The following simple control panel will be used for this application:
The buttons and indicators are to operate as follows:
• The E-stop button—closed when pulled, and open when pushed—must be pulled in order for the
system to run. When pressed, the system will halt immediately.
• The normally-open Run button starts the extension and retraction cycle of the cylinders.
• The green Ready light indicates when power is supplied and the E-stop is not pushed.
• The green Complete light indicates when the cycle is completed.
• The red Error light indicates that the cylinders stopped because of an error (for example, perhaps
the cylinders lagged behind the target positions by too much).
1. Design the System
This application requires two axes, and we will assume that the position feedback is given by
magnetostrictive displacement transducers (MDT’s). Therefore, the appropriate module to use is
the RMC100-M1-DI/O.
The RMC controls based on the transducer or encoder counts received. However, counts rarely
correspond to meaningful engineering units. Therefore, the RMC allows the user to convert counts
into meaningful position units by using Scale and Offset parameters. Refer to RMCWin’s online
documentation for details. In this application, the position units used will be thousandths of an inch.
Therefore, speeds will be given in thousandths of an inch per second.
The following wiring diagram would allow the above control panel to work with the RMC in Input to
