Symbols for enabled operations:

● Gray check mark: the OS operator cannot control this parameter at this time due to the
process

(6) Message suppression/delays
The message suppression indicates whether suppression of the associated message is

suppressed when the block is installed (all xx_MsgEn parameters are set to 1 by default).
Messages can only be output if limit monitoring of the additional analog value has been enabled.
Alarm delays are also displayed in this state; refer to the "Application of alarm delays" section
in the APL Online Help.
