Variables Access rights Description
sysLocation Read and write Location of the device; factory default: empty string.
The possible value is string with a maximum of 255 characters.
sysServices Read only Shows the functions (services) provided by the component according to the
ISO/OSI model. Each bit stands for one of seven OSI layers.
For the CP 1616/CP 1604, the "OPC Scout" program displays the value "74"
dec. (01001010 binary or 4A hex). Converted to a binary value, this means the
following decoded from the back:
Bit 2 set – Layer 2, primary switching
Bit 4 set – Layer 4, configuration with RFC 1006
Bit 7 set – Layer 7, PROFINET IO
Variables in the "Interfaces" directory
The following table shows several SNMP variables for monitoring the device status from the
"Interface" directory:
SNMP variable Access rights Description
ifDescr Read only Description of and possibly other information for a port.
The possible value is string with a maximum of 255 characters;
for example "SIEMENS", "SIMATIC NET", "CP1616", "<MLFB>",
"HW:<hardware version>", "FW:<firmware version>", "Fast Ethernet Port <port
number>".

•
Index 1 to 4: Port MAC address of the port
•
Index 5: MAC address for PROFINET IO
Data type: PhysAddress
