SER, SERP: 9 steps
DSER, DSERP: 17 steps
Operands:
S
1
: Start device of data stack
S
2
: Device to be searched
D
: Start device for storing search result (occupies 5
consecutive devices)
n
: Stack length
Explanations:
1. SER instruction searches for the value stored in
S
2
from the data stack starting with
S
1
, with a stack length
n
.
The search results are stored in the 5 registers starting from
D
2.
D
stores the total of the matched results;
D+1
stores the No. of device storing the first matched result;
D+2
stores the No. of device storing the last matched result;
D+3
stores the No. of device storing the smallest value;
D+4
stores the No. of device storing the biggest value..
3. When SER is used as 16-bit instruction, Z device cannot be adopted; when SER is used as 32-bit instruction, V
device cannot be adopted.
4. If the instruction applied 32-bit instruction, operands
S
1
,
S
2
,
D
,
n
will specify 32-bit registers.
5. When specifying the bit device of KnX(Y/M/S), the starting No. should be a multiple of 16 in octal or decimal
format. For example, K1X0, K4Y20 (octal); K1M0, K4S16 (decimal).
6. The range of operand
n
:
n
= 1~256 (16-bit instruction),
n
= 1~128 (32-bit instruction)
Program Example:
1. When X0 = ON, the data stack D10~D19 are compared with D0 and the result is stored in D50~D54. If there is
no matched result, the content of D50~D52 will all be 0.
2. D53 and D54 store the location of the smallest and biggest value. When there are more than one smallest and
biggest values, the devices with bigger No. will be recorded.
