Permanent Configuration Data (PCD)
For AS ‐ Interface master module 1, data registers D1844 through D1907 are allocated to read and write the PCD of each
slave. Like the CDI, the PCD is made up of four codes: the ID code, I/O code, ID2 code, and ID1 code.
When auto configuration is executed, the CDI is copied to the PCD and stored in the ROM of the AS ‐ Interface master
module. When you execute manual configuration, you can set the PCD using the Configure Slave dialog box on WindLDR .
Set the PCD of each slave to the same value as its CDI. If the PCD is different from the CDI for a slave, then that slave does
not function correctly. Set FFFFh to the PCD of vacant slave numbers.
The ASI command Read PCD can be used to read the PCD data to data registers D1844 through D1907. Execute the ASI
command Read PCD before using the PCD data for program execution.
Parameter Image (PI)
For AS ‐ Interface master module 1, data registers D1908 through D1923 are allocated to read the PI of each slave. The PI is
made up of four parameters: the P3, P2, P1, and P0. The PI is the current slave parameter data collected by the AS ‐ Inter ‐
face master module at power ‐ up and stored in the AS ‐ Interface master module. To change the PI settings, use WindLDR
(Slave Status dialog box) or execute the ASI command Change Slave PI.
The ASI command Read PI can be used to read PI data to data registers D1908 through D1923. After changing the PI set ‐
tings, execute the ASI command Read PI, then you can use the updated PI data for program execution.
