Motion synchronous actions
10.3 Main run variables for synchronized actions
The index <x> is used to specify the data block (access rights) and the value <number> to
specify the number of synchronized-action GUDs for each data type (REAL, INT, etc.). A 1-
dimensional array variable with the following naming scheme is then created in the relevant
data block for each data type.: SYG_<data type><access right>[<index>]:
Index
<x>
Block
0 SGUD
1 MGUD
2 UGUD
3 GUD4
4 GUD5
5 GUD6
6 GUD7
7 GUD8
8 GUD9
Where i = 0 to (<number> - 1)
Block: _N_DEF_DIR/_N_ ... _DEF, e.g for SGUD ⇒ _N_DEF_DIR/_N_SGUD_DEF
Properties
Synchronized-action GUD have the following properties:
• Synchronized-action GUD can be read and written in synchronized actions and part
programs/cycles.
• Synchronized-action GUD can be accessed via the OPI.
• Synchronized-action GUD is displayed on the HMI user interface in the "Parameters"
operating area.
• Synchronized-action GUD can be used on the HMI in the Wizard, in the variables view and
in the variables log.
• The array size for STRING type synchronized action GUD is set to a fixed value of 32 (31
characters + \0).
• Even if no definition files have been created manually for global user data (GUD),
synchronized-action GUD defined using machine data can be read in the corresponding
GUD block from the HMI.
NOTICE
User variables (GUD, PUD, LUD) can only be defined with the same name as
synchronized-action GUD (DEF ... SYG_xy) if no synchronized-action GUD has been
parameterized with the same name (MD18660 - MD18665). These user-defined items of
GUD cannot be used in synchronized actions.
