Command
Classification
Common
command
Subcommand
Description
• The ALM_CLR subcommand clears the alarm or warning
state. It changes the state of a slave station, but does
not eliminate the cause of the alarm or warning. ALM_-
CLR should be used to clear the state after the cause of
the alarm or warning has been eliminated.
• Confirm the completion of the subcommand execution
by checking that RSUBCMD = ALM_CLR (= 06h) and
SUB_STAT.SBCMDRDY = 1.
In the following cases, an alarm will occur and the sub-
command will not be executed.
• When the ALM_CLR_MOD data is invalid:
SUBCMD_ALM = 9h (A.94B)
• While editing using SigmaWin or digital operator:
SUBCMD_ALM = Ah (A.95A)
