logging features, e.g.

Remove the USB, copy the files, re-insert it and activate logging again.

Disable logging and check USB is not in use using a script, e.g.

This is your custom-built table and yes it's the only way to do it unless you want to create a custom control and install it on the panel.

Display these internal HMI tags as IO fields on a Comfort panel screen.

Read the CSV file values according to your filter criteria (day, time range, batch ID, batch ID range, etc) using a VB script.There are application examples and forum entries on SIOS about this. Once a batch is complete, call a VB script that writes the values of these values to CSV file. You will have Comfort HMI tags representing each of these three values.Batch ID and timestamp can be stored in the PLC (if you want it to be retentive after a power cut), or in the HMI. daily, weekly or monthly, to minimize the risk of any single file becoming corrupt and you losing the data. Write the count value (generated in the PLC), the batch value and the timestamp to a CSV file on a USB drive inserted into the Comfort HMI, using VBScripts on the HMI.

There are a few ways to do this (yes, you can use PLC data logs and no they don't have to create a separate file for each batch), but I am posting here what I would do, because it's convenient for data backups, I have taken this approach before, and know it works.
