The module can use this IP Address when it wishes to resolve the IP Address for a domain name.
This parameter performs the same function as the Primary DNS parameter (
Primary DNS
( S.02.009 )), however the address specified in this parameter will be tried only when the Primary
DNS address is unsuccessful.
If DHCP is enabled ( DHCP Enable ( S.02.005 )) this parameter becomes read-only and, until a
secondary DNS address is allocated to the module, will display 0.0.0.0.
If DHCP is disabled the module will initialize, on reset or power cycle, with the secondary DNS
address stored for the parameter.
This parameter shows the 48-bit MAC address of the module.
This parameter enables the selection of the fieldbus protocol to have priority over all other
protocols. A tick period of 1 ms will be given to the highest priority fieldbus protocol, 5 ms to all
other fieldbus protocols (equal priority).
If no fieldbus protocol has been selected to have priority over others, all protocols will have equal
priority and a tick rate of 5 ms.
