SI-INTERBUS User Guide
Issue Number: 1
If Pr
MM.006
shows a positive value, this value is dependent upon the Interbus network
communication speed, number of mappings and whether non-cyclic communications
are active or not.
12.4
SI-Interbus serial number
The SI-Interbus module serial number is a 10-digit decimal number loaded during
manufacture and cannot be changed. Two parameters are used to display the serial
number, Pr
MM.035
displays the last 8 digits and Pr
MM.055
displays the first 2 digits.
This parameter contains the last 8 digits of the serial number.
This parameter contains the first 2 digits of the serial number.
12.5
Cyclic data mapping status
The SI-Interbus mapping status parameter, Pr
MM.049
displays the status of the
mapping configuration as shown in
. If a mapping
error has been corrected, reset the SI-Interbus by setting Pr
MM.032
to On.

If the mapping configuration size has changed (Pr

),
then the module reset is insufficient to fully initialise the Interbus network and after saving
parameters, the module must be power-cycled.
Code
Meaning
Description
0
No error detected
No error detected with IN or OUT cyclic data mapping
configuration.
2
Direct data mapping
error
Non-cyclic data cannot be used when direct data mapping is
enabled.
3
Invalid non-cyclic mode An invalid non-cyclic mode has been selected in Pr
MM.005
.
5
Invalid mode value
The value entered in Pr
MM.005
is not supported.
104
Multiple non-cyclic
mapping error
A non-cyclic data mode has been mapped more than once in
the IN data mapping configuration parameters (Pr
MM.010
to
Pr
MM.019
).
110
Configuration read
error
An error has occurred reading the IN cyclic data mapping
configuration parameters (Pr
MM.010
to Pr
MM.019
) from the
drive.
