Amatrol’s PLC Graph Programming eBook Courseware for Siemens S7 Series PLCs adds to the S7300 Siemens PLC Troubleshooting Learning Systems to teach the fundamentals of the S7 Graph programming language. The S7 Graph programming language is a flow-chart based programming language used to program machines to perform sequential control applications for Siemens S7300 and S7400 PLC processors.
In sequential control, the machine performs a series of steps using elements such as transitions, conditions, and actions. The S7 Graph language is especially suited for programming sequentially controlled machines such as plastics injection molding or clamp and drill machines, to name a few. The programming language is becoming popular in Europe and is used on specialized machines brought to the US. Maintenance personnel in the US automotive and machining industries will need to understand the S7 Graph language in order to work on these machines.
