Yes, it does. Both of the ladder program and the C program are executed as one of the INtime applications. More than one ladder language program can be executed on one PC. For example, the composition such as installing more than one ladder application to control more than one machine is possible. However, you have to be careful about the resource sharing and the competition of the external systems and data. For example, to control one digital output with the ladder applications and the C language applications, the process to exclude the competition contingent to multiprogramming is needed.
