3.2 Module Configuration Parameters
3.2.1 Module
This section contains general module configuration parameters. In the ProSoft
Configuration Builder (PCB) tree view, expand the
MVI69E-MBTCP icon, then
expand M
ODULE
, and then double-click the M
ODULE
icon.
Parameter Value Description
Module Name ASCII
characters
(max. 80) Assigns a name to the module that can be viewed using the
configuration/debug port. Use this parameter to identify the module
and the configuration file.
Read Register Start 0 to 9999 Specifies the starting address of the module's Read Data area. Data
in this area is transferred from the module to the processor.
Read Register Count 0 to 10,000 Specifies the size of the Read Data area.
Write Register Start 0 to 9999 Specifies the start of the Write Data area in module memory. Data in
this area is transferred in from the processor.
Write Register Count 0 to 10,000 Specifies the size of the Write Data area.
Failure Flag Count 0 to 65535 Specifies the number of consecutive backplane transfer failures that
can occur before Modbus communications are halted.
Error/Status Block
Pointer -1 to 9939
Starting register location in the module’s database for the error/status
table. This data must be placed in the read data range of module
memory. If a value of -1 is entered, the error/status data is not placed
in the database. All other valid values determine the starting location
of the data.
This data area includes the module version information and all server
error/status data. Refer to MBTCP.STATUS.GeneralStatus (page 88)
for more information.
Initialize Input Image Yes or No
This parameter determines if the input image data and the module’s
Read Register Data values are initialized with Read Register Data
values from the processor. If you set the parameter to No, the Read
Register Data values in the module are set to 0 upon initialization. If
you set the parameter to Yes, the data is initialized with Read
Register Data values from the processor. Using this option requires
associated ladder logic to pass the data from the processor to the
module.
Block Transfer Size 60, 120 or
240 Specifies the number of words in each block transferred between the
module and processor.
Slot Number 1 to x Specifies the slot in the CompactLogix rack for the module.
Important: The sum of the Read Register Count and Write Register Count cannot exceed 10,000
total registers. Furthermore, neither the Read Data nor the Write Data area may extend above
module register 9999. The Read Data and Write Data areas must have separate address ranges in
the module database and must not overlap.
