If you use the pointer to execute the double word operation,the minimum pointer
interval is 4.
If the value of the pointer is greater than the maximum value of the V memory,
program will generate errors.
The current value of the timer and counter is 16 bits,so the minimum pointer interval
is 2.
7.3 Bit, byte, word and double word access
Bit access
If you want to access a bit, you need to specify the address of the
bit.Address contains region identifier and byte number.Zero is the first
address of all data areas.The decimal point is used to separate the number
of bytes and the number of bits. The range of the number of the bits is
0~7. For example: M0.0
Byte, word and double word access
If you want to access byte, word or double word, you need to specify the
address.Address contains a region identifier, a letter and an address
number.
For example:
VB100 Access V memory address byte 100
VW100 Access V memory address bytes 100 and 101
VD100 Access V memory address bytes 100, 101, 102, and 103
