Note
In the examples, the axes do not traverse in simulation mode!
Because “DBEX” is a retentive DB, it is initialized in the start/restart routine (OB
100). If this is not required, simply delete the initialization section of OB 100 (net-
work “DBEX Initialization”).
Basic example for setting the operating mode
This example is always required for sample applications 1 to 3.
Open the “ zDt13_02_FM353_EX ” or the “zDt13_03_FM353_EX“ example project
in the SIMATIC Manager with File > Open... > Projects . The block for this exam-
ple is FC 100.
You will find the signals in “DBEX”.
This example must always be called. It sets the operating modes according to the
user’s specifications, evaluates the mode status signals, and displays the current
mode. The checkback signals required for the examples will be copied into
“DBEX”.
In order to use the “Jog” or “Reference point approach” mode in Example 1, the
user has to set the relevant mode code in byte MODE_IN of “DBEX” (01 for “Jog”,
03 for “Reference point approach). When “Jog” mode is selected, mode parameter
01 (MODE_TYPE) is additionally set for activating speed level 1 in “Jog” mode.
Mode Code
Jog 01
Reference point approach 03
MDI 06
Auto 08
In Example 2, you must set “MDI” mode (mode coded in byte MODE_IN = 06).
In Example 3, you must set “Auto” mode (mode coded in byte MODE_IN = 08).
The active mode is displayed in byte MODE_OUT in the relevant code.
To restart the module (e.g. after diagnostic interrupt), bit RESET_AX must be set in
“DBEX”. The example will then set bit RESET_AX in “AW-DB”. A restart will be
initiated and bit RESET_AX reset in “DBEX”.
In order to work with the following examples, you must set the mode required for
each.
