Function Code 16: Write Registers
There are 21 registers in Function Code 16 that can be used to write to the M2A. This section only
describes Register 16 because it can be used to reset an alarm condition. For a complete description of
Function Code 16, see “Appendix C: Function Code 16 Registers” on page 60.
Register 16
Register 16 performs the same function as the ENTER button on the M2A. It is useful for remotely
silencing alarms. With the M2A in an alarm condition, bit [0] can be used to silence it.
NOTE:
Register 40 in Function Code 03, the remote configuration register, must be set to 1 in order
for Register 16 to work.
