Figure 28: Network Adapter Diagnostic option-Extended Channel Specific Diagnostic
The list below indicates the channel specific diagnostic alarms that may be reported when
Extended Channel Specifc Diagnostics are enabled:
• Overload: error will be reported when overload is detected in the IO channel.
• Line break sensor supply: error will be reported when Sensor cable is
disconnected from the channel.
• External short-circuit: error will be reported when there is a short on the Power
supply of the channel.
• Line-break signal: error will be reported when Sensor cable is disconnected from
the channel.
• Lower limit exceeded- error will be reported when the Sensosor Input\Output
value is lower than the threshold.
• Upper limit exceeded- error will be reported when the Sensosor Input\Output
value is Higher than the threshold.
• Process alarm lost-This
• Short Circuit:- error wil be reported when there is a short on the Power supply of
the channel.
• Undervoltage:- error will be reported when there is a under voltage on the supply
of the channel.
• Overvoltage: error will be reported when there is a Over voltage on the supply of
the channel.
• Overtemperature:- error will be reported when there is a over tempaerature
caused on the internal component of the channel
• Power supply fault:-error will be reported when external power supply is not
connected to node.
• Parameter Error: will be reported when any error occurs in the configuration of
the module.
Note: Few of the alarms can be enabled or disabled in the configuration under “General
Parameters” tab of the module & some of the alarms are by default enabled in the
module itself and are not available for configuration
For example, suppose there is an RSTi-EP node connected & configured by a PACSystems
PROFINET Controller and the RSTi-EP node consists of one EP-3264 (4 channel Analog Input)
and one EP-4264 (4 channel Analog Output Module). The EP-3264 module is connected to
an analog sensor as shown in the figure below. On the PROFINET Network Adapter,
“Extended Channel Specific Diagnostics” are “enabled”. On the channel of EP-3264 module,
“Diagnostic Alarms” are “enabled”.
