Example
• MES CHECK ($u0000, 10, 1)
The above program checks whether the V-Server in the computer specified in network table No.
10 is running. If the V-server is running, the returned value 1 is stored in memory at the return
address $u0000.
Supplementary information
• The value set as a return address must be different from the returned value.
• With $s514, you can set the execution style of the macro. For more information, refer to the V8
Series Connection Manual.
When a macro command is executed, if “1” (other than “0”) is set for $s514 while the V-Server is
not running, no response is given from the V-Server and the V8 will enter in the standby state. It is
recommended to execute this command when “0” is set for $s514.
• The result of the macro execution is stored in memory at $s515. For more information, refer to the
V8 Series Connection Manual.
• The returned value will not be placed at the address [F1] immediately. The [F1] address can be
monitored by the event timer macro, etc.
