The ’r;2’ in the Mode field indicates that the acceleration and deceleration are given as distances.
For details on the motion profile table, look up Profiles in the RMCWin online help.
This profile table and the tuning parameters can either be stored in the RMC’s Flash memory, or
stored in the Programmable Controller and downloaded using the Set Parameter commands.
We’ll assume they are stored in the Flash. See the Set Profile and Set Parameter topics in the
RMCWin online help for details on setting these values from the Programmable Controller.

5.1.6.8 Technical Brief: Using the RMC Discrete I/O Input to Event
Mode
Abstract
The RMC-DI/O is capable of sophisticated motion control using small and inexpensive
Programmable Controllers with simple discrete I/O. An RMC with a DI/O communications
interface is capable of four discrete I/O interfaces: Command Mode, Input to Event Mode, and
Parallel Position Mode. Of these four communication modes, Input to Event mode is the simplest
for many repetitive-process applications; many applications may not require a programmable
controller.
This technical brief will compare the four discrete I/O interfaces of the RMC100 product-line,
describe implementing Input to Event Mode, and finally provide a sample application using Input
to Event Mode.
DI/O Communication Mode Comparison
The following chart lists the advantages and disadvantages of each communication mode. Each
word or phrase in bold print appears in RMCWin’s online help index.
