Request and Result Codes

D1945 Value Low Byte

Sample Program: Change Slave PI

This sample program changes the PI value of slave 1A to 3. To use the ASI command Change Slave PI, store new parame-

ter value 3 to D1943 and 1 to D1944 to designate the slave address using the MACRO instruction on

Write PI parameter "3" to slave 1A

To designate slave 31A, set 001F to D1944. For slave 1B, set 0021.

Parameters P3 through P0 are weighted as shown in the table below. When the PI parameter is set to 3, P3 and P2 are

turned off, and P1 and P0 are turned on.

Initial value at power up

Processing ASI command

Completed normally

(Executing conﬁguration)

Peripheral device failure

ASI command error

Impossible to execute

Execution resulting in error

While D1945 lower byte stores 01h, 02h, or 08h,

do not write any value to D1945, otherwise the ASI

command is not executed correctly.

The CPU module stores all values automatically,

except for 01h.

Command Data (Hexadecimal)

When input I0 turns on, the MACRO instruction stores hexa-

decimal values 0306, 0102, 0003, 0001, and 0001 to ﬁve data

registers D1941 through D1945.
