Configuration Mode: This defines the Logicmaster configuration mode. MMS-Ethernet mode is required for Ethernet Interface firmware 1.15 or earlier.

Status Address: This is the location in PLC CPU memory of the sixteen (16) LAN

Interface Status (LIS) bits. To specify the location of the Channel Status bits, use the

Assign Channel Status Vector COMMREQ.

Note

Do not use the 16 bits assigned to the LIS bits for other purposes or your data will be overwritten.

Status Length: For MMS-Ethernet configuration mode, this is fixed at 16 bits.

Station Address: The Station address is the MAC address of the Ethernet Interface. If this field is left as all zeroes, the factory-assigned default MAC address (see the label on the Ethernet Interface's faceplate).

LAN Controller Load Source: This identifies where the Ethernet Interface should look for a GSM download. The choices are:

DSERIAL PORT - Only look for a download through the 9-pin serial port on the front of the Ethernet Interface.

DNETWORK - Only look for a download through the Ethernet network.

DPOLL ALL SOURCES - Alternate looking for a download from the serial port and from the Ethernet network.

LAN Online: This parameter allows the Ethernet Interface to access the Ethernet network (YES) or not (NO) after completing its power-up diagnostics. A setting of NO will prevent any network activity until a configuration with a YES setting is received by the Ethernet Interface.

Backplane Online: This parameter allows (YES) or disallows (NO) data transfer across the PLC VME backplane. A setting of NO will prevent any COMMREQs and prevent any host-requested data transfers from occurring until a configuration with a YES setting is received by the Ethernet Interface.

Network Load Address: This specifies the GSM ªgroupº to which this Ethernet Interface belongs. If there is only one GSM on the network, or if this Ethernet Interface will only be loaded serially, then this parameter should be left at the default value of all zeroes.
