The automation software house will be no longer in business? Microsd Card Reader Driver Windows 8. So, why should I put my hi-tech machinery in jeopardy? Your machinery supplier or system integrator does no longer support the software they developed and you are in trouble with S7 PLC programs where some blocks say 'block is protected'? You lost your.

From time to time, we'll run across situations where a client believes it is necessary to lock down code on a PLC. In some cases, there may be valuable intellectual property they would like to protect. In others, its purpose may be to prevent unauthorized modifications to safety-related code, or activation of disabled options. There may also be cases where it is necessary to interlock a PLC program to a specific memory card or CPU, especially in cases where there may be multiple, similar (but slightly different) machines. These machines may run unique software and by using the wrong code (or release) could cause risk to an operator or the machine itself.

Luckily, there are tools available within TIA Portal for all of these cases, and it doesn't take more than a few minutes to set them up. As I have a 1214C PLC sitting here on my lab bench, I'm going to use the S7-1200 platform as an example; however, these options could be enabled on other PLCs (such as the 1500 series) as well.

TIA Portal contains three different options for code protection: • Write/Read Protection • Know-how Protection • Copy Protection Let's take a look at each of these. Francesco Tristano Not For Piano Rarities more. Write/Read Protection Write/Read Protection is a CPU property: it can be assigned by viewing the properties of a device. This is done by opening a device in Device View, choosing the 'Properties' tab, and looking for 'Protection' under the 'General' tab. There are three options for Write/Read Protection you can choose from: 'No Protection' - This option is the standard and default behavior. With this setting, any user may connect to the PLC, read/write data, or upload/download a program to/from the PLC without any need for a password.

'Write Protection' - Selecting this option will prevent an unauthorized user from writing to the PLC. A user may connect to the PLC and upload a program or connect and go online with the PLC and monitor tag values with no need for a password. However, if a user wishes to download an update to the code on the PLC, download a new program, or edit/force tag value while online, a password will be required. With Write Protection enabled, a password is required to download to the PLC. With 'Write Protection' enabled, it is necessary to first enter the password before tag values may be forced or modified.
