SMC–4000 User Manual
MW (Modbus Wait)
[Configuration]
DESCRIPTION:
The MW command sets the controller to wait for the ACK signal from a remote I/O device before going to
the next command. With this setting disabled, the controller will continue executing commands after an I/O
command that requires it to send a modbus packet. In this mode, the I/O state cannot be guaranteed.
Enabling this setting is the default, and is recommended. This is a configuration command and only needs to
be set once in the program. This configuration is not burnable, and is set to “enabled” at power up.
