The mailbox function block contains inputs, outputs and input/output pins that
must be associated to specific variables.
The mailbox function blocks (except GetAlarm, which will be covered later)
require the usage of the following pins (common for all mailbox function blocks):

Description
Input Status pin. Must be associated to the imported variable
PTQPDPMV1_STATIN. It contains the status transferred from the
module allowing the mailbox function block to receive the
acknowledgment that the mailbox request was processed by the
module. It is used also to check if a new mailbox response is
available.
Note: The actual variable name corresponds with the module
name you configured in PCB. The data type names in these
examples use the default module name (PTQPDPMV1).
Input Mailbox pin. Must be associated to the imported variable
PTQPDPMV1_MAILIN. It contains the mailbox response
message that is handled by the function block according to its
mailbox ID.
Note: The actual variable name corresponds with the module
name you configured in PCB. The data type names in these
examples use the default module name (PTQPDPMV1).
Output Status pin. Must be associated to the imported variable
PTQPDPMV1_STATOUT. It is used to check if a new mailbox
response is available.
Note: The actual variable name corresponds with the module
name you configured in PCB. The data type names in these
examples use the default module name (PTQPDPMV1).
Output Mailbox pin. Must be associated to the imported variable
PTQPDPMV1_MAILOUT. This variable stores the mailbox output
variable that is updated from the function block when a new
mailbox request is performed to the module. It consists on an
array of words.
Note: The actual variable name corresponds with the module
name you configured in PCB. The data type names in these
examples use the default module name (PTQPDPMV1).
Move a value of 1 to this register to initiate the mailbox request. A
request can only be initiated if its current value is 0 and all
triggers for the other mailbox function blocks also have a value of
0. The actual name for this trigger register will be specific for each
mailbox function block.
