as shown below. ( For more details, refer to "[3] Descriptions of each command.")
PSEG : Program segment (corresponds to the file number.)
- Memory capacity varies with type of control module and memory module used. The
values above are the maximum values.
PADR : Program address
- Memory capacity varies with type of control module and memory module used. The
values above are the maximum values.
The program address is to be designated using PSEG and PADR.
Address 000000 to 076777(8) : PSEG = 8, PADR is the address expressed in hexa-
decimal notation.
Address 100000 to 176777(8) : PSEG = 9, PADR is the value in hexadecimal nota-
tion obtained by subtracting 100000(8) from the ad
dress.
[Example] Address 043256(8) : PSEG = 08(H), PADR= 46AE(H)
Address 153762(8) : PSEG= 09(H), PADR = 57F2(H)
DSEG : Data memory segment (corresponds to the file number.)
- Memory capacity varies with type of control module and memory module used. The
values above are the maximum values.
DADR : Data memory address (corresponds to the file number.)
