Manufacturer identifier
Explanation
These octets contain the manufacturer identifier:
FB09
for the Festo valve terminal types 03-05.
H
Header device-related diagnosis
Explanation
This octet represents the header for the
device diagnosis.
The valve terminal enters the value 8 in this
octet, i.e. 8 octets for device-related diagnosis
are transferred (incl. header octet). This value is
independent of the extent to which the valve ter-
minal is fitted with valves or other modules such
as analogue modules or AS-i master.
Structure of device-related diagnosis 1
Explanation
Logic "1":
error in AS-i bus
Logic "1":
AS-i nominal configuration does not correspond
to AS-i actual configuration
Logic "1": At least one electrical output short
circuited or overloaded. The faulty output can be
localized more closely with the "Device-related
diagnosis" 2 and 3.
Logic "1": AS-i supply voltage outside of tolerances
Voltage supply for sensors <10 V
Voltage supply for valve coils <21.6 V
Voltage supply for valve coils and
electrical outputs <10 V
Logic "1":
Short circuit of an analogue voltage input
or hardware error on analogue module
