RSLogix 5000 Programming Languages
RSLogix supports different programming languages. Using the right language for the right job can increase productivity, reduce complexity and maintenance costs. These languages are: Ladder Diagram (LD) Ladder logic was created such that most engineers and technicians would easily understand it and be able to maintain it. This was achieved by making the language similar to [...]
Seal-In Circuit Vs. Latch / Unlatch Sequence in PLC
Latch circuits and Seal-in circuits are types of electronics circuit that have two possible output states. The output is either true or false. They are mostly used as memory to store one bit of information. In PLCs this can be done by Latch / Unlatch configuration or by a Seal-In sequence. They both have their [...]
RSLogix 5000 Task Function
In RSLogix 5000 there are three main types of tasks: Continuous: It continuously occurs Event: It occurs only after certain events occur first Periodic: It occurs periodically Every task must have a main routine. Every routine can have a sub-routine and/or fault-routine. In RSLogix 5000, you can run up to 32 tasks with 0 to [...]
Lockout Tagout Safety Procedure
Lockout / Tagout is a safety procedure to safeguard employees from energized machinery and systems. This is standard procedure for field engineers working at plants and factories. Lockout / tagout is done to make sure the system is safe to work on and also let others know that someone is working on that particular device. [...]
