1.5 Buffer description
MTC-04-NVT and the main module exchange information through the buffer (BFM), using
Modbus or MCbus. The cache that reads and writes properties can use MODBUS or MCBUS
instructions to write and read the contents of any cell in the BFM region. If the reserved cell is
read, it will get a value of 0. Save mark as Y represents the use of parameter save function, can be
written to flash, mark as N means can not be written to flash. The content of the BFM unit is as
follows:
1. Channel operation monitoring.
2. Channel feature setting.
