5.4.1.2 User parameters
Standard specific parameters are followed by a number of user parameters dependent on the FD67
structure and extension. They first include parameters for the bus node and then parameter bytes for the
different modules. The sequence corresponds to the order in which the modules are connected to the bus
node. See chapter 8.
Parameterisation example : bus node and FD67DIOM121216.
Requirements :
You don't want the bus node to generate a diagnosis message if the actuator supply drops below 12 V
(Diagnosis „No Actuator supply“). If undervoltage of the actuator supply is monitored, no diagnosis
message will be generated, even if in case of an actuator supply cut-off caused for example by the
opening of a protection gate.
The I/O module must be parameterised as an Output at Pin 4 and as an Input with make function at Pin 2
(non-inverted input).
The user parameter string (all values in hexadecimal notation) looks like this :
