Sending Commands from a PLC
RECV(098)
S: Remote node beginning word
D: Local beginning word
C: First word of control data (below)
Remote node number M (send source)
00 to 7E (Hex); 0 to 254
The range of node addresses is different for networks other than Ethernet.
96
With the RECV(098) instruction, the data in m number of words, starting from
the beginning word S at the remote node (node number M), is received at the
words starting from the beginning word D at the local node.
Number of reception words (m)
0001 to 03DE (Hex): 1 to 512 words
Destination network number
00 (Hex): Local network
01 to 7F (Hex): 1 to 127
Destination Unit address
00 (Hex):
10 to 1F: (Hex):
E1 (Hex):
FE (Hex):
Note The message services function does not guarantee that a message will reach
the destination node. A message may be lost during transmission due to fac-
tors such as noise. In order to prevent this from occurring when using mes-
sage services, it is common to set up retry processing at the node from which
instructions are sent. With the SEND(090), RECV(098), and CMND(490)
instructions, retry processing is executed automatically by specifying the num-
ber of retries, so specify a number other than 0.
