Input Mailbox

This block contains the actual mailbox response sent by the PROFIBUS slave to

the module.

240 Words Block Format for Mailbox In Message (Input Image)

When the Block Transfer Size = 240, it takes only one Output blocks to form one

mailbox message request. There are ten block ID numbers to choose from and

there is no special significance to any particular number.

The customer's application logic may use any of the block IDs between 100 to

109 to send the mailbox request. As an acknowledgment that the request was

received, each Output block will be responded to with a corresponding Input

block containing the same ID number.

However, when the Input block containing the slave response to the request (if

any) is returned to the processor, it may or may not show an Input Block ID that

is the same as that contained in the original requesting Output block. In this case,

the Input block ID may be any number in the valid range of 100 to 109.
