Permanent Parameter (PP)
For AS ‐ Interface master module 1, data registers D1924 through D1939 are allocated to read and write the PP of each
slave. Like the PI, the PP is made up of four parameters: the P3, P2, P1, and P0. When auto configuration is executed, the
PI is copied to the PP and stored in the ROM of the AS ‐ Interface master module. When you execute manual configura ‐
tion, you can set the PP using the Configure Slave dialog box on
WindLDR
.
The ASI command Read PP can be used to read PP data to data registers D1924 through D1939. After changing the PP set ‐
tings, execute the ASI command Read PP, then you can use the updated PP data for program execution.
Changing ID1 Code of Slave 0
For AS ‐ Interface master module 1, data register D1940 is allocated to read and write the ID1 code of slave 0. To change
the slave 0 ID1 settings, store a required value in D1940 and execute the ASI command Write Slave 0 ID1. The ASI com ‐
mand Read Slave 0 ID1 can be used to read slave 0 ID1 data to data register D1940. After changing the slave 0 ID1 set ‐
tings, execute the ASI command Read Slave 0 ID1, then you can use the updated slave 0 ID1 data for program execution.
