4.11.3 Trigger Register

The mailbox requests are initiated by the "trigger" register (INT) that is defined as
an input/output pin. The mailbox request is initiated after the application moves a
value of 1 to the trigger register.
The current value of all mailbox triggers for your application must be equal to 0 in
order to perform a mailbox request. If you are using more than one mailbox
function block, you must add program code to guarantee that this condition is
satisfied. Therefore, a mailbox function block is only allowed to send a new
mailbox request after the processor receives confirmation that the previous
mailbox request was acknowledged by the module. This condition is determined
by checking the status of all trigger registers (0=OK). It also prevents an attempt
to send more than one mailbox request in a single PLC scan.
The following table shows the trigger registers used for each mailbox function
block:
