TABLE OF CONTENTS The following is a list of Algorithms with the ability to interact automatically with each other to provide a complete controller. Depending on the combination of these algorithms and their specific use, controllers different in function and complexity can be configured.
| PIDN | Incremental real PID |
| PIDX | Incremental ideal PID |
| PV | PV and SP limits, mode, initialization, tracking, etc. |
| OP | PID-OP value, limits, mode, initialization, etc. |
| MODE | MODE handling between PID?, PV, OP, ALARM, etc. |
| STATUS | Controller status |
| ALARM | Controller alarm |
