RMC150 Startup Guide
Communications
Most PLCs or other host controllers can communicate with the RMC,
which includes reading status, writing values, and sending commands
to the RMC. The RMC150E supports Ethernet and PROFIBUS-DP.
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. See the Discrete I/O
topic in the RMCTools help for details.
Variables
Variables help 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 details on using variables, 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.
