Basic form of arithmetic function:
○○○○: Arithmetic function name (JCMD, JRSP, JSND, JRCV)
□□□□: First parameter (starting address of send or receive area)
△△△△: Second parameter (number of send/receive area bytes)
Enter a symbol (e.g., FW000) as the first parameter.
Set the starting address of the send or receive area.
Numeric data (e.g., extended memory address) cannot be entered directly.
Set the data length (number of bytes) of the send/receive area.
The second parameter setting range depends on the arithmetic function to be used.
JCMD 4 to 254 bytes
JRSP 4 to 254 bytes
JSND 4 to 516 bytes
JRCV 4 to 516 bytes
