其实好简单的，准备两个PUT就可以了。一个PUT给ID=1的时候用，另一个给ID=2的时候用。
再奉上CPU判断程序：
//~read cpu information
A #REQ
JCN h0a0
CALL "RDSYSST"
REQ :=#REQ
SZL_ID :=#SZL_ID
INDEX :=#INDEX
RET_VAL :=#SFC51_RET
BUSY :=#BUSY
SZL_HEADER:=#SSL_HEADER
DR :=#DR
h0a0: NOP 0
A #BUSY
JC g0a0
//Get Cpu master state
L P##DR
LAR1
A [AR1,P#2.4]
= #CPU0_MSTR
A [AR1,P#2.5]
= #CPU1_MSTR
//get cpu running infomation
A(
L #DR.Bz_cpu_0
L W#16#8

)
O
A(
L #DR.Bz_cpu_0

A(

A(
