Controller properties

The PLC has properties divided into groups:

Controller properties
Name Free definable controller name for easy user identification
Id Identification string
Device identifier MAC address of the device or other identifier
Assigned device type Platform type on which the runtime is operating - see attach PLC
History runtime identification String for unique identification of PLC as a data source for Mervis DB
Application version Application version eg 1.2
Stop on Excetion Exception of prohibited program run - see exceptions from running the program
Ignore Points Ignoring HW points see hw points
PLC connection parameters
User name, Password Credentials for SSCP connection
SSCP address Controller address on protocol SSCP, user for both TCP and serial communication
Connection type Select here how the PLC is connected to the IDE
•• Connection parameters Depend on Connection type; see data for TCP connection below
Server (TCP) PLC IP address to connect to

Baud rate (Serial) Baud rate
Parity (Serial) Parity
Data bits (Serial) Data bits
Stop bits (Serial) Stop bits

Every property in the property grid has, apart from its value, also a symbol indicating if the property is bound to the configuration or not. If the symbol is missing, the property is not depending on the configuration in any respect.

A mark indicates that a property depends on the configuration directly, and

  • has a default value (red mark with white square inside), or
  • its value is defined in the parent configuration (pink mark), or
  • its value is redefined in the current configuration (red mark).

A green mark indicates indirect dependency on a configuration - this means that the property does not influence any other settings or behaviour of the system, such as a Note (which is just a plain text).
