4-2-5 Master Errors (*_MstrErrSta)
One of the following Device Variables for CJ-series Unit is used to monitor the Master Errors from the
user program:
• WORD-type Device Variable for CJ-series Unit holding all switch functions contained in Master Err-
rors.
• BOOL-type Device Variable for CJ-series Unit separating functions per each switch contained in
Master Errors.
The Master Errors word collects all error information on the Unit master function. The status information
is collected in the Master Status word.
*_MstrDatXchgSta BOOL R Unit in Data
Exchange
TRUE:
Indicates that the Unit is in Data Exchange with at
least one allocated and enabled slave device.
FALSE:
Indicates that the Unit is not in Data Exchange
with at any of the allocated and enabled slave
devices.
*_MstrAutoClrEnblSta BOOL R Auto-CLEAR
enabled
TRUE:
Indicates that the Auto-CLEAR function has been
enabled. In case an error occurs in one of the allo-
cated slave devices during Data Exchange, this
function forces the Unit to the CLEAR mode, in
which it will force all allocated slave devices to a
Fail Safe mode.
FALSE:
Indicates the Auto-CLEAR function has been dis-
abled. If in this case an error occurs in an allo-
cated slave device, the PROFIBUS Master Unit
will continue Data Exchange with the remaining
slave devices.
*_MstrValidCfgSta BOOL R Unit contains a
valid configura-
tion
TRUE:
Indicates that the Unit contains a valid Configura-
tion. With this Configuration it can parameterize
the allocated slave devices and achieve Data
Exchange.
FALSE:
Indicates the Unit does not contain a valid Config-
uration or transfer of a new Configuration is in
progress.
