Transmission speed
500 kBit/s, 250 kBit/s, 125 kBit/s
Connector
Open Style connector, 5-pin
Operating modes
Bit strobe, polling, cyclic, „Change of State" (COS)
Process data width
96 bits (Standard configuration)
Process data format
Intel
Safety feature
The field bus nodes are equipped with a shutdown monitor so the power source
can interrupt the process if data transmission drops out. If there is no data trans-
mission within 700ms, all inputs and outputs are reset and the power source
goes into „Stop". Once data transmission has been re-established, the following
signals resume the process:
-
-
"Robot ready" signal
"Source error reset" signal
