IO axis bus
In order to use the IO axis bus, first decide whether the IO axis bus is to be used for transferring
controller errors in the network ("release cord" principle) or as a pure open-collector IO function. The
required function of the IO axis bus must then be set for all nodes in
• "Master/slave" function ("release cord" principle)
• In this setting, the IO axis bus only knows the two statuses "OK" and "Error".
• Each node connected to the IO axis bus can set the IO axis bus into the "Error" status.
• In the "Error" status, all nodes start their adjustable response, e.g. a synchronised braking of
the drive system or the master only brakes the network to standstill.
• The "Error" status can only be reset by the node defined as "master".
• The internal time base of the controllers can be synchronised via the IO axis bus.
• "IO" function
• With this setting, the IO axis bus is used as a pure IO transmission medium.
• Each node connected to the IO axis bus can transmit a TRUE signal to all nodes.
Short overview of the relevant parameters:
Stop!
The IO axis bus of the 8400 TopLine controller is not compatible to the state bus of the
9300/9400 device series due to different voltage levels!
