GenComm Page 16 - Control Registers
1. Registers 0 to 7 contain flags that indicate the available system control functions, bit 1
corresponds to function code 0 etc. If a bit is set the corresponding function code is available.
2. One of the system control keys from the table below must be written into register 8 and its
ones-compliment written into register 9 with a single function 16 (write multiple registers) to
perform the specified system control function.
3. Writing any other value or using a function that is not available will return extended exception
code 7 (Illegal value written to register) and have no affect.
4. Function 34 ‘reset alarms’ is not the same as function 7. The former resets any alarm condition
codes that can be reset. The latter simulates a button, which may or may not exist on the
control unit, if it does not exist it will have no affect. If all alarm condition codes are able to be
reset the shutdown, electrical trip and warning alarm active flags (as appropriate) in page 3 will
consequently reset.
