Types of monitor

The following section give a short overview of the monitor types in the Factory Floor Status of the versiondog system. For all monitor types, a condition is to be understood as a condition for a warning (State: Alarm ).

The following applies:

• Condition fulfilled → State: Alarm
• Condition not fulfilled → State: OK

The monitor types are

Job results:

Description: Supervises if a job of the device resulted in a success or an error

Supervised attributes: Does not supervise the attributes of a device but the compare results of the job

Warning condition: Warns in the case of one or more of the compare results is “Error” or “Different”. (If both compare results are “Equal” or “Not present”, then the monitor state is OK )

Configurability: not configurable

Devices supported: All

Backup age:

Description: Shows how old the latest backup is

Warning conditions: Warns if the backup is older than the age defined in the job configuration, in the AdminClient. If this function is disabled for the job, then the monitor will always be in OK state

Configurability: The configuration of this value is done in the job configuration, in the AdminClient. There is no possibility to configure another value in the configuration dialog of the monitors

Devices supported: All

Cycle time:

Description: Supervises the length of the cycle time of the device

Supervised attributes: Makes a ratio between the longest measured cycle time and the cycle monitoring time

Warning condition: Warns if the longest measured cycle time higher is than a set percentage of the cycle monitoring time

Configurability: The percentage of the cycle monitoring time set as the warning limit can be configured in the configuration dialog of the monitors

Devices supported:

Siemens SIMATIC S7

Forced values:

Description: Supervises whether a device uses forced values or not

Supervised attributes:

All attributes showing if forced values are in use

Warning condition: Warns when at least one forced value was found

Configurability: not configurable

Devices supported:

• Siemens SIMATIC S7
• GE Proficy
• Schneider Unity
• RSLogix 5000

RAM use:

Description: Supervises the use of the RAM of a device

Supervised attributes: RAM

Warning condition: Warns when the RAM use is higher than a set value

Configurability: The limit value, over which a warning is issued, can be set in the configuration dialog of the monitors

Devices supported: Siemens SIMATIC S7

Battery:

Description: Supervises the charge of the battery

Supervised attributes: The S7 controller itself analyses the battery voltage and sends a boolean value. This value determines the monitor state

Warning condition: Warns when the battery charge is low

Configurability: not configurable

Devices supported: Siemens SIMATIC S7-300

Error display:

Description: Supervises the error display (LEDs) of the S7 CPU

Supervised attributes:

The following LEDs are supervised:

• SF
• INTF
• EXTF

Only the XML-attribute “Led_on” taken into consideration during the analyse; the “Led_blink” attribute is ignored for the determination of the monitor state

Warning condition: Warns when a LEDs sends an error

Configurability: not configurable

Devices supported: Siemens SIMATIC S7
