4.1 Address Confirmation
4.1.1 IP Address Confirmation
IP address confirmation
-
An individual IP address is necessary in order to connect the ET-LAN unit to an LAN environment.
-
Confirm the IP address with the person running the network system.
-
If two or more ET-LAN units have been installed on one backplane, individual IP addresses should be
allocated to each one.
Ethernet address confirmation
-
Individual Ethernet addresses for each unit are written to the internal EEPROM, and are also noted on
the plate affixed to the side of the unit.
-
This value can also be confirmed by checking the initial information notified area in the shared memory.
Router address confirmation
-
If the ET-LAN is communicating with another node or nodes through a router, the router IP address and
the sub-network address should be confirmed.
-
This is not necessary if communication is not being carried out with nodes of other networks through a
router.
Key Point:
If the network to which the ET-LAN unit is connected is completely independent, any IP address except
for 0000 0000H and FFFF FFFFH may be allocated.
4.1.2 MEWTOCOL Station Number Confirmation
MEWTOCOL Station Number Confirmation
-
This is used when communication destination nodes are specified with the computer link and data send
functions.
-
MEWTOCOL station numbers should be set in such a way that they do not overlap with the addresses
of other communication destination nodes.
-
Station numbers may be allocated within a range of 1 to 64. Allocating “0” will cause an error.
