Communication
Data exchange with the "FB_UA_RM" communication block on the AS level is performed via
the "UDT_UA_R_REQ_ST" (request) and "UDT_UA_R_ST" (feedback) structures.
For operator control and monitoring, signal exchange takes place between the AS and the OS
via the inputs/outputs of the "FB_STMAT" block.
Operator control and monitoring tags are used for data communication between the AS and
OS.
Corresponding scripts for the function block and its functionalities on the AS level are available
for handling on the OS level.
The "ALARM_8P" structure is used to implement data communication with the OS message
system.

Functions

Overview
The "FB_STMAT" block is used to search for materials in storage locations from the AS. You
specify the required material using a search filter defined in the AS. The "FB_UA_RM" block
sends the search query to the OS. The OS returns up to 10 storage locations matching the
search. In automatic mode, the storage location with the lowest material lot ID is selected. In
manual mode, the operator selects the storage location using the corresponding faceplate.
The data for the selected storage location are available in the AS at the outputs of the
"FB_STMAT" block. When export is started, the system checks the selected storage location
against the filter criteria and reserves the specified quantity in storage location content in the
user archive. This quantity reservation is canceled again once export is complete.
User-defined filter/sorting
User-defined filter / sorting can be activated for the search (EN_FILT = 1). The filter ID is
specified at the "LFILTER" input.
