VXi VT1529A/B 사용자 설명서

Identifiers are case sensitive. The names My_array and my_array reference 
different variables.

Channel identifiers appear as variable identifiers within the algorithm and 
have a fixed, reserved syntax. The identifiers I100 to I163 specify on-board 
input channel numbers. The identifiers I10000 to I15731 specify remote 
input channel numbers. The "I" must be upper case. They may only appear 
on the right side of an assignment operator. The identifiers O100 to O163 
specify output channel numbers. The "O" must be upper case. They can 
appear on either or both sides of the assignment operator.

Remote Scan Status identifiers appear as variable identifiers within the 
algorithm and have a fixed, reserved syntax. The identifiers S100, S101, 
S108, S109, S116, S117, S124, S125, S132, S133, S140, S141, S148, S149, 
S156 and S157 specify scan status variables that are linked to the on-board 
channels of VT1539A SCPs. These VT1539A SCP channels are in turn 
connected to Remote Signal Conditioning Units (RSCUs). The identifiers 
are treated like input channel specifiers and may only appear on the right 
side of an assignment operator. The "S" must be upper case.

When accessed, these identifiers return one of three values: 0=normal RSCU 
operation, 1=RSCU cable disconnected after INIT and 2=RSCU scan is out 
of synchronization (RSCU scan trigger problem during scan).

Trying to declare a variable with a channel or status identifier will generate 
an error.

The VT1422A's Algorithm Language supports the following operators: 

=

(assignment)

example;

c = 1.2345

+

(addition)

examples;

c = a + b

-

(subtraction)

c = a - b

*

(multiplication)

c =  a * b

/

(division)

c = a / b

-

(unary minus)

c = a + (-b)

+

(unary plus)

c = a + (+b)
