Liam Bee

Liam Bee has worked in automation for over 16 years, after starting his career at 16 years old as an instrument technician in the water industry. He began his automation journey by maintaining PLCs and the instruments connected to them. He found very early on that he had an interest in PLCs and automation, taking the time to learn PLC programming in his own time, as well as exposing himself as much as possible to automation while working. After 8 years of working in maintenance, Liam started his own side business, providing bespoke controls using lower-range PLC solutions. This experience proved invaluable to his progression; he learned quickly, often through failure, and his knowledge of control design improved significantly. 12 years into his career, he moved roles again; this time, he was looking for something to fill knowledge gaps and target Siemens as he was yet to use Siemens extensively. Liam started at Aquabio Ltd and quickly found himself immersed in Siemens SIMATIC Manager and TIA Portal. Over the next 3 years, he worked hard to understand Siemens' tools and development environments, calling on knowledge from other PLC environments that he had previously worked with. Over his years working with automation, he has learned many different languages and development environments. He has worked with Siemens, Allen Bradley, Schneider, Mitsubishi, and a host of other PLC platforms, all of which have helped shape the design concepts that he uses today. Liam has also taught himself computer programming languages such as VBA, VBS, VB.NET, C#, Java, and more. Closing the space between IT and industrial automation is important as time moves forwards and he has always tried his hardest to be at the forefront of innovation.

Managing simulated inputs

S7-PLCSIM does not provide a solution for managing the simulation of input signals. It is up to the programmer to choose one of the following solutions:

  • Create a watch table and modify its input signals
  • Create an input mapping layer with dedicated simulation data

These two approaches both have strengths and weaknesses, but creating an input mapping layer is the correct choice when you wish to create standard control objects and UDTs.

Using watch tables to change inputs

In the Project tree area, open the Watch and force tables folder. Double-click the Add new watch table item; a new watch table called Watch table_1 will be created:

Figure 7.9 – The watch table view

The new watch table will open with no tags to be monitored. In the Address column, an Input address can be added that you can monitor.

Note

When input cards and remote I/O are added to a CPU in the Device configuration window, input memory...
