5.3 Registers
5.3.1 Types of Registers
5-36
( 2 ) Function Registers
The following table shows the registers that can be used with each function.
Πn: Decimal number; h: Hexadecimal number
ΠB, W, L, F, and A: Data type (B: Bit, W: Integer, L: Double-length integer, F: Real number, A: Address. Refer to 5.3.2
Data Types.)
ΠSA, MA, IA, OA, DA, #A, and CA registers can be used within functions.

Z
Internal function
registers
ZB, ZW, ZL, ZFnnnnn
ZW00000 to
ZW00063
Internal registers unique to each function
Can be used for function internal process-
ing.
A
External function
registers
AB, AW, AL, AFhhhhh
AW00000 to
AW32767
External registers with the address input
value as the base address.
For linking with S, M, I, O, #, and
DAnnnnn.
# # registers
#B, #W, #L, #Fnnnnn
(#Annnnn) #W00000 to
#W16383
Call-only registers
Can be called only from the relevant func-
tion. The usage range is set by the user
using MPE720.
D D registers
DB, DW, DL, DFnnnnn
(DAnnnnn) DW00000 to
DW16383
Internal registers unique to each function.
Can be called only the relevant function.
The usage range is set by the user using
MPE720.
S System registers
SB, SW, SL, SFnnnnn
(SAnnnnn)
Same as DWG registers
These registers are shared by drawings and functions. Pay attention to how these
registers are to be used when calling the same function from a drawing of a dif-
ferent priority level.
M Data registers
MB, MW, ML,
MFnnnnn
(MAnnnnn)
I Input registers
IB, IW, IL, IFhhhh
(IAhhhh)
O Output registers
OB, OW, OL, OFhhhh
(OAhhhh)
C Constants registers
CB, CW, CL, CFhhhh
