（
i
）
The variables beyond the amount are applicable.
（ ii ） The following operations may be performed between variables: ＋ , － , OR, XOR.

3.10.11 The Description of the P/S Alarm
1. Alarm No.004
The number or symbol is at the beginning of the program word instead of the address.
(For example): X1*1:
No.004 alarm will be given when “*” instead of the next address appears after X1.
2. Alarm No. 114
The formats other than <Formula> are incorrect. This type of alarm indicators up a lamp in the
following conditions:
(a) The characters following an address shall not be numerical values, • ,
－
, #, [,
＋
For example: XF1000 ；
XSIN [ 10 ]
；
(b) The formats other than IF (also called WHILE)[ <Formula> ΔΔ <Formula> ]
For example: IF [ #1 EQ #2 ] GOTO 10;
WHILE [ #1 SIN#2 ] DO1;
