Note
In this example, the maximum transmission delay is calculated for an instruction
receiving 256 words of data in a system with 32 nodes. Network specifics are
detailed below:
The maximum transmission delay is thus:
This section describes the format of commands that can be received from com-
puters or CV-series PCs and the responses that are returned. C-series SYS-
MAC LINK Units (except models C1000H-SLK21 and C200H-SLK21) can
receive CV-mode (FINS) commands, but cannot transmit commands in this
command/response format because they are not equipped with a COMMAND
instruction (CMND(194) in CV-series PCs).
Unless another format is specifically indicated, all commands and responses
are in hexadecimal. Commands that are sent to the PC CPU Unit differ from
those that are sent to the SYSMAC LINK Unit.
Commands have the following format:
Responses have the following format:
