Chapter 9: Message transfers
(2)Memory address expression format
The format expressing memory address contained in the command (command text/response text) is as shown below. ( For more details, refer to "[3] Descriptions of each command.")
PSEG : Program segment (corresponds to the file number.)
| JW20H | JW30H | JW50H/70H/100H |
| |||
|
| ||
|
|
|
|
PSEG | 08(H) | 08(H), 09(H) | 08(H), 09(H) |
|
|
|
|
-Memory capacity varies with type of control module and memory module used. The values above are the maximum values.
PADR : Program address
| JW20H | JW30H | JW50H/70H/100H |

|
|
|
|
PADR | 0000 to 1DFF(H) | 0000 to 7DFF(H) | 0000 to 7DFF(H) |
|
|
|
|
-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 hexadecimal notation.
: PSEG = 9, PADR is the value in hexadecimal notation 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)
9 | DSEG : Data memory segment (corresponds to the file number.) |
