Timers are used in order to introduce delays in your code. Delays are just time intervals between two events. However in this case we...

Identifiers are lexical tokens that provide a way to reference language entities. These can be variables, types, labels, functions,...

Next I would like to talk about semantic code validation. This is also widely used in each and every development environment. It happens...

You've probably seen this kind of code assistance in many products. We take it for granted but if you try to do something like this...

We already know that a resource is assigned a "main" function block. But wait. It cannot work in isolation from other blocks right? How...

Ok. We already know SCL a little bit. Now how do I use it in Process Simulate? Where do I write the code? How do I organize my logic?...

Now that we know what a variable is imagine a use case where you need a number of them. Maybe ten, twenty or more? What would you do?...

SCL defines a set of primitive data types like any other strongly typed language. These represent the basic data containers that can be...

What is a script? A sequence of instructions (statements) executed one by one by the language interpreter. Each instruction gets you...

As we already know SCL scripts in Process Simulate are placed in the SCL Vault folder. Currently FBs, FCs and UDTs are supported. But how...

In Process Simulate SCL scripts are executed periodically. The execution rate is defined by the ‘LB Update Rate’ in CEE mode. In PLC mode...

Scripting has been around for quite long time. The script enables automation. In other words this is a way to execute code without...

Now that you know what the basic SCL building blocks are, it is time to make use of them in Process Simulate. FB, FC and UDT definitions...

User defined types (UDTs) allow for defining custom structures in SCL. The UDTs then can be used when declaring variables. Nested UDTs...

Structured Control Language (SCL) is a high-level textual programming language which derives its syntax from PASCAL. It is based on the...

The Function Block (FB) is just a function associated with some data. The data is stored in a Data Block (DB). In Process Simulate we...

Function (FC) syntax is quite similar to the FB syntax. Still there are some key differences. I'll talk about these in a minute. Example:...
