Receive LED
This LED reflects when data is being received on the second serial port (RS-
232/485).
State Description
Steady Off No power or no data being received.
Steady or Flickering Green Data is being received.
Note:
The Monitor Port does not affect any LEDs on the RMC70.
7.2.3.4. RMC75P CPU Module
PROFIBUS is a vendor-independent, open fieldbus standard for a wide range of applications in
manufacturing and factory automation. This high-speed fieldbus was designed especially for
communicating between programmable controllers and distributed I/O such as the RMC70
series motion controller.
Up to 126 nodes can be connected to a single network spanning up to 14km. The RMC75P
module supports data rates up to 12Mbaud, permitting high-speed on-the-fly downloads of
positions and parameters to the RMC module and high-speed uploads of motion profile and
status information to the host controller. The RMC75P’s PROFIBUS interface gives the
flexibility of several operating modes. Select the mode that best fits your application and
PROFIBUS master’s capabilities.
Features
• One PROFIBUS port
• One serial RS-232 Monitor Port
• 2 rotary switches to set the PROFIBUS station address.
Part Number
The part numbers of the RMC75P is RMC75P. Like all RMC70-series CPU modules, the
RMC75P can only be ordered with an axis module.
For example, RMC75P-MA2 is an RMC75P with a two-axis MA2 module.
