Registers
9.4 Registers
These are elements which store a numerical value in 32 bits, their value remaining unalterable even
when the power supply to the system is cut off.
They do not have image values and are represented by the letter R, followed by the register number
it is desired to reference, for example R1, R25, R102, etc.
The PLC has the following registers:
The PLC will consider each value stored in each register as an integer with a sign, and can be within
±2147483647.
It is also possible to make reference to a BIT of the REGISTER by putting the letter B and the bit
number (0/31) in front of the selected register. For example:
B7R155 Refers to bit 7 of register 155.
The PLC considers bit 0 as being the one with least significance and bit 31 as being the one with
most significance.
The value stored in a register can be treated as being decimal, hexadecimal (preceded by "$"), binary
(preceded by "B") or in BCD. Example:
Decimal 156
Hexadecimal $9C
Binary B0000 0000 0000 0000 0000 0000 1001 1100
User registers R1 - R499
Registers for communication with the CNC R500 - R559
