Fieldbus interface faults
No. Cause
Remedy
70
The fieldbus function is not possible to perform, because
another field bus function is active at the same time
(/parallel function (IO) active and another parallel function
(IO)), e.g. “Measurement start” and “Program switching”.
Implement only one function.
71
The selected sensor is not available for the function.
Check whether the correct bit is selected via the
Fieldbus.
73
The activated fieldbus function (IO) is not possible or
disabled in the system configuration.
If the function is required, then it should be
selected under systems configuration.
76
The fieldbus function is not possible, because the
measuring mode is set to ”demo mode”.
Configure the parameter “measurement operation”
to “external continuous measurement” or “external
single measurement”.
77
The fieldbus function is not possible, because the menu
(keyboard operation) is operational.
Terminate the operation via the keyboard and
return the unit with the MENU key to its basic
mode.
78
The fieldbus function cannot be executed, because the
equipment detected double sheet (with configuration
”double sheet hold”).
Clear double sheet condition via fieldbus or via
keyboard.
79
The selected IP address / baud rate / Subnet / Gateway is
not conclusive.
Check IP-address / Baud rate / SubNet / Gateway
80
The inserted fieldbus coupler is defective.
Recycle power, if the fault persists send the
equipment to Roland Electronic Service
Department
81
The commands come too fast via the parameter channel.
Always wait for the results of the parameter
channel transmission before transferring new data.
82
The fieldbus function is not possible to perform, because a
parallel PLC function is active , for instance, measurement
start” via Fieldbus and in addition “measurement start” via
parallel IO.
Avoid simultaneous operation.
83
The parallel function (IO) is not possible to perform,
because a Fieldbus function is active.
84
Only L20-3-XX-S: While triggering calibration via interface
the range bit is not set.
Only L20-3-XX-S: Dynamic calibration, see
chapter 6.3.8. Set range bit.
88
The program number activated in the menu program
selection is > 255.
Select valid program number.
89
The fieldbus function cannot be executed, because the
parameter channel is active.
Close Parameter channel.
103
These faults match with the faults 3 resp.11-39 and may appear if data transmission from fieldbus via the
parameter channel is faulty.
