Q&A

EZ-ZONE® RMA PLUS Remote Access Module Q & A:

+ How does the RMA PLUS differ from the RMA?
The RMA PLUS offers faster discovery and transfer speeds, real-time communication via built-in Ethernet and USB, and enhanced data logging capabilities compared to the legacy RMA module.
 
+ Can I remove the SD card?
Yes, but only when the device is powered off. The SD card is not intended for removal during normal operation.
 
+ What is the storage size of the SD card?
The device ships with a standard 4GB card, or 16GB for data logging models. It is compatible with micro SDHC cards ranging from 4GB to 32GB.
 
+ What is the delay in reading parameters?

Assuming Modbus® TCP, the Ethernet response is typically less than one millisecond. The refresh rate of the data varies based on the system configuration.

+  What is the delay in writing parameters?

Again, assuming Modbus® TCP, the Ethernet response is typically less than one millisecond. Writes are handled before reads and are processed at the beginning of each device update.
