7.2.2 Structure of the Parameter Blocks
Tables 7-5, 7-7 and 7-9 show the data structures of the three parameter blocks
and how they must be transferred to the CM35 with SFC 55 calls or I/O di-
rect accesses.
The first word of the parameter blocks contains the control word. The required
assignment is entered as an initial value in the structures.
When I/O direct accesses are parameterized (only with SIMATIC S5), the
acceptance structures must be transferred after the data structures. See tables
7-6, 7-8 and 7-10. The required assignment of the acceptance structures is
entered as an initial value.
Adhere to the information in chapter 4.2 concerning transmission of the data.
Parameter block 1
contains:
-- The time base for timers 1 to 8
-- The factor for timers 1 and 2
