programmed in BASIC. See 4-1-2 Host Link Slave for details on Host Link
error handling.
Host Link Slave The Host Link Slave protocol will respond with the proper end code to the
Master when some error has been detected. No programmed error routine in
BASIC is necessary, all error handling is done by the Host Link Master.
DeviceNet Although most error handling will be at the DeviceNet master, the MC Unit as
DeviceNet slave has a status parameter. The FB_STATUS will return the sta-
tus of the Remote I/O Communication with the Master.
Please refer to Appendix C Programming Examples to find an implementation
of the master shell program. The master shell program is used for the config-
uration of the MC Unit and Servo Driver, for the control of the application pro-
gram tasks and for the continuous checking any error event that may occur. It
is strongly recommended to use this program or a similar program for every
application.
