NETWORK READ/WRITE Instructions

Bit 15 of C+1 determines whether the instruction is for a SYSMAC NET Link
System or a SYSMAC LINK System.

seconds in 2-digit hexadecimal
without decimal point, i.e., 00

)
hex
Note: The response time will be 2
seconds if the limit is set to 0
There will be no time limit if the
time limit is set to FF
C+2
Source node number
(1 to 62 in 2-digit hexadecimal,
i.e., 01
hex
Note
1. The node number of the PC executing RECV(98) cannot be set.
2. Set the source node unit number to 00 when sending data to a PC. Settings
01 to 04 specify computer applications 1 to 4.
3. Indirectly Addressed Beginning Destination Flag:
The CV-series PC has a larger data area than the C-series PC. Therefore,
the beginning destination word of the destination node cannot be always
designated by the operand of the RECV instruction. If the beginning destina-
tion word cannot be designated, set the indirectly addressed beginning des-
tination flag to 1 (ON: indirect addressing), in which case the first operand
(S) will be the indirect beginning destination word, and it will be possible to
designate the beginning destination word (rightmost word) of the destina-
tion node in BCD with the word designated by the first operand (S).
