2.3.1 [MODULE]
The module section contains the data that applies to the whole module and includes the
backplane data transfer parameters.
The following table describes the content of this section:
[SECTION]/Item
Range
Description
[MODULE]
Header for module section.
Module Name:
Up to 80 characters
This field contains a user assigned name for the
module.
Read Register Start:
0 to 3999
This parameter sets the starting register in the
modules database where data will be transferred
from the module to the processor.
Read Register Count:
0 to 4000
This parameter sets the number of registers to
transfer from the module to the processor.
Write Register Start:
0 to 3999
This parameter specifies the starting register in
the module where to place data received from the
processor.
Write Register Count:
0 to 4000
This parameter specifies the number of registers
to accept from the processor.
Error/Status Offset:
-1 or 0 to 3935
This parameter defines the database location
where the module status data will be stored. If set
to -1, data not placed in database.
Failure Flag Count:
0 to 65535
This parameter specifies the number of
successive transfer errors that must occur before
the communication ports are shut down. If the
parameter is set to 0, the communication ports
will continue to operate under all conditions. If the
value is set larger than 0 (1 to 65535),
communications will cease if the specified number
of failures occur.
Initialize Output Data
Yes or No
If this parameter is set to "Yes", it prevents the
database in the module from resetting all registers
to zero after a boot-up. Instead, during power up,
the module will generate Read Blocks containing
special Write Block IDs (1000 to 1067). The
ladder logic is required to update the last data in
the PLC memory to the MVI71-HART module.
The number of blocks transferred is based on
how the ReadData register count is setup in the
module definition parameters of the loaded
configuration file. If this parameter is set to "No", it
clears the registers after boot up.
