This object is used to update settings of EX module parameters.
When this value is set to 1, the internal bus stops.
When this value is set to 0, the internal bus is enabled if there is consistency with EX module parameters.
Since the method for accessing this object is set to read-write in the [Slave setting] - [Expansion setting], it is allowed to input a value; however, changing the value does not affect anything. Do not change the initial value.
Even if the initial value is set to 1 for the object 3300h in the HTB unit, it is cleared to 0 when the HTB is booted up.
When the internal bus is stopped, all of the output for EX module is set to 0 and HTB output shifts to fallback state.
When extension bus stops in "action" state, unexpected actions may occur in the equipment resulting in damage and physical injury. If it is necessary to operate, set HTB in the "pre-action" state, or ensure physical and equipment safety before attempting other operations.
Failure to follow these instructions may result in serious injury or death.
