Figure 5-15 Basic Format of MMS Message
The socket data header identifies socket data, and any of three command/response sets
for read, write, and broadcast can be specified in MMS message transmission.
Auxiliary information indicates the transmitting source address of the command or
response received. The format is a combination of the upper and lower 8 bits of the class
C format of IP address (0xC001 to 0xC07F). Specify 0 for message transmission.
Invocation ID identifies command/response messages; enter a sequence number (serial
number) beginning with 1. The maximum is 0xFFFFFFFF, beyond which the count
restarts with 1. In case of command, it is necessary to set an ID different from the one set
for the preceding command. In case of response, it is necessary to set the same value as
that of the command received.
Status indicates the state of processing an added message in case of response
messages. Status is unused for command messages, in which case 0 must be set.
The value 0 indicates that the command has been processed normally and that a normal
response has been received. The value 1 indicates a response error on the part of the
opposite station. The value 2 indicates an error detected at the local station. When the
value is 1 or 2, an error code is set at the head of the response par to show the cause of
the error. (Figure 5-16)
