Siemens SIMATIC S5 - User Data Blockassignment

R 02/92 Programming Instructions
Assignment of the parameters W, KB, and ST
Depending on the setting of parameter BEF, either the actual value, the initial setpoint or the final
setpoint are output at parameter W. If a setpoint needs to be supplied with an interrupt, this is
shown at parameter W 1 (setpoint with interrupt -t setting of bits 23 through 20: 0100). The bit
assignment looks like
this:
31

The track identifier bits are output at parameter KB. The setting is as follows:

The synchronization bits and interrupt bits are output at parameter ST:

9.3.5 User Data Block Assignment
If track setpoints are to be modified, they must be in the same user data block which was used for
parameter setting (see description for FB 156, PER:WPA). The same applies to the zero shift val-
ues during synchronizing.
Addressing the module (S5–155U)
For proper operation of the function block, the module “digital position decoder 1P 241” must be
addressed in the range from
KH = FF080 to KH = FF1 FE This corresponds to the P–range from
KH =
FF080 to KH = FFOFF (byte number 128to number255) and the Q–range from KH = FF1 00
to KH = FFIFF (byte number O to number 255).
