UserLimitDisable()

void UserLimitDisable

(

int32_t

number

)

Description:

UserLimitDisable disables the processing of a User Limit.

Parameters

number

the index of the User Limit (must be less than UserLimitCountMax)

Part of the User Limit method group.

Sample Code:

IO: User Limits

/*  This sample demonstrates how to configure a user limit triggered by a single digital input.
    When the input matches the specified value, the configured output is activated.
    Uses simulated IO with user buffer memory for demonstration purposes.
