What are register symbols?
Register symbols are the symbols of registers containing data such as controller
parameter, operation status, alarm status, contact input, or error information in 16
bits or 1 bit.
When performing communication, registers are used as D-registers or I-relays.
D-register symbols
For some register symbols, the loop number, terminal area number, and group
number are indicated by adding the underscore (_) to the end of a parameter symbol.
If both the loop number and group number are added to a parameter symbol, they are
added to it in the order of _loop number and _group number.
xxxx_Ln_Y
Ln: loop number (L1 or L2)
Y: group number (1 to 8 (20) or 1 to 16, R)
xxxx_En
En: terminal area number (E1 or E3)
Example:
SP_L1_3: This means Loop-1 group-3 target setpoint.
PYS_2: This means group-2 PYS.
DI1.D_E1: This means E1-terminal area DI1.D.
