MESSAGE DESCRIPTION TROUBLESHOOTING
BROM This message will appear only when a MagneTek TI
Gateway ROM Configuration is used. If the firmware
does not see the correct configuration string in the
EPROM socket memory address, it ignores the con-
tents of the socket. If a valid configuration string
is found at the start of the EPROM, the remainder
of the EPROM configuration information is checked.
If the remaining configuration lines contain an
invalid base. slot, or module type, the firmware
displays the "BROM" on the 4 character display
and halts,
EARC This message is displayed during PLC Gateway
initialization if the MicroTrac Network Interface card
is not found. Initialization is not completed.

ECOM This message appears during operation if the Check the cabling between the
5136-TI card is not communicating with the 5136-TI card and the TI RBC
Texas Instruments PLC. Processor. Check that the cable is
connected on 5136-TI card.
EIVA When the PLC Gateway receives an allocation
message, it decodes the channel number into base
and slot numbers. If either of these numbers is
invalid, then this message is displayed. An alloca-
tion error message is returned to the sending node.
ELIA When the PLC Gateway receives a logical input
allocation message, this error message could appear
because the internal allocation table is full and
cannot handle another allocation. The allocation
table has room for 1024 allocations. A logical
allocation uses 1 element in the table.
