Busses
The RMA PLUS must be a master on a given bus to acquire data. It is a master by default on standards bus 1 and 2. It
may optionally be a master on Modbus® RTU (bus 4 and 5) if configured by the user.
Bus 0: Nothing
Disregard entry. This tells the file parser to disregard this entry / record.
Bus 1: Inter-Module Bus
This is the preferred bus for accessing data. It is the fastest and most efficient bus available. Any EZ-ZONE RM (9+)
module may be connected to this bus.
IMPORTANT: Do not attempt to access the Subroutine class (0x05) or Profile Step class (0x15) from the intermodule
bus. This will cause unpredictable results due to timing restrictions.
Bus 2: Standard Bus
This bus is used to access legacy EZ-ZONE devices that do not support intermodule bus: EZ-ZONE RM, PM (15+). Do
not use this bus if bus 1 is available. NOTE: The EZ-ZONE ST and RUI do not currently implement the required ser-
vices necessary to talk to the RMA PLUS.
Bus 4, 5: Modbus® RTU Master
If the model number is RMAP-2AXX-XXXX, then the device will have a card in the adjacent slot that provides two addi-
tional serial ports for connection to Modbus® RTU devices via RS-232 or RS-485. Bus 4 goes with Modbus® instance
6. Bus 5 goes with Modbus® instance 7.
Producer / Consumer Data
Producer / consumer data is used on intermodule bus. This subscription service allows devices (zones) to share data
with their network peers. It is analogous to multicast traffic in Ethernet in that it is produced by devices at regular inter-
vals and heard by all on the network, but only devices that subscribe to published data points consume these received
frames.This is the most efficient way to obtain data in the system and reduces the overhead for request frames,
queuing, data packing, etc.
This table documents the relationship between the source name (Text ID) and intermodule busaddress (Class ID, Mem-
ber ID) for all producers. Produced data points are outputs of software objects (function blocks).
