Communications

Most PLCs or other host controllers can communicate with the RMC,

which includes reading status, writing values, and sending commands.

The RMC70 supports Ethernet, PROFIBUS-DP, or serial RS-232/485.

See the Communications section of the RMCTools help for more

detailed information.

Discrete I/O

Discrete I/O augments the communications of the RMC. Discrete I/O is

often faster than the communications, and is therefore well-suited for

starting a sequence in the RMC at a specific time. Up to 32 discrete I/O

can be added to the RMC70. Each I/O point is individually configurable

in software as inputs or outputs. See the Discrete I/O topic in the

RMCTools help for details.

Variables

Variables make the User Programs very flexible and easy to maintain.

Variables can be used to effortlessly change programs and easily

modify User Program parameters via a PLC. Variables can also be used

to store data. For more details see the Variables topic in the help.

Program Triggers

Use the Program Triggers to start User Programs based on conditions

defined by the user. For example,

 Start a User Program by writing to an RMC variable from a PLC.

 Start a User Program when a discrete input turns on.

 Automatically start a User Program when the RMC starts up.

 When an error condition occurs, automatically start a User

Program to handle it.

See the Program Triggers topic in the RMCTools help for details.
