Diagnosis information
Diagnosis information of the SI unit is composed of 6 bytes standard diagnosis information and 7 bytes SI
unit status information, 13 bytes in total, as specified in PROFIBUS DP.
When the SI unit is in a non-standard state, it will send an error message to the master as diagnosis
information, and light up the DIA display.
SI unit status information is as follows.
Function Contents
Surveillance of Solenoid valve power
supply voltage It detects when the voltage of the solenoid valve lowers to approximately
19 V or less.
Input block open fuse surveillance
Detection of communication error in A to D on the input side due to the
broken fuse of the Input block.
Refer to PROFIBUS specifications and manual of the master, etc. for how to refer to diagnosis information
on the master.
The composition of diagnosis information is as follows. (The value when it is normal is indicated. "X" means
the value is changeable.)
Byte0: Station Status 1
Bit 7 0
0 0 0 0 X 0 0 0
Diag. Station_Non_Existent
“1” when SI unit is not
recognized by the master
Diag. Station_Not_Ready
“1” when the SI unit is not
ready for data transmission
Diag. Cfg_Fault
“1” when the SI unit
configuration information
transmitted from the master is
wrong
Diag. Ext
Indicates the status of
enhanced diagnosis region
(bytes 6 to 12)
Diag. Master_Lock
“1” when SI unit is set as the
other master
Diag. Prm_Fault
“1” when the parameter
regarding the SI unit is wrong
Diag.
Invalid_Slave_Response
“1” when the response from
the SI unit is wrong
Diag. Not_Support
“1” when the diagnosis is not
supported
