Process Control settings for devices are displayed in the details area when a device is selected in the table of devices, on the network interaction map, or on the topology map. If the process control settings are set for the device, the Process control tab in the details area contains the following information:
Device class – class of device from the list of device classes supported for Process Control.
Protocol – name of the utilized protocol. The following information is displayed for each protocol:
System commands – main settings for tracking system commands for a protocol. This field shows the total number of system commands for the protocol and the number of monitored system commands that will cause the application to register events if detected.
Address information – depending on the selected protocol, this field contains the IP address and port, MAC address or domain ID (for the IEC 61850: GOOSE protocol). If additional address spaces were added to the application, the specific address space must be indicated for an address (and the OSI model layers selected for address space rules must match the address).
Additional settings depending on the selected protocol. Additional settings are displayed if the application lets you configure more than system commands and address information for this protocol.
Examples:
When the Modbus TCP protocol is selected, the additional setting Reverse order of registers is also displayed. This setting lets you enable or disable support for an inverted sequence of registers (machine words) in 32-bit data values.
When the IEC 60870-5-101 protocol is selected, the following additional settings are displayed:
Two-byte ASDU address – lets you enable or disable two-byte addressing mode for application service data units (ASDU). If this mode is disabled, one-byte addressing is used.
Originator – lets you enable or disable the use of an additional byte for the originator's address in the data block ID.
Channel address block (bytes) – number of bytes in a data link layer address block.
Object address block (bytes) – number of bytes in an information object address block.
